| The Leukocyte Immunoglobulin-like Receptors (LILRs) are a family of receptors that was broadly expressed on all leukocytes and have the ability to regulate their function. The increased levels of human LILRA3 in rheumatoid arthritis patients leads to stroke. In quest of designing novel inhibitors against LILRA3 an accurate homology model for the protein was based on crystal structures of 1GOX and 3P2T using Modeller 9V9. The use of multiple templates for structure prediction led us to propose a structure comprising all 439 amino acids of human LILRA3 for the first time. The best model was selected based on GA341 and DOPE score and further assessed through ProSA and PROCHECK. The validated structure was subjected to CASTp analysis ligand binding site... |

| The objective of general surveillance is to identify the occurrence of unanticipated adverse effects of GM crops on human health or the environment that were not covered in the environmental risk assessment. EuropaBio is harmonizing an approach to non-hypothesis driven post-market environmental monitoring relating to the cultivation of different GM crops, comprising a farmer questionnaire, existing surveillance systems as well as other data sources. As an unanticipated adverse effect is most likely to occur where the level of environmental exposure is highest, general surveillance focuses on the agricultural environment and those agronomic zones that are representative of commercial GM crop cultivation. The farmer questionnaire is one element of the... |

| The aim of this work was to study, as a function of the different availability of nitrogen in the reduced form, mineral and organic, the induction of the synthesis of some ROS-scavenging molecules and the evolution of some enzymatic activities such as ascorbate peroxidase (APX) and polyphenoloxidase (PPO). 
Chicory seedlings were grown in nutritive solution for 35 days in controlled conditions. On the 14th day, one third of the plants was transferred into a nutritive solution containing (NH4)2SO4 60 mM, one third was transferred into a medium containing Urea 60 mM, and the remaining was let grow into the nutrition solution, as a control. Three samplings of leaves were performed, respectively after 21, 28 and 35 days of... |

| With the environmental risk assessment (ERA) for genetically modified plants (GMP) the identification of equivalence or differences in the composition of ingredients of GMPs and non-GMPs has to be investigated. The strategy is based upon the idea that traditionally cultivated crops have been used safely for many years, thus every divergence within the compounds of a GMP in contrast to its non-GMP counterpart could refer to a risk and has to be further analysed.

The BioOK company offers the opportunity to analyse very different aspects from the ERA of GMPs in one hand. Beside toxicological analysis and the determination of environmental effects via soil analysis, we can look into several plant metabolites to identify... |

| The soybean-derived products are among the most important agricultural products in the USA and the world. Conventional analytical methods for soybean composition analysis are both time consuming and costly. Faster and less expensive methods are required for most practical applications. To improve the accuracy, reliability and sensitivity of NIR, major advancements in instrumentation, as well as, data analysis / calibration methodology are required. Novel NIR instruments, such as DA-NIR and FT-NIR spectrometers developed in recent years have the potential for improving significantly the quantification of soybean composition at a reasonable cost. We present representative calibrations and data for intact soybean composition analysis obtained at the... |

| Grassland management experiment (GrassMan) was set up in 2008 on a permanent semi-natural grassland in the Solling uplands, Germany. The main research focus is on the ecosystem functioning of the phytodiverse grassland (e.g. productivity and forage quality, water and nutrient fluxes). The aim of our study was to analyse the effects of vegetation composition and functional diversity on productivity and forage quality of the semi-natural permanent grassland. Variation in sward composition was achieved by herbicide application and resulted in three sward types: control sward type (without herbicide application), monocot-reduced and dicot-reduced. Further management factors included different nutrient input levels (without fertilizer and 180-30-100 kg/ha of... |

| Background/Question/Methods 
_Abies sachalinensis_ (Sakhalin Fir) and _Picea glehnii_ (Glehn’s Spruce) are major components of the sub-boreal forests of Hokkaido, Japan. Similar Spruce-Fir forests can be found in many other places in the northern hemisphere and will probably be impacted by global warming. Therefore, detailed knowledge of these species’ physiology and life-history strategies at different growth stages is important to understand present communities and to support reliable prediction of possible consequences of global climate change. 
Accordingly, the objective of this study was to establish relations between community dynamics, life-history strategies and photosynthetic adaptation of... |

| The soils of tropical tasar plantation fields in general are sloppy and are primarily deficient of nutrition due to top soil erosion and constant leaf productivity exploitation to rear tasar silk insect, Antheraea mylitta Drury. The rainfed field of Terminalia tomentosa (W&A) plantation has been evaluated for soil fortification with green mulching through legumes, Sun hemp (Crotalaria juncea), Daincha (Sesbania aculeata), Green gram (Vigna radiatus) and Black gram (Vigna mungo) during rainy season. The mulching has enhanced the water holding, moisture retention, electrical conductivity, organic carbon, nitrogen (N) and potassium (K) and reduced the bulk density and pore space of soil. Among the legumes, Sun hemp has shown higher improvement of... |

