DOI: 10.1007/s00284-017-1338-3
Abstract: An insertional mutant with reduced pathogenicity on Brassica napus was identified in the plant pathogenic fungus Leptosphaeria maculans. The transfer-DNA molecule from Agrobacterium tumefaciens inserted into a gene encoding a protein with similarity to Sit4-associated… read more here.

DOI: 10.1007/s13313-017-0507-y
Abstract: Stem base canker caused by Leptosphaeria maculans (SBC) has been reported to affect canola production worldwide. Ascospores infections produce leaf spots (LS) in early vegetative stages. From these initial spots, the fungus grows towards the… read more here.

DOI: 10.1016/j.resmic.2020.05.001
Abstract: Auxins are hormones that regulate growth and development in plants. Besides plants, various microorganisms also produce auxins. Here we investigate whether and how the phytopathogenic fungus Leptosphaeria maculans biosynthesizes auxins. We characterized the auxin profile… read more here.
