Effects of assimilate enhancement on grain filling and carbohydrate and nitrogen partitioning in maize.
Provedor de dados: 119
Autores: MAGALHAES, P. C.
Source-sink relationhips is a controversial topic. Some workers assert that grain yield in corn is limited by availability of assimilate during the grain filling period. Others have reported the sink size as the limiting factor. In this research, I studied the effects of assimilate availabilibty on kernel growth rate and final weight by investigating the effects of altered source/sink ratios on soluble sugars, starch and nitrogen content in plant parts of maize. Special attention was given to plant's compensatory response such as soluble carbohydrates and nitrogen redistribution to the grain. Two genotypes: M14 x W64A and Pionner-brand '3780', were grown in field plots at St. Paul, Mn in 1982. The treatment were arranged in a split plot manner in a...

Abstract: Coffee (Coffea spp.), a globally traded commodity, is a slow-growing tropical tree species that displays an improved photosynthetic performance when grown under elevated atmospheric CO2 concentrations ([CO2]). To investigate the mechanisms underlying this response, two commercial coffee cultivars (Catuaí and Obatã) were grown using the first free-air CO2 enrichment (FACE) facility in Latin America. Measurements were conducted in two contrasting growth seasons, which were characterized by the high (February) and low (August) sink demand. Elevated [CO2] led to increases in net photosynthetic rates (A) in parallel with decreased photorespiration rates, with no photochemical limitations to A. The stimulation of A by elevated CO2 supply was more...

Provedor de dados: 119
Autores: ROWLAND, L.; COSTA, A. C. L. da; OLIVEIRA, R. S.; BITTENCOURT, P. R. L.; GILES, A. L.; COUGHLIN, I.; COSTA, P. de B.; BARTHOLOMEW, D.; DOMINGUES, T. F.; MIATTO, R. C.; FERREIRA, L. V.; VASCONCELOS, S. S.; S. JUNIOR, J. A.; OLIVEIRA, A. A. R.; MENCUCCINI, M.; MEIR, P.
Whether tropical trees acclimate to long&amp;#8208;term drought stress remains unclear. This uncertainty is amplified if drought stress is accompanied by changes in other drivers such as the increases in canopy light exposure that might be induced by tree mortality or other disturbances. Photosynthetic capacity, leaf respiration, non&amp;#8208;structural carbohydrate (NSC) storage and stomatal conductance were measured on 162 trees at the world's longest running (15 years) tropical forest drought experiment. We test whether surviving trees have altered strategies for carbon storage and carbon use in the drier and elevated light conditions present following drought&amp;#8208;related tree mortality. Relative to control trees, the surviving trees experiencing...

Coffee is currently the second largest commodity on the world market today, and there is great concern about the quality of the beans exported from producer countries to Europe and USA. Practices such as using blends of different species and adding low-cost raw materials, such as chicory, corn, and soybean, impair the sensory and functional characteristics of the drink made from roasted and ground coffee beans. There is a need to adopt more efficient analytical methods than the microscopy technique currently used. The first chromatographic method used to determine fraud was reported in 1958. This method used paper chromatography to differentiate between coffee and chicory based on the free reducing sugars. As of the 1980s, different methods involving...

Abstract: The effects of nitrogen (N) and/or phosphorus (P) starvation on the biochemical composition of native microalgae Chlorella spp. polyculture obtained from the phycoremediation of swine wastewaters were investigated. Microalgae-specific growth rate of 1.2 day(-1) was achieved (30.3 mg L(-1) day(-1)). PO4 (-2) and NH3 were completely removed from swine digestate effluent after 3 and 11 days, respectively. Microalgae harvested immediately after nutrient removal showed high protein (56-59 %) and carbohydrate (25-34 %) but low lipid (1.8-3 %) contents. Depletion of N or P alone stimulated carbohydrate production at the expenses of proteins. Significant lipid accumulation from 3 %&amp;#8201;±&amp;#8201;0.5 to 16.3 %&amp;#8201;±&amp;#8201;0.8 was reached...

