Long non-coding RNAs in wheat are related to its susceptibility to powdery mildew

Abstract

To identify genes involved in the susceptibility to powdery mildew in wheat, genechip hybridization experiments were performed applying interactions between resistant and susceptible wheat cultivars and powdery mildew. Ten genes were found to express exclusively in the susceptible host after inoculation. The single cell transient expression experiments revealed that the RNA interference (RNAi) of two expressed sequence tag (EST) sequences (accession No. BQ168479 and CA648596) could enhance host resistance by 22 and 15 %, respectively. Full-length cDNA cloning revealed that they represented long non-coding RNAs (lncRNAs) and markedly accumulated during the powdery mildew primary infection. © 2014 Springer Science+Business Media Dordrecht.
