Simple method to prepare DNA templates from a slice of peanut cotyledonary tissue for Polymerase Chain Reaction
Provedor de dados: Electronic Journal of Biotechnology
Autores: Yu,Shu Tao; Wang,Chuan Tang; Yu,Shan Lin; Wang,Xiu Zhen; Tang,Yue Yi; Chen,Dian Xu; Zhang,Jian Cheng.
An efficient DNA extraction method was developed for peanut seed, where only 3-5 mg cotyledonary tissue was enough for more than 50 PCR reactions with a reaction volume of 15 &amp;#956;l. Both low copy number and high copy number DNA sequences were successfully amplified. Processing one seed sample only took about half an hour. Sampling had no significant effects on germination and development. The DNA extraction method makes it possible to identify transformants and conduct molecular marker studies prior to sowing, and thus may greatly hasten research progress.

Provedor de dados: Electronic Journal of Biotechnology
Autores: Tang Wang,Chuan; Dao Yang,Xin; Xu Chen,Dian; Lin Yu,Shan; Zhen Liu,Guang; Yi Tang,Yue; Zhi Xu,Jian.
SSRs have proved to be the most powerful tool for variety identification in groundnut of similar origin, and have much potential in genetic and breeding studies. To facilitate SSR discovery in groundnut, we proposed a highly simplified SSR isolation protocol based on multiple enzyme digestion/ligation, mixed biotin-labeled probes and streptavidin coated magnetic beads hybridization capture strategy. Of the 272 colonies randomly picked for sequencing, 119 were found to have unique SSR inserts

Characterization of Brazilian accessions of wild Arachis species of section Arachis (Fabaceae) using heterochromatin detection and fluorescence in situ hybridization (FISH)
Provedor de dados: Genetics and Molecular Biology
Autores: Custódio,Adriana Regina; Seijo,Guillermo; Valls,José Francisco Montenegro.
The cytogenetic characterization of Arachis species is useful for assessing the genomes present in this genus, for establishing the relationship among their representatives and for understanding the variability in the available germplasm. In this study, we used fluorescence in situ hybridization (FISH) to examine the distribution patterns of heterochromatin and rDNA genes in 12 Brazilian accessions of five species of the taxonomic section Arachis. The heterochromatic pattern varied considerably among the species: complements with centromeric bands in all of the chromosomes (A. hoehnei) and complements completely devoid of heterochromatin (A. gregoryi, A. magna) were observed. The number of 45S rDNA loci ranged from two (A. gregoryi) to eight (A....

十勝地方におけるラッカセイ生産の可能性を模索するため、帯広畜産大学実験圃場でラッカセイ品種「千葉半立」、「ナカテユタカ」、および「おおまさり」の栽培を行った。栽植方法（直播、あるいは移植）、および栽植密度（標準植：5.1 株/ ㎡、あるいは密植：7.7 株/ ㎡）の組合せによる4 試験区を設け、2016 年5 月23 日にそれぞれの品種の栽培を開始した。茎葉の黄変期に収穫を行い、収量構成要素や子実収量の評価を行った。千葉半立とナカテユタカでは、子実収量に対する栽植方法と栽植密度の効果が認められた。両品種とも移植を行った試験区で直播を行った試験区に比べ収量が高かった。これは、移植を行うことで単位面積当たりの稔実粒数が増加することに起因する。また、両品種とも密植を行った試験区で標準植を行った試験区に比べ収量が高かった。千葉半立は半立ち性、ナカテユタカは立性の草型をもつため光競合を起こしにくく、十勝地方で栽培する場合には都府県の慣行法よりも栽植密度を高めることで土地利用効率が高まり、子実収量が改善されると考えられる。おおまさりでは、子実収量に対して栽植方法の効果のみが認められた。移植を行うことで直播を行った場合に比べ総稔実粒数や1000 粒重が高まり、子実収量が増加した。一方、おおまさりでは子実収量に対する栽植密度の効果が認められなかった。おおまさりは伏性の草型を持つため光競合が起こりやすく、十勝地方においても密植条件下では密度障害が生じ増収につながらないと考えられる。千葉半立とナカテユタカでは、移植・密植の処理組合せによる試験区で、おおまさりでは、移植・標準植、および移植・密植の処理組合せによる試験区でそれぞれ最も子実収量が高く、いずれも子実収量の全国平均（180g/...

Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Pacheco,Georgia; Gagliardi,Rachel Fátima; Cogliatti,Mariana Buturini; Manhães,Harlen Barreira; Carneiro,Leonardo Alves; Valls,José Francisco Montenegro; Mansur,Elisabeth.
The objective of this work was to evaluate the influence of substrate and preconditioning treatments on the acclimatization of in vitro plants of Arachis retusa. Plants were transferred to Plantmax or sand, and fertilized with Hoagland's nutrient solution. Plants maintained in sand, with or without fertilizer, showed the highest survival rates. In order to evaluate the influence of in vitro preconditioning treatments, stem segments were cultured on MS medium supplemented with different sucrose concentrations. The highest survival and developmental rates were observed in plants from two accessions cultured on MS supplemented with 1.5% and 3% sucrose. Flowering and fruit production were observed after five months.