ABSTRACT Soybeans contain about 30% carbohydrate, mainly consisting of non-starch polysaccharides (NSP) and oligosaccharides. NSP are not hydrolyzed in the gastrointestinal tract of monogastric animals. These NSP negatively affect the development of these animals, especially the soluble fraction. This work aimed to establish a method to quantify NSP in soybeans, using high performance liquid chromatography (HPLC), and to estimate correlations between NSP, oligosaccharides, protein and oil. Sucrose, raffinose + stachyose, soluble and insoluble NSP contents were determined by HPLC. Oil and protein contents were determined by near-infrared spectroscopy (NIRS). The soluble PNAs content showed no significant correlation with protein, oil, sucrose and raffinose...

We report the antinociceptive activity, determined by the writhing, formalin and hot-plate tests in mice, of crude (F0/60), lectin and carbohydrate fractions isolated by ammonium sulfate precipitation (0 to 60%) from Bryothamnion seaforthii and B. triquetrum, species of red algae. Not only fraction F0/60 but also lectins from both species significantly inhibited acetic acid-induced abdominal contractions after intraperitoneal or oral administrations. In the formalin test, lectins (1 and 5 mg/kg, ip, and 5 to 20 mg/kg, po) inhibited the 1st and 2nd phases (5 and 20 min, respectively), but the effect occurred predominantly on the 2nd phase. The effects of the lectins were totally or partially reversed by naloxone (2 mg/kg, sc) in the 1st and 2nd phases,...

This paper investigated changes in growth and carbohydrate content of shoots and root systems in response to source-sink manipulation in field-grown coffee trees. The source-sink manipulations were carried out using manual de-fruiting. Two plots of trees were established: in one group, the fruit was left on the tree, while in the second group all fruits were removed manually. Similar results were obtained for coffee trees with and without fruit in terms of height, stem and skirt diameter and branch lengths. A biochemical evaluation of the roots showed that no differences were found between the levels of carbohydrates. In the leaves, levels of soluble sugars and reducing sugars were higher in plants with fruit. The starch concentration in leaves and roots...

Autores: Mattiuz,Claudia Fabrino Machado; Mattiuz,Ben-Hur; Rodrigues,Teresinha de Jesus Deléo; Marques,Kelly Magalhães; Martins,Ramilo Nogueira.
The orchid Oncidium varicosum is a tropical plant with significant commercial value due to the beauty of its yellow inflorescences. Several authors have observed a reduction in the water content of cut flowers, consequently, wilting and senescence of petals are the main reasons for the termination of the decorative life of cut flowers. In this research, we studied the effects of several chemical compounds on the postharvest life of cut inflorescences of Oncidium varicosum 'Samurai'. These chemicals are as follows: sucrose (5%) plus 8-hidroxiquinoline citrate (8-HQC) (100 mg L-1) plus silver nitrate (AgNO3) (50 mg L-1); sucrose (5%) plus citric acid (75 mg L-1); quaternary ammonia at 30% (50 mg L-1); and sucrose (5%) plus quaternary ammonia at 30% (50 mg...

Abstract Partial-hydrothermal hydrolysis using pressurized hot water was applied in waste turmeric, derived from extraction processes that employed supercritical and pressurized fluids, as a sustainable alternative for the recovery of bioactive constituents from this material. The reaction products consisted of a liquid extract of fermentable sugars and a solid fraction, which is a mixed biopolymer with relevant composition in terms of starch and antioxidant constituents. The effects of reaction conditions on resulting products were investigated. Economic evaluation was also performed showing that application of partial-hydrothermal hydrolysis from a residual feedstock is feasible in terms of low spend of energy and materials.

Brazil is the third largest producer of pineapple (Ananas comosus) and the market for fresh pineapple is sustained by the Hawaii and Perola cultivars. In this work the Perola cultivar was divided into three main parts, shell, core and pulp, for characterization. Moisture in the pulp was higher (between 10 and 15%) than in the shell and core. The amount of protein was higher in the core (35%) than in the pulp and shell. Perola contained relatively low concentrations of total ascorbic acid in the edible parts, although higher levels of ascorbic acid in the shell. Citric acid corresponded to almost 60% of the total organic acids. The total soluble sugars [~7-12% (FW)] were predominantly sucrose, fructose and glucose. The core had almost twice as much total...

