Resistance genes to Blumeria graminis and their products in cereals

Powdery mildew is one of the most destructive wheat diseases, and it causes a constant need for improvement resistance. Transfer resistance genes from wild relatives into genetic pool could be an alternative to use fungicides. This review contains classification powdery on different ontogenetic stages (seedling adult resistance), expression trait (quantitative qualitative), conferring (wide-spectrum race-specific resistance). are characterised; number identified constantly increasing, in 2019 / alleles was 89. The controlling desired have originated relatives, namely: rye (Secale cereale L.), Dasypyrum villosum (L.) P. Candargy (Haynaldia villosa Schur), Thinopyrum intermedium, species genera Aegilops Triticum. Resistance classified by their products, chromosome localization, presence alleles. For genes, localization nature protein products not yet been determined. Attention also focused possible complications that arise during identification new when already known falsely as ones. mostly receptors, which according domain structure. variable domains these proteins leucine-rich repeats (LRRs), provide specificity receptors. Interaction between pathogen effectors plant occurs through direct physical interaction or intermediate signalling events. described, based results experiments conducted other model plants, including monocots (rice), although information obtained Arabidopsis thaliana has analyzed.