MODELING WORLD PEANUT PRODUCT MARKETS: A TOOL FOR AGRICULTURAL TRADE POLICY ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Beghin,   John C.; Matthey,   Holger.
This paper presents a new partial-equilibrium, multi-market international model developed to analyze policies affecting peanut products markets. The model covers four goods (food-quality peanuts, crush-quality peanuts, peanut oil, and groundnut cake) in 13 countries/regions (Argentina, Canada, China, the EU-15, the Gambia, India, Malawi, Mexico, Nigeria, Senegal, South Africa, the United States, and Rest of World). Welfare is evaluated by looking at consumers' equivalent variation, quasi-profits in farming (peanut farming, livestock), quasi-profits in crushing, and taxpayers' revenues and outlays implied by distortions. We calibrate the model for three recent years (1999/2000, 2000/01, and 2001/02) on historical data. We illustrate the model's...

Provedor de dados: Scientia Agricola
Autores: Fávero,Alessandra Pereira; Moraes,Sérgio Almeida de; Garcia,Antonio Augusto Franco; Valls,José Francisco Montenegro; Vello,Natal Antonio.
Groundnut (Arachis hypogaea) has an AB genome and is one of the most important oil crops in the world. The main constraints of crop management in Brazil are fungal diseases. Several species of the genus Arachis are resistant to pests and diseases. The objective of our experiments was to identify wild species belonging to the taxonomic section Arachis with either A or B (or " non-A" ) genomes that are resistant to early leaf spot (Cercospora arachidicola), late leaf spot (Cercosporidium personatum) and rust (Puccinia arachidis). For the identification of genotypes resistant to fungal diseases, bioassays with detached leaves were done in laboratory conditions, with artificial inoculation, a controlled temperature of 25ºC and a photoperiod of 10 h light/14 h...

Autores: ADEBUKOLA, ADENIGBA ADEMOLA.
Abstract A Fish feed mixing machine was designed, developed and the effect of speed and retention time on the performance of the mixer was evaluated. The mixing system was tested using three fish feed ingredients; bone meal, groundnut cake and maize grain which was purchased from the market in Akure, Ondo State, Nigeria. The moisture content of the bought ingredients was determined to be 13.1%, 14.7% and 17.5% moisture content dry basis respectively. The mixer was tested using a feed component of three equal measures of 10 kg of ground corn (maize), milled groundnut cake and bone meal which were initially retained on 2 mm, 850 µm and 150 µm sieve respectively. The experiment was replicated thrice at four retention time (5 min, 10 min, 15 min and 20 min)...

Autores: Doley,Khirood; Dudhane,Mayura; Borde,Mahesh.
Arbuscular mycorrhizal (AM) fungi can play the potential role of bio-control agent, which will enable a putative perspective in bio-protection and intensive organic agricultural practices since chemical pesticides are associated with several health hazards. The objective of this pot culture research was to study the roles played by AM fungi (Glomus fasciculatum) in the biocontrol of pathogen Sclerotium rolfsii, which is a causal agent of stem-rot in groundnut plant. The experimental design was randomized complete block with four treatments and three replicates per treatment; data were analyzed with ANOVA and treatments means were compared using Tukey test (p≤0.05). Groundnut plants were treated with AM S. rolfsii or both after 30, 60 and 90 d of planting....

Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: PRASAD,ANDHARE A.; BABU,SUBRAMANIAN.
ABSTRACT We attempted to study the compatibility among plant beneficial bacteria in the culture level by growing them near in the nutrient agar plates. Among all the bacteria tested, Rhizobium was found to inhibit the growth of other bacteria. From the compatible group of PGPR, we have selected one biofertilizer (Azospirillum brasilense strain TNAU) and one biocontrol agent (Pseudomonas fluorescens strain PF1) for further studies in the pot culture. We have also developed a bioformulation which is talc powder based, for individual bacteria and mixed culture. This formulation was used as seed treatment, soil application, seedling root dip and foliar spray in groundnut crop in vitro germination conditions. A. brasilense was found to enhance the tap root...

Autores: Singh,Diwakar; Radhakrishnan,T.; Kumar,Vinod; Bagwan,N.B.; Basu,M.S.; Dobaria,J.R.; Mishra,Gyan P.; Chanda,S.V.
Aflatoxin contamination of peanut, due to infection by Aspergillus flavus, is a major problem of rain-fed agriculture in India. In the present study, molecular characterisation of 187 Aspergillus flavus isolates, which were sampled from the peanut fields of Gujarat state in India, was performed using AFLP markers. On a pooled cluster analysis, the markers could successfully discriminate among the ‘A’, ‘B’ and ‘G’ group A. flavus isolates. PCoA analysis also showed equivalent results to the cluster analysis. Most of the isolates from one district could be clustered together, which indicated genetic similarity among the isolates. Further, a lot of genetic variability was observed within a district and within a group. The results of AMOVA test revealed that...

Effects of in vitro triacontanol on growth, antioxidant enzymes, and photosynthetic characteristics in Arachis hypogaea L.
Provedor de dados: Brazilian Journal of Plant Physiology
Autores: Verma,Aman; Malik,Chander Parkash; Gupta,Vijay Kumar; Bajaj,Bhavneet Kaur.
In vitro effects of triacontanol (TRIA) on antioxidant enzymes and photosynthetic characteristics were studied in Arachis hypogaea L. cultivars (M-13 and PBS24030). The in vitro impact of TRIA on multiplication potential was also evaluated, which was found to be best at 2.0 ml L-1 TRIA in combination with 6- Benzyl adenine (BA, 3 mg L-1) in both the groundnut cultivars. Rhizogenesis was observed in almost all the TRIA treated cultures in both the cultivars. Moreover, shoots failed to set roots, in the presence of BA. Total chlorophyll content, total soluble sugars, total soluble proteins and ascorbate peroxidase (APX; EC 1.11.1.11) activity were found to be increasing with increasing concentrations of TRIA, whether alone or in combination with BA, however,...