The aim of this study was to evaluate the effects of hydrocooling on the postharvest shelf life of butter lettuce 'Vitória de Santo Antão'. The lettuce heads, after selection, were subjected to the following treatments: T1= hydrocooling followed by storage at 5°C in the cold chamber; T2= storage in the cold chamber at 5°C without hydrocooling; T3= hydrocooling followed by storage at 22°C and T4= storage at 22°C without hydrocooling. We determined the shelf life, leaves mass loss, chlorophyll content, relative water content, total soluble sugars content, reducing sugars, non-reducing sugars and starch. The data were analyzed in...

Белки, аминокислоты и углеводы в прибрежных наносах Севастопольской бухты Черного моря
Provedor de dados: 13
Autores: Миронов, О. Г.; Гапонюк, Т. О.; Муравьева, И. П.; Замыслова, Т. Н.
В прибрежных наносах линии уреза северного побережья Севастопольской бухты впервые определено содержание белков, аминокислот и углеводов. Установлено преобладание количества белков над углеводами, в то время как в море в целом преобладают углеводные соединения. Если в целом в Севастопольской бухте наблюдаются сезонные колебания концентрации органических веществ, то в условиях наносов, постоянно омывающихся морской водой, сезонная динамика не наблюдается. Отношение концентрации углеводов к белку в наносах составляет десятые и сотые доли, что в десятки раз ниже, чем в поверхностном слое грунтов как открытого моря, так и бухт. Средняя концентрация белков и углеводов в наносах выше, чем в грунтах того же механического состава.

Provedor de dados: 5
Autores: D'Souza, F; Bhosle, Nb.
Suspended particulate material was analysed for particulate carbohydrate concentration and composition and for the bulk parameters: suspended particulate matter, chlorophyll a, particulate organic carbon, particulate organic nitrogen and particulate proteins. Chlorophyll a concentrations increased from May 7 to 15 due to the development of a small scale bloom of diatom Navicula sp. and decreased for the remaining period after the premonsoon rain on 16 and 17 May. Concentrations of particulate organic carbon, organic nitrogen, carbohydrates and proteins increased with the increase in chlorophyll a concentration. Together particulate protein-carbon and carbohydrate-carbon accounted for 10 to 30% of the organic carbon. Glucose contributed 26 to 81% to the...

The nutritional requirements of the Japanese shrimp Penaeus japonicus
Provedor de dados: 5
Autores: Guillaume, Julien.
Penaeus japonicus is probably the best known species among penaeids or even among shrimps. In juveniles, the protein requirement was best studied and Japanese shrimp appears as the most demanding penaeid species. They may be related to several factors such as energy level of the diet, digestibility or biological value of protein or other nutritional factors. The essential amino acids are well known, however from a quantitative point of view the requirements in each of these amino acids remain to be determined.

Energy-protein management by some warmwater finfishes.
Provedor de dados: 5
Autores: Luguet, P; Moreau, Y.
If warmwater finfish protein requirements as level in diet is low, absolute intake per day is similar to those of coldwater species. But relation of this requirement with specific growth rate differs for strictly warmwater fishes as Tilapias. Analysis of partition between protein and non-protein energy retention shows that these species with Clarias make a better use of non-protein energy provided and consequently improve their protein retention. Better carbohydrate digestibility and metabolism are propounded as part of the explanation.

A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Protein requirements of Penaeid shrimp.
Provedor de dados: 5
Autores: Kanazawa, A.
Proteins are indispensable nutrients for growth and maintenance of live of all animals. The optimum protein levels in diets for shrimps are different among the various species. Squid meal is an effective protein source for many penaeids. The effects of dietary protein, lipid, and carbohydrate levels on the growth and survival of larvae of Penaeus japonicus were examined by feeding trials using purified diet with carrageenan as a binder. As a result, the effects of protein levels on growth and survival of P. japonicus larvae varied with dietary carbohydrate levels but not dietary lipid levels.