| Carnivorous plants comprise roughly 0.24 percent of the flowering plants, or 640 species represented in 12 families. Yet they are regarded as _miracula naturae_. Over fifty percent of these taxa are represented in a single family, namely Lentibulariaceae. Carnivorous plants are generally insectivorous, and carnivory in flowering plants is generally found in taxa that are adapted to nutrient-deficient habitats. The extra nutrients such plants acquire by special ways serve merely as supplements. The origin and evolution of carnivorous plants is a mystery in the phylogenetic tree of angiosperms, they often appear without a clear linkage. Here, we report that _Nymphaea nouchali_ Burm. f. (a cultivar of var. cernua), a large aquatic member of the family... |

| Consumption of fruits and vegetables is shown to be beneficial for protecting health and preventing some chronic diseases such as cancer, cardiovascular disease, and stroke. The positive health effects have been mainly due to the contributions of their natural antioxidant capacity. Chokecherry (Prunus virginiana), a unique fruit, is a member of the Rose family and native to North America. Here we demonstrate that chokecherry fruit with strong antioxidant capacity is available in Manitoba, and that its potent antioxidant potential can be developed for health benefits in value-added applications.These findings are useful for developing novel value-added antioxidant products from chokecherry because of its phytochemical profile associated with health... |

| Mitosis is nuclear division plus cytokinesis,and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. However, a new nucleus behavior in interspecific hybrid progenies of Lilium was observed in our experiment. Very unusual behaviors of nuclei surprisingly presented during the mitosis, such as sprouting or germination, tube-like elongation, penetrating cell membrane into a neighbor cell, the top of nuclei tube expanding, intruding and splitting of the tube-like nucleus, and micronucleus formation, and so on. Furthermore, the tetrad of meiosis was founded in mitosis of root.

Routine of the unusual nucleus behaviors observed in our experiment may be summarized as nucleus... |

| PlnTFDB is a publicly available computational resource comprising putative complete sets of transcription factors from plants. The original database listed the putative complete sets of TFs from five different green plant (viridiplantae) species. Up to date, summer 2007, PlnTFDB have had more than one hundred thousand hits from more than one thousand different clients, showing the importance that this resource had acquired for the plant community. In this first major update, we extended the coverage of the database to additional completed viridiplantae genomes, i.e., the moss _Physcomitrella patens_ and the rice _Oryza sativa_ spp _indica_. The scope of PlnTFDB was broadened to encompass other eukaryote photosynthetic organisms, such as the rhodophyte... |

| AMBIGUOUS DEPENDENCE OF MINIMAL PLANT GENERATION TIME ON NUCLEAR DNA CONTENT Victor B. Ivanov The minimum generation time (MGT) of plant development was suggested to depend on nuclear DNA content, which varies in plants over wide limits1. In ephemeral species with the shortest MGT, the average C values were significantly lower than in annual species, whereas the average C values in annual species were lower than those in perennial plants. However, nobody has paid attention to the ratio of annual to perennial species number as a function of C values. Here I show that with increasing C the ratio of annual to perennial species increases to C values equal to 7-8 pg (monocots) and 6-7 pg (eudicots) and then decreases and that the fraction of annuals is abundant... |

| Sumac is the common name for a genus (Rhus) with >250 individual species of flowering plants in the family Anacardiaceae. These plants are globally distributed in temperate and tropical regions and can grow on marginal lands, making them strong candidates for renewable bioproduct sources. Despite the extensive historical use of some members of Rhus spp. for tannins and other commercial phenolics, little is known about the non-phenolic components of extracts and essentials oils. The current review highlights opportunities available to extend these limited prior studies to other sumac species, and for obtaining value-added compounds to complement already established phenolic extractions in these commercial plant species. To date, a number of... |

| Flowering plants (angiosperms) appeared on Earth rather suddenly approximately 130 million years ago and underwent a massive expansion in the subsequent 10-12 million years. Current molecular phylogenies have predominantly identified _Amborella_, followed by _Nymphaea_ (water lilies) or _Amborella_ plus _Nymphaea_, in the ANITA clade (_Amborella_, Nymphaeales, Illiciaceae, Trimeniaceae and Austrobaileyaceae) as the earliest angiosperm. However, developmental studies suggest that the earliest angiosperm had a 4-cell/4-nucleus female gametophyte and a diploid endosperm represented by _Nymphaea_, suggesting that _Amborella_, having an 8-cell/9-nucleus female gametophyte and a triploid endosperm, cannot be representative of the basal angiosperm. This... |
