Powdery Mildew Pathogen

Hosts and pathogens typically engage in an evolutionary arms race. This also applies to phytopathogenic powdery mildew fungi, which can rapidly overcome plant resistance and perform host jumps. Using experimental evolution, we show that the powdery mildew pathogen Blumeria graminis f.sp. hordei is capable of breaking the agriculturally important broad-spectrum resistance conditioned by barley loss-of-function mlo mutants. Partial mlo virulence is associated with a distinctive pattern of adaptive mutations, including small-sized (8-40 kb) deletions, one of which likely affects spore morphology. The detected mutational spectrum comprises the same loci in at least two independent mlo-virulent isolates, indicating convergent multigenic evolution. This work highlights the dynamic genome evolution of an obligate biotrophic plant pathogen with a transposon-enriched genome.

The knowledge about the nature and number of gene(s) controlling resistance is the pre-requisite for the success of powdery mildew resistance breeding program in pea. Seven biparental cross combinations involving three highly resistant (It-96, No. 267 and JI 2302) and two highly susceptible (Climax and PF-400) pea genotypes were evaluated for their response to powdery mildew disease. The quantitative microscopic scale of disease assessment coupled with detached leaf assay was employed for the evaluation of disease response of the crosses and their generations (F1, F2, BCs, and BCr) against two highly virulent conidial isolates of Erysiphe pisi. The disease response of 677 F2 plants has revealed a typical monohybrid Mendelian 3 (susceptible): 1 (resistant) segregation, moreover, the evaluation of 254 BCr plants gave a perfect 1 (susceptible): 1(resistant) segregation. No complementation was observed among all the F1 plants of three complementation crosses, suggesting that the same allele (er-1) conditions complete and broad-spectrum resistance in all the powdery mildew resistant pea genotypes in homozygous recessive form.