Small-scale variability of zooplankton pyruvate kinase activity in the Gironde Estuary plume (Atlantic French Coast): A case study under unusually low freshwater discharge
Provedor de dados: 5
Autores: Bergeron, Jean-pierre.
Pyruvate kinase (PK) activity measurements are used to assess the role of carbohydrates in global feeding of mesozooplankton communities inhabiting an estuary plume. As a consequence of a remarkably low freshwater discharge rate, the sea surface layers of the area under estuarine influence showed a very moderate salinity fall and a nearly total depletion in nitrates, whereas higher levels of these nutrients were found in deeper, more saline, layers. Small-scale PK activity variations in mesozooplankton appear to be closely correlated to nitrate integration values within the water column. The results were analysed in comparison with literature reports. The study produced a coherent overall interpretation, which strongly supports the reliability of this new...

Identification of transcription factors involved in the phenotype of a domesticated oleaginous microalgae strain of Tisochrysis lutea
Provedor de dados: 5
Autores: Thiriet-rupert, Stanislas; Carrier, Gregory; Trottier, Camille; Eveillard, D.; Schoefs, B.; Bougaran, Gael; Cadoret, Jean-paul; Chenais, B.; Saint-jean, Bruno.
Microalgae are an outstanding source of high value products with applications in food, feed or biofuel production. Among these promising organisms, the haptophyte Tisochrysis lutea is commonly used as a feed for shellfish and shrimps in aquaculture. Its capacity to produce high amounts of docosahexanoic acid and storage lipids is also of economic interest for nutrition and energy production. Consequently, understanding its lipid accumulation under nitrogen deprivation is of major interest. Here, we aimed to identify Transcription Factors (TFs) involved in the establishment of the mutant phenotype of the 2Xc1 strain of T. lutea, which accumulates double the quantity of storage lipids under nitrogen deprivation than the wild type strain (WTc1). Strains were...

Temporal variability in the biochemical composition of sedimentary organic matter in an intertidal flat of the Galician coast (NW Spain)
Provedor de dados: 5
Autores: Cividanes, S; Incera, M; Lopez, J.
Temporal variations and spatial distribution of sedimentary organic matter composition were investigated over a one year period in an intertidal flat of the NW Spain. Sediment samples were collected from 0 to 25 cm depth, every three months, from January 1997 to January 1998 at three tidal levels (high, medium and low). Changes in the elemental and biochemical composition were assessed to gather information on temporal and spatial fluctuations in quantity and quality of sedimentary organic matter potentially available to benthic deposit-feeder nutrition. Organic matter content was significantly higher at the medium tidal level, while minimum values were found at the high tidal level. The different biochemical classes of organic compounds exhibited...

Larval rearings were performed with seawater either freshly pumped or after storage in a pond. Concerning bacterial populations these waters were characterized by a high diversity, little sized bacteria whose few of them (1%) were cultivable on Zobell medium. In the tanks, the bacterial ecosystem was modified by the presence of antibiotics, larvae and algae: the diversity was lowered, the cellular volume was increased by a factor 2 to 5, 100% bacteria were cultivable and chloramphenicol resistant, and their metabolism changed. Taxonomic screening showed no differences among the two waters neither at the beginning nor at the end of the rearings. However, depending on the water (stored or not) differences were identified for bacterial physiology and...

Reference diet for crustaceans: Principle of experimentation.
Provedor de dados: 5
Autores: Castell, J.
Feeding trials were conducted with over 22 different crustacean species to compare the potential use of two diets as Standard Reference Diets (SRD) in crustacean research. The two diets (BML 81 S, a casein/albumin based formula developed at the University of California, Bodega Marine Laboratory, and HFX CRD 84, a crab protein concentrate based diet formulated at the Canadian Department of Fisheries and Oceans Halifax Laboratory) were about equal in performance for most species tested. Though neither diet was an ideal SRD, the HFX CRD 84 formulation based upon a purified protein of marine origin was accepted as the interim SRD for use in aquatic crustacean studies.

