Genome-Wide Association Mapping Identifies Novel Loci for Quantitative Resistance to Blackleg Disease in Canola

Frontiers in Plant Science, 2020
Blackleg disease, caused by the fungal pathogen Leptosphaeria maculans, continues to be a major concern for sustainable production of canola (Brassica napus L.) in many parts of the world.

Genetic Relationship of Brassicaceae Hybrids with Various Resistance to Blackleg Is Disclosed by the Use of Molecular Markers

Current Issues in Molecular Biology, 2022
Brassica napus is an important oil source. Its narrow gene pool can be widened by interspecific hybridization with the Brassicaceae species. One of the agronomically important traits, that can be transferred through the hybridization, is the resistance ...

Evolution of linked avirulence effectors in Leptosphaeria maculans is affected by genomic environment and exposure to resistance genes in host plants. [PDF]

PLoS Pathogens, 2010
Brassica napus (canola) cultivars and isolates of the blackleg fungus, Leptosphaeria maculans interact in a 'gene for gene' manner whereby plant resistance (R) genes are complementary to pathogen avirulence (Avr) genes.

Expression Profiling and Interaction Effects of Three R-Genes Conferring Resistance to Blackleg Disease in Brassica napus

Applied Sciences
Brassica napus L. is one of the world’s most important oilseed crops. Blackleg disease is a serious, yield-limiting factor in the cultivation of oilseed rape. Genetic resistance is primarily conferred by major resistance (R) genes.

From Recognition to Response: Resistance–Effector Gene Interactions in the Brassica napus and Leptosphaeria maculans Patho-System [PDF]

Plants
Blackleg disease, caused by the hemibiotrophic fungal pathogen Leptosphaeria maculans, poses a serious threat to Brassica crops and requires a broad understanding of the plant defence mechanisms. The Brassica. napus-L.

Selection and validation of stable reference genes in potato infected by Pectobacterium atrosepticum using real-time quantitative PCR [PDF]

Scientific Reports
Potato blackleg disease is caused by Pectobacterium atrosepticum, can seriously destroy potatoes’ growth and development. To accurately evaluate the expression levels of genes involved in potato (Solanum tuberosum) responses to P. atrosepticum infection,

Metabolomic Profiling Identifies Key Metabolites and Defense Pathways in <i>Rlm1</i>-Mediated Blackleg Resistance in Canola. [PDF]

Int J Mol Sci
Blackleg disease poses a major threat to global canola production. The resistance gene Rlm1, corresponding to the avirulence gene AvrLm1 in the pathogen Leptosphaeria maculans, has been widely used to mitigate the impact of the disease.

Genetic Analysis of a Horizontal Resistance Locus BLMR2 in Brassica napus

Frontiers in Plant Science, 2021
Leptosphaeria maculans causes blackleg disease in Brassica napus. The blackleg disease is mainly controlled by resistance genes in B. napus. Previous studies have shown that the blackleg resistant BLMR2 locus that conferred horizontal resistance under ...

Identification of candidate genes for LepR1 resistance against Leptosphaeria maculans in Brassica napus

Frontiers in Plant Science, 2023
Utilising resistance (R) genes, such as LepR1, against Leptosphaeria maculans, the causal agent of blackleg in canola (Brassica napus), could help manage the disease in the field and increase crop yield.

Identification of resistance loci in Chinese and Canadian canola/rapeseed varieties against Leptosphaeria maculans based on genome-wide association studies

BMC Genomics, 2020
Background The fungal pathogen Leptosphaeria maculans (Lm). causes blackleg disease on canola/rapeseed in many parts of the world. It is important to use resistant cultivars to manage the disease and minimize yield losses.
