Isocitrate 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 کاملThe 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 کاملGenetic Dissection of Blackleg Resistance Loci in Rapeseed (Brassica napus L.)
Blackleg disease caused by the heterothallic ascomycete fungus Leptosphaeria maculans (Desm.) Ces. et de Not. (anamorph: Phoma lingam Tode ex Fr.), is the major disease of Brassica crops such as turnip rape (Brassica rapa L. syn. B. campestris; 2n = 2x = 20, genome AA), cabbage (B. oleracea L.; 2n = 2x = 18, genome CC), rapeseed (syn. canola or oilseed rape B. napus L.; 2n = 4x = 38, genome AAC...
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 کاملDetection of Fungus Infection on Petals of Rapeseed (Brassica napus L.) Using NIR Hyperspectral Imaging
Infected petals are often regarded as the source for the spread of fungi Sclerotinia sclerotiorum in all growing process of rapeseed (Brassica napus L.) plants. This research aimed to detect fungal infection of rapeseed petals by applying hyperspectral imaging in the spectral region of 874-1734 nm coupled with chemometrics. Reflectance was extracted from regions of interest (ROIs) in the hypers...