Adhesion of micro-organisms to surfaces in marine environments leads to biofouling. The deleterious effects of biofilm growth in the marine environment are numerous and include : energy losses due to increased fluid frictional resistance or to increased heat transfer resistance, risk of corrosion induced by micro-organisms, loss of optical properties, quality control and safety problems. Antifouling agents are generally used to protect surfaces from being affected by such a biofilm. These agents are toxic and can be persistent, causing harmful environmental and ecological effects. Moreover, the use of biocides and regular cleaning considerably increase the maintenance costs of marine industries. An improved knowledge of the biofilm adhesion mechanisms is...

Many of Glycobyological aspects of human development remain still unclear, mainly in oral science, and this could be observed in a lack of literature with few and old papers about this subject. During tooth histo-morphogenesis changes occur in basement membrane composition, expression of signaling molecules and in localization of cell surface components, where glyco components could be involved. In this sense, this work aimed to analyze the ConA ligands commonly founded in glycoproteins cores and UEA-I ligands since fucolization is a Key event in many physiological and pathological processes. Therefore 15 jaws of human fetuses were ethically obtained, histologicaly processed and then submitted to lectin histochemistry with appropriated controls. The...

The objectives of this work were to analyze seeds from 20 trees of aroeira (Myracrodruon urundeuva Fr. All.) of a natural population located in the region of Selvíria, State of Mato Grosso do Sul, Brazil, in order to evaluate their protein, lipid and carbohydrate contents, and to estimate their genetic variation. A completely randomized experimental design consisting of 20 treatments (families) was set up, with two replications. Four types of proteins were detected: albumin (35.0 to 107.3 mg/g seed), globulin (3.4 to 9.3 mg/g), prolamin (60.0 to 135.2 mg/g) and glutelin (118.0 to 286.0 mg/g). The lipid content varied between 200 and 334 mg/g seed. The total sugars also varied (26.5 to 46.3 mg/g seed), with a predominance of polyols (arabinitol, mannitol,...

The Aquatic system contamination by organic pollutants and heavy metals is one of the most serious problems that might face the environment and organisms as a whole. Interestingly, the accumulation of these pollutants is due to the anthropogenic activity, namely the intensive use of fertilizers to obtain high yields in crop production. In this paper, we compared the levels of chlorophylls, proteins, dry weight and sucrose in some red (Alsidium sp. and Gracilaria sp.) and green algae (Ulva sp.) collected from Mohandis, near Kariat and Bou Areg. Our results indicate that the algae collected nearby Bou Areg, an area well-known for its high agricultural activity, contained high levels of pigments, proteins and sugars. From the chlorophyll results, we conclude...

Seed reserve composition and mobilization during germination and initial seedling development of Euphorbia heterophylla
Provedor de dados: 93
Autores: SUDA,CECILIA N.K.; GIORGINI,JARBAS F.
Seed composition and reserve mobilization were investigated in wild poinsettia (Euphorbia heterophylla L.). Lipids, around 60% of seed dry mass, are the major reserve. Proteins, including albumins (49%), salt insoluble globulins (30%), salt-soluble globulins (21%) and prolamins (0.3%), comprise about a quarter of seed dry mass. Soluble sugars comprise about 3.6% of seed dry mass, sucrose being the predominant sugar. Starch was not detected in the endosperm of E. heterophylla. Lipid depletion starts after initial imbibition, and is completed between 72 and 96 hours. Protein fractions exhibit different degradation patterns, salt-soluble globulins being continuously degraded after the start of imbibition whereas salt insoluble fractions are degraded between...

