Molecular genetics of resistance to Puccinia hordei in barley

Abstract

Barley leaf rust, caused by Puccini hordei, stands as one of the most severe biotic threats to barley production. Deployment of genetic resistance is considered to be the most effective and ecologically sustainable way to control this disease. To have a better understanding of plant defense mechanism at molecular level, two barley leaf rust resistance genes were isolated in the present study. Additionally, the first chromosome-level haplotype-phased assembly of P. hordei was generated to underpin studies on host-pathogen interactions at the molecular level.
