Chemical suppressors of mlo-mediated powdery mildew resistance
Loss-of-function of barley mildew locus o (Mlo) confers durable broad-spectrum penetration resistance to the barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh). Given the importance of mlo mutants in agriculture, surprisingly few molecular components have been identified to be required for this type of resistance in barley. With the aim to identify novel cellular factors cont...
متن کاملmlo-based powdery mildew immunity: silver bullet or simply non-host resistance?
SUMMARY Durability and effectiveness against all genetic variants of a microbial species are hallmarks of so-called plant 'non-host' resistance. Highly effective immunity of monocotyledonous barley against the fungal powdery mildew pathogen, which is conferred by loss-of-function mutant alleles of the barley Mlo locus, likewise is a durable and broad-spectrum type of resistance. Although this w...
متن کاملTempered mlo broad-spectrum resistance to barley powdery mildew in an Ethiopian landrace
Recessive mutations in the Mlo gene confer broad spectrum resistance in barley (Hordeum vulgare) to powdery mildew (Blumeria graminis f. sp. hordei), a widespread and damaging disease. However, all alleles discovered to date also display deleterious pleiotropic effects, including the naturally occurring mlo-11 mutant which is widely deployed in Europe. Recessive resistance was discovered in Eth...
متن کاملmlo‐based powdery mildew resistance in hexaploid bread wheat generated by a non‐transgenic TILLING approach
Wheat is one of the most widely grown cereal crops in the world and is an important food grain source for humans. However, wheat yields can be reduced by many abiotic and biotic stress factors, including powdery mildew disease caused by Blumeria graminis f.sp. tritici (Bgt). Generating resistant varieties is thus a major effort in plant breeding. Here, we took advantage of the non-transgenic Ta...
متن کاملIdentification of Genes Required for the Function of Non-Race-Specific mlo Resistance to Powdery Mildew in Barley.
Recessive alleles (mlo) of the Mlo locus in barley mediate a broad, non-race-specific resistance reaction to the powdery mildew fungus Erysiphe graminis f sp hordei. A mutational approach was used to identify genes that are required for the function of mlo. Six susceptible M2 individuals were isolated after inoculation with the fungal isolate K1 from chemically mutagenized seed carrying the mlo...
