The potential role of apoptosis in the host-parasite interaction of Leptosphaeria maculans with Brassica napus
The fungus Leptosphaeria maculans (Phoma or blackleg disease) causes lesions on leaf, stem and crown tissue of oilseed rape (Brassica napus). It is similar to many other necrotrophic fungi that rely on plant cell death for growth and reproduction. Recent published evidence supports the theory that some, if not all, necrotrophic bacteria and fungi stimulate apoptosis as a prerequisite for infect...
متن کاملDynamics of infection by Leptosphaeria maculans on canola (Brassica napus) as influenced by crop rotation and tillage
This study, intending to understand the effects of crop rotation and tillage on blackleg disease, was conducted in a field at Carman, Manitoba, Canada, from 1999 – 2002. Canola, wheat and flax were among the rotated crops. Rotations were performed under conventional or zero-till conditions. The number of infected plants, infected leaves per plant, lesions per plant, and percentage of leaf cover...
متن کاملIsocitrate lyase is essential for pathogenicity of the fungus Leptosphaeria maculans to canola (Brassica napus).
A pathogenicity gene has been identified in Leptosphaeria maculans, the ascomycetous fungus that causes blackleg disease of canola (Brassica napus). This gene encodes isocitrate lyase, a component of the glyoxylate cycle, and is essential for the successful colonization of B. napus. It was identified by a reverse genetics approach whereby a plasmid conferring hygromycin resistance was inserted ...
متن کاملInduced Resistance to Blackleg (Leptosphaeria maculans) Disease of Canola (Brassica napus) Caused by a Weakly Virulent Isolate of Leptosphaeria biglobosa
Canola (Brassica napus L.) is the second largest cash crop in Canada (4). Blackleg disease, caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph = Phoma lingam (Tode:Fr.) Desmaz.), is one of most economically important diseases of canola (21). In the past decade, canola production has expanded significantly worldwide and interest in the blackleg fungus, particularly its biology, ...
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)...
