Transcriptional Profiling and Genetic Mapping of Barley Responses to Bacterial Flagellin.

Diverse plant species detect bacterial flagellin using leucine-rich repeat receptor-like kinases (LRR RLKs) to activate defense responses and promote resistance against bacterial invasion. In barley, the impact of flagellin on inducible defense responses has not been fully described. Here, we report that the flagellin-derived flg22 peptide induces callose, ROS bursts and differential expression of 2603 genes in barley.