Autores: PYSTINA,NATALIA V.; DANILOV,ROMAN A.
Influence of different light regimes (plants grown in shade and in the sun) on respiration, activity of alternative respiratory pathway and carbohydrates content in mature leaves of Ajuga reptans L. was investigated. All experiments were carried out under natural conditions. Sun plants had higher respiration, activity of the alternative pathway and carbohydrates content compared to the shade plants. Additional experiments were performed in order to study effects of darkening as well as evolution of respiration and carbohydrates concentrations in leaves of A. reptans during the day. Darkening led to a decline in total respiration in all types of plants investigated. Activity of the alternative pathway remained unchanged by 20 % in the leaves of the shade...

Provedor de dados: 95
Autores: Corte,Viviana Borges; Borges,Eduardo Euclydes de Lima e; Gonçalves,José Francisco de Carvalho; Silva,Mirian Sousa.
The decay of seeds is irreversible and at best can only be delayed by applying techniques that reduce the velocity of the metabolic reactions involved. There is little information on the biochemistry of tropical forest tree seeds related to their storability. It was investigated the influence of the composition of lipids and soluble sugars of two storage compartments, the cotyledons and the embryonic axis, of Melanoxylon brauna Schot. (Leguminosae- Caesalpinioideae), a hardwood known as black brauna, seeds stored at 20 ºC for 0, 3, 6, 9 and 12 months (natural ageing) and for 0, 24, 48, 72 and 96 hours at 40 ºC (accelerated ageing). The levels of fatty acids and monosaccharides varied differentially in each of the embryo storage compartments. Changes in...

Ruminal fermentation modification of protein and carbohydrate by means of roasted and estimation of microbial protein synthesis
Provedor de dados: 96
Autores: Andrade-Montemayor,Héctor; García Gasca,Teresa; Kawas,Jorge.
The animal meal prohibition as a protein source with low ruminal degradability in ruminant nutrition, creates the need to seek alternatives, as legume seeds, however, its protein, have a high degradability, which could generate losses of nitrogen in the rumen. Other problem in the legume seeds is the content of antinutritional factors such as protease inhibitors, tannins, phenolic compounds, lectins and some others, could affect the digestibility. One alternative to decrease the degradability of the protein and/or decrease the activity of some antinutritional factors is the use of different technological treatments such as roasting. Microbial protein synthesis is dependent on the availability of nitrogen or amino acids and of the degradable carbohydrate...

Chilling privation during dormancy period and carbohydrate mobilization in Japanese pear trees
Provedor de dados: 63
Autores: Marafon,Anderson Carlos; Citadin,Idemir; Amarante,Luciano do; Herter,Flávio Gilberto; Hawerroth,Fernando José.
The flower bud abortion is one of the main problems that limit commercial pear (Pyrus pyrifolia) production in the southern region of Brazil. Insufficient chilling during the dormancy period is known as the main factor of this problem. One of the hypotheses to explain this problem is that the starch mobilization and carbohydrate fluxes to the buds are impeded when mild temperatures occurred during winter. This study compared the total soluble sugars (TSS) and reducing sugars (RS) concentrations, the cell wall acid invertase (CWAI - EC 3.2.1.26) and sucrose-phosphate synthase (SPS - EC 2.4.1.14) activities in wood of branches and floral buds of Japanese pear trees cv. Housui, grafted on Pyrus calleryana and submitted to chilling conditions during the...

Nutritive value of diets with different carbohydrates for adult Anastrepha obliqua (Macquart) (Diptera, Tephritidae)
Provedor de dados: 104
Autores: Fontellas,Tânia Mara de Lima; Zucoloto,Fernando Sérgio.
Adult Tephritidae, especially of the genus Anastrepha (Schiner, 1868), have been observed to feed on a wide variety of natural diets. The fruit on which they feed, in general, are rich in sugar content, chiefly glucose, frutose and sucrose, which are also the sugars that those insects utilise better. Neither the behavioural mechanisms, nor the physiological ones, that control food selection by insects, are well known. Because some of those aspects are not known for the species Anastrepha obliqua (Macquart, 1835) either, and in order to understand their biology better, three experiments were conducted. In the first experiment, it was checked whether there was a difference in metabolic profit by those insects, when fed the carbohydrates more frequently found...
