Ectopic expression of constitutively activated RACB in barley enhances susceptibility to powdery mildew and abiotic stress.
Small RAC/ROP-family G proteins regulate development and stress responses in plants. Transient overexpression and RNA interference experiments suggested that the barley (Hordeum vulgare) RAC/ROP protein RACB is involved in susceptibility to the powdery mildew fungus Blumeria graminis f. sp. hordei. We created transgenic barley plants expressing the constitutively activated RACB mutant racb-G15V...
متن کاملNar-1 and Nar-2, Two Loci Required for Mla12-Specified Race-Specific Resistance to Powdery Mildew in Barley.
Previously isolated susceptible host mutants were used in a genetic and functional study of the resistance response of barley specified by resistance gene Mla12 to the fungal pathogen Erysiphe graminis f sp hordei. Mutant M66 represents a defective allele of Mla12, whereas M22, M82, and M100 represent mutations in loci unlinked to Mla12. Intermutant crosses of the latter three show that suscept...
متن کاملA small GTP-binding host protein is required for entry of powdery mildew fungus into epidermal cells of barley.
Small GTP-binding proteins such as those from the RAC family are cytosolic signal transduction proteins that often are involved in processing of extracellular stimuli. Plant RAC proteins are implicated in regulation of plant cell architecture, secondary wall formation, meristem signaling, and defense against pathogens. We isolated a RacB homolog from barley (Hordeum vulgare) to study its role i...
متن کاملA component of the Sec61 ER protein transporting pore is required for plant susceptibility to powdery mildew
Biotrophic pathogens, like the powdery mildew fungi, require living plant cells for their growth and reproduction. During infection, a specialized structure called the haustorium is formed by the fungus. The haustorium is surrounded by a plant cell-derived extrahaustorial membrane (EHM). Over the EHM, the fungus obtains nutrients from and secretes effector proteins into the plant cell. In the p...
متن کاملInduction of Disease Symptoms in Barley by Powdery Mildew.
Powdery millews usually grow superficially on their hosts but produce symptoms of disease throughout the underlying host tissues. The symptoms include marked increase in respiratory rate (1, 3, 15. 24, 26, 30. 35); accumulation of organic and inorganic substances (1,29, 36): increase in dry weight (10. 26) ; increase in wet weight (3) decrease in photosynthesis when the disease is well develope...
