Transcriptome-wide Association study identifies putative Elicitors/Suppressor of Puccinia graminis f. sp. tritici that Modulate Barley rpg4-mediated Stem Rust Resistance
Transcriptomic profiling was done on barley samples incoulated with different Puccinia graminis f. sp. tritici (Pgt) isolates of varying virulence profile on barley stem rust resistance gene rpg4/5 and Rpg1. Several differentally expressed host and pathogen genes were identified while comparing gene expression profiles between group of samples inoculated with isoaltes of varying virulence. Several variants with genes of pathogen were idnetified that are possibly associated with virulence to rpg4/5. Overall design: Suceptible barley cv. Harrignton were treated with 24 Pgt isolates, indivdually and samples were collected 5 days post inoculation.
