چکیده

Abstract Powdery mildew disease caused by Oidium arachidis poses a threat to peanut production in Africa. Loss of function mutants specific Mlo (Mildew Locus O) genes have provided broad-spectrum and durable resistance against pathogen many crop species. Since there is huge potential utilize susceptibility gene-mediated improvement, genome-wide mining required for further researches. However, the not been characterized genome. In this research study, genome cultivated was used as reference identify AhMlo loci. Our results revealed that 25 loci were identified distributed on chromosomes peanut. Eleven located A-genome while remaining 14 B-genome. Variable number inserted intron sequences (4–14) transmembrane helix (4–8) observed coding sequence Furthermore, phylogenetic analysis along with homologs from other species has clustered into six clades. Three clade V known regroup powdery dicots. Additionally, four core promoters predicted promoter region cis -regulatory elements related PM susceptibility. These strong evidence identification distribution can be loss study.

The Proteins of the Peanut, Arachis Hypogaea.

The ravages of the boll weevil have made it unprofitable to grow cotton in various sections throughout the South. In many regions where the growing of cotton has been decreased, peanuts are now being grown as a supplementary crop. This has caused a large increase in the production of peanuts in the United States. A number of mills which in the past produced cottonseed oil are now using their pr...

Cloning and characterization of SPL-family genes in the peanut (Arachis hypogaea L.).

SQUAMOSA promoter-binding protein-like (SPL) proteins play crucial roles in plant growth, development, and responses to environmental stressors. The peanut (Arachis hypogaea L.) is a globally important oil crop. In this study, we cloned the full-length cDNA of 15 SPLs in the peanut by transcriptome sequencing and rapid amplification of cDNA ends, and analyzed their genomic DNA sequences. cDNA l...

Cloning and Functional Analysis of Three Diacylglycerol Acyltransferase Genes from Peanut (Arachis hypogaea L.)

Diacylglycerol acyltransferase (DGAT) catalyzes the final and only committed acylation step in the synthesis of triacylglycerols. In this study, three novel AhDGATs genes were identified and isolated from peanut. Quantitative real-time RT-PCR analysis indicated that the AhDGAT1-2 transcript was more abundant in roots, seeds, and cotyledons, whereas the transcript abundances of AhDGAT1-1 and AhD...
