A blueprint for making cereal crops more resistant to fungal disease
Powdery mildew is a destructive fungal disease of barley that can result in crop losses of up to 40%. To protect themselves from powdery mildew, barley has evolved a series of immune receptors that each recognize matching, strain-specific powdery mildew proteins known as effectors.
Discovery of wheat gene pair that combats powdery mildew could lead to more resistant varieties
A study has identified a wheat nucleotide-binding and leucine-rich repeat (NLR) gene pair, RXL and Pm5e, that confers resistance to the devastating wheat powdery mildew disease.
Researchers uncover natural variation in wild emmer wheat for broad-spectrum disease resistance
Bread wheat is one of the most important staple crops for millions of people and is apparently the largest cultivated and traded cereal worldwide. Bread wheat is a hexaploid species with three subgenomes (2n = 6x = 42, AABBDD) that has undergone two separate allopolyploidization and domestication events.
Manipulating host defenses: Unveiling the role of a powdery mildew effector in grapevine infection
Powdery mildew, caused by Erysiphe necator, is a significant threat to grapevine health, utilizing secreted effector proteins (CSEPs) to suppress plant defenses. Despite knowledge of plant immune mechanisms, the specific roles of E. necator's CSEPs in infection remain largely unknown.
Gene discovery takes aim at powdery mildew, a hemp nemesis
Cornell researchers have discovered a gene in hemp for resistance to powdery mildew—giving the fledgling hemp industry a new tool to combat one of the most prevalent diseases affecting the production of high-cannabinoid Cannabis sativa.
