Barley (Hordeum vulgare) is affected by a number of biotic and abiotic stresses that lower quality and yield. The most important barley diseases include net blotch, spot blotch, scald, Ramularia leaf spot, crown rot, common root rot, barley stripe, leaf rust, stripe rust, stem rust, Fusarium head blight, bacterial leaf streak, cereal cyst nematodes and barley yellow dwarf virus. Utilizing genetic resistance is the preferred approach to controlling these diseases. Wild barley and barley landraces are important sources of resistance to diseases. Barley landraces are still grown by farmers in many parts of the world. Wild barley species, especially Hordeum spontaneum and Hordeum bulbosum, have been explored and in some cases exploited as disease-resistance sources. The widespread use of common barley cultivars has narrowed the genetic base available for resistance. The utilization of barley landraces and wild barley will enhance disease resistance studies. This Research Topic addresses disease resistance and resistance mechanisms in Hordeum species including Hordeum vulgare, Hordeum spontaneum, and Hordeum bulbosum.
The use of common barley cultivars has narrowed the genetic base available for resistance. Barley landraces and wild barley species offer promise for disease-resistant barley crops. Many loci conferring resistance to different pathogens have been identified. However, changes in virulence in pathogens with respect to these resistances remain an ongoing challenge. This Research Topic will address all aspects of barley plant-pathogen interactions and resistance studies.
Articles and review papers related to all aspects of resistance studies of Hordeum species to biotic diseases and abiotic factors will be considered. Wild barley and barley landraces are important resistance sources to diseases. Mechanisms of resistance and plant-pathogen interactions including race/pathogen determinations and elucidation of pathogenicity mechanisms will be welcomed.
