| Screening of peanut seeds resulting from 0.39% sodium azide treatment with NIRS calibration equation for bulk seed samples identified a plant with more than 60% oleate. Oleate content in individual seeds of the plant, as predicted by NIRS calibration equation for intact single peanut seeds, ranged from 50.05% ~ 68.69%. Three seeds with >60% oleate thus identified were further confirmed by gas chromatography. Multiple sequence alignments of the FAD2B gene from Huayu 22 (wild type) and peanut seeds with elevated oleate (mutant type) revealed a C281T transition in the coding region causing an I94T substitution in the oleoyl-PC desaturase, which may be responsible for reduction in the enzyme activity. |

| Peanut is an important legume crop across the world. However, in contrast to most legume crops, groundnut lacks taxonomic proximity to any major model genome. A relatively large number of genomic sequences were generated from groundnut as part of a microsatellite marker development project. In the current study, a total of 1312 sequences were analyzed of which 448 contained microsatellite motifs. All sequences (GenBank Accessions: BZ999351-CC000573) were analyzed after clustering for possible similarity with publicly available sequences from Arabidopsis, Lotus, soybean and Medicago. At least 39% of the sequences analyzed had significant BLAST similarities with sequences from the four databases searched, of which nearly half (47%) found significant... |

| To isolate differentially expressed peanut genes responsive to chilling, a suppression subtractive hybridization (SSH) cDNA library was constructed for a chilling tolerant peanut cultivar A4 with mRNAs extracted from the seeds imbibed at 2ºC and 15ºC, respectively, for 24 hrs. A total of 466 cDNA clones were sequenced, from which 193 unique transcripts (73 contigs and 120 singlets) were assembled. Of these unique transcripts, 132 (68.4%) were significantly similar to the sequences in GenBank non-redundant (nr) protein database, which belonged to diverse functional categories including metabolism, signal transduction, stress response, cell defense and transcriptional regulation. The remaining 61 (31.6%) showed no similarity to either hypothetical or known... |

| Background: Based on the conserved sequences of a known NBS resistance gene, a pair of degenerate primers was designed to amplify the NBS-LRR resistance gene from peanut using PCR and RACE methods. Results: Analyzing the amino acid sequence by BLAST on NCBI, which was deduced from the 1088bp-long gene named PnAG1-2, showed that it had a certain homology with some resistance proteins, among which Arachis cardenasii resistance protein gene had the highest homology (66%). Relative quantification PCR analysis indicated that PnAG1-2 gene expresses more in J11 (an A. flavus-resistant variety) than in JH1012 (an A. flavus-susceptible variety) when the harvest time was coming. Conclusions: In this study, the NBS-LRR resistance sequence was successfully cloned from... |

| ABSTRACT The use of automatic routing significantly increases the yield and quality of agricultural operations and reduces the overlap rates between the mechanized set passes during the operation. The objective of this study was to analyse the quality of peanut sowing using automatic routing in two paths, curved and rectilinear, based on the error of parallelism and execution error, through statistical process control. The maps used came from an area of peanut seed production, in the city of Luzitânia, São Paulo, Brazil. The sowing was carried out by the execution of a project elaborated in CAD software that, for its elaboration, was taken into consideration the working width of the seeder-fertilizer, as well as the spacing of the crop. The CenterPoint RTX... |

| The genus Arachis (Fabaceae) native to South America, contains 80 species divided into nine sections, three of which contain species of special economic importance such as the cultivated peanut (Arachis hypogaea), belonging to the section Arachis, and some perennial forage species from sections Caulorrhizae and Rhizomatosae. We used microsatellite markers to assay genetic variability among 77 accessions of four species from section Rhizomatosae, the diploid Arachis burkartii (2n = 2x = 20) and the tetraploid Arachis glabrata, Arachis pseudovillosa and Arachis nitida (2n = 4x = 40). A total of 249 alleles were found in the fifteen loci analyzed and a high degree of intra and interspecific polymorphism was detected. The lowest intraspecific variation... |

| Amplified Fragment Length Polymorphism (AFLP) was used to establish the genetic relationships among 20 species from seven of the nine sections of genus Arachis. The level of polymorphism among nine accessions of the cultivated peanut, A. hypogaea L., was also evaluated. Three combinations of primers were used to amplify the AFLPs. The fragments were separated in 6% denaturing acrylamide gels. A total of 408 fragments were analyzed. An average of 135.3 fragments per primer combination were scored, and the largest number of fragments was 169 using primer combination Eco RI - ACC / Mse I - CTG, while the lowest was 108, with Eco RI - ACT / Mse I - CTT. In general, the genetic relationships established using AFLPs agreed with the classification established... |

| RESUMO: O ensaio objetivou avaliar a adaptabilidade de acessos de Arachis spp. em várzea (solo Glei Pouco Húmico) na Embrapa Cerrados, Planaltina, DF, no período de novembro de 1998 a maio de 2002. O plantio foi realizado com material vegetativo (estolões) em parcelas constituídas de quatro linhas de 2 m de comprimento, espaçadas entre si em 0,5 metro, com área total de 4 metros quadrados e área útil de 1 metro quadrado. O delineamento experimental foi o de blocos ao acaso com quatro repetições. Os tratamentos estudados consistiram de dez acessos de Arachis spp. (BRA 15121, BRA 22683, BRA 30333, BRA 30872, BRA 31496, BRA 31534, BRA 31828, BRA 31801 e BRA 13251). A cultivar de Arachis pintoi cv. Amarillo (BRA 13251) foi utilizada como testemunha. As... |
