Barley doubled haploid (DH) lines, from a wide cross between landrace Eth069 and cv Baudin, are used to filter gene expression changes from heterogeneous backgrounds during powdery mildew.. Barley double haploid gene expression during powdery mildew infection

Barley powdery mildew is a globally significant disease, responsible for reduced grain yield and quality. A major effect adult plant resistance gene, RBgh2, was previously found in a landrace from Azerbaijan, and mapped to barley chromosome 7HS. To investigate the genetic basis for the resistance, genome-wide gene expression was compared between sets of heterogeneous doubled haploids.
