The wheat leaf rust resistance gene Lr1 encodes a typical coiled-coil nucleotide-binding site leucine-rich repeat (CC-NBS-LRR) of protein containing 1 344 amino acids. WR003, cleaved amplified polymorphic sequence (CAPS) marker is derived from the LRR regions Lr1. In this study, worldwide collection 120 Aegilops tauschii accessions and 282 hexaploid varieties was screened for alleles using spec...

Race-specific disease resistance in plants typically requires the action of complementary genes in the pathogen and the host: a functional avirulence (Avr) gene in the pathogen and a corresponding resistance (R) gene in the host. There is solid evidence that Avr and R gene products influence disease resistance pathways in the host and that in the absence of a corresponding R gene, Avr proteins ...

Plant resistance genes (R-genes) drive the immune responses of crops against specific pathotypes disease-causing organisms. Over time, genetic diversity in R-genes and R-pseudogenes has arisen among different rice varieties. This bioinformatics study was carried out to (i) predict full sets candidate nucleotide-binding site leucine-rich repeat (NLR) present six genomes; (ii) detect variation wi...
