An eQTL analysis of partial resistance to Puccinia hordei in barley.

ABSTRACT:

Background

Genetic resistance to barley leaf rust caused by Puccinia hordei involves both R genes and quantitative trait loci. The R genes provide higher but less durable resistance than the quantitative trait loci. Consequently, exploring quantitative or partial resistance has become a favorable alternative for controlling disease. Four quantitative trait loci for partial resistance to leaf rust have been identified in the doubled haploid Steptoe (St)/Morex (Mx) mapping population. Further investigations are required to study the molecular mechanisms underpinning partial resistance and ultimately identify the causal genes.

Methodology/principal findings

We explored partial resistance to barley leaf rust using a genetical genomics approach. We recorded RNA transcript abundan
