Root Transcriptome Analysis of Wild Peanut Reveals Candidate Genes for Nematode Resistance
Wild peanut relatives (Arachis spp.) are genetically diverse and were adapted to a range of environments during the evolution course, constituting an important source of allele diversity for resistance to biotic and abiotic stresses. The wild diploid A. stenosperma harbors high levels of resistance to a variety of pathogens, including the root-knot nematode (RKN) Meloidogyne arenaria, through t...
متن کاملComparative analysis of NBS-LRR genes and their response to Aspergillus flavus in Arachis
Studies have demonstrated that nucleotide-binding site-leucine-rich repeat (NBS-LRR) genes respond to pathogen attack in plants. Characterization of NBS-LRR genes in peanut is not well documented. The newly released whole genome sequences of Arachis duranensis and Arachis ipaënsis have allowed a global analysis of this important gene family in peanut to be conducted. In this study, we identifie...
متن کاملQTL mapping and transcriptome analysis of cowpea reveals candidate genes for root-knot nematode resistance
Cowpea is one of the most important food and forage legumes in drier regions of the tropics and subtropics. However, cowpea yield worldwide is markedly below the known potential due to abiotic and biotic stresses, including parasitism by root-knot nematodes (Meloidogyne spp., RKN). Two resistance genes with dominant effect, Rk and Rk2, have been reported to provide resistance against RKN in cow...
متن کاملComparative analysis of NBS domain sequences of NBS-LRR disease resistance genes from sunflower, lettuce, and chicory.
Plant resistance to many types of pathogens and pests can be achieved by the presence of disease resistance (R) genes. The nucleotide binding site-leucine rich repeat (NBS-LRR) class of R-genes is the most commonly isolated class of R-genes and makes up a super-family, which is often arranged in the genome as large multi-gene clusters. The NBS domain of these genes can be targeted by polymerase...
متن کاملSurvey and characterization of NBS-LRR (R) genes in Curcuma longa transcriptome
Resistance genes are among the most important gene classes for plant breeding purposes being responsible for activation of plant defense mechanisms. Among them, the nucleotide binding site-leucine rich repeat (NBS-LRR) class R-genes are the most abundant and actively found in all types of plants. Insilico characterization of EST database resulted in the detection of 28 NBS types R-gene sequence...
