Rapid identification of the Leptosphaeria maculans avirulence gene AvrLm2 using an intraspecific comparative genomics approach.
Five avirulence genes from Leptosphaeria maculans, the causal agent of blackleg of canola (Brassica napus), have been identified previously through map-based cloning. In this study, a comparative genomic approach was used to clone the previously mapped AvrLm2. Given the lack of a presence-absence gene polymorphism coincident with the AvrLm2 phenotype, 36 L. maculans isolates were resequenced an...
متن کاملBacterial avirulence genes.
Although more than 30 bacterial avirulence genes have been cloned and characterized, the function of the gene products in the elictitation of resistance is unknown in all cases but one. The product of avrD from Pseudomonas syringae pv. glycinea likely functions indirectly to elicit resistance in soybean, that is, evidence suggests the gene product is an enzyme involved in elicitor production. I...

متن کاملIdentification of the corresponding avirulence gene of Leptosphaeria maculans to the resistance gene (LepR1) in Brassica napus
Blackleg of canola is the most important disease of canola/rapeseed worldwide. Efforts are made to understand the host-pathogen interaction by studying the interaction between resistance genes of the host and the avirulence genes of the pathogen. Previous studies showed that two double haploid canola (Brassica napus L.) lines, ddm-12-65-1 and ddm-12-65-2, possess a novel resistance gene (LepR1)...
متن کاملProspects for understanding avirulence gene function.
Avirulence genes are originally defined by their negative impact on the ability of a pathogen to infect their host plant. Many avirulence genes are now known to represent a subset of virulence factors involved in the mediation of the host-pathogen interaction. Characterization of avirulence genes has revealed that they encode an amazing assortment of proteins and belong to several gene families...
