Validation of CAPS marker WR003 for the leaf rust resistance gene Lr1 and the molecular evolution of Lr1 in wheat
The wheat leaf rust resistance gene Lr1 encodes a typical coiled-coil nucleotide-binding site leucine-rich repeat (CC-NBS-LRR) of resistance protein containing 1 344 amino acids.WR003, a cleaved amplified polymorphic sequence (CAPS) marker is derived from the LRR regions of Lr1.In this study, a worldwide collection of 120 Aegilops tauschii accessio
