An international research team has identified two genes which could help protect barley against powdery mildew attack.

Led by the University of Adelaide in Australia and the Leibniz-Institute of Plant Genetics and Crop Plant Research (IPK) in Germany, the research will give plant-breeders new targets for developing lines of barley with resistance to powdery mildew.

Published in two separate papers in the journal New Phytologist, the researchers showed that by ‘silencing’ , the two genes ─ HvGsl6 and HvCslD2 which were shown to be associated with accumulation of callose and cellulose respectively, play an important role in blocking the penetration of the plant cell wall by the powdery mildew fungus.

Find out more via the two papers:

  1. The barley (Hordeum vulgare) cellulose synthase-like D2 gene (HvCslD2) mediates penetration resistance to host-adapted and nonhost isolates of the powdery mildew fungus
  2. Down-regulation of the glucan synthase-like 6 gene (HvGsl6) in barley leads to decreased callose accumulation and increased cell wall penetration by Blumeria graminis f. sp. hordei
