Evolution of decreased sensitivity to azole fungicides in western European populations of Plenodomus lingam (Phoma stem canker on oilseed rape)

Plant Pathology, Volume 73, Issue 6, Page 1517-1532, August 2024.
Plenodomus lingam (Phoma leaf spot/stem canker) populations in western Europe (Germany, Ireland and the United Kingdom) predominantly contain CYP51 promoter inserts leading to deceased azole (DMI) fungicide sensitivity. Abstract Plenodomus lingam (Leptosphaeria maculans) and P. biglobosus (L. biglobosa) are fungi causing Phoma leaf spot/stem canker, an

No safe haven: Loss of avirulence in the plant pathogen Leptosphaeria maculans by DNA duplication and repeat‐induced point mutation

Plant Pathology, Volume 73, Issue 5, Page 1127-1135, June 2024.
Unlike other avirulence genes in canola pathogen Leptosphaeria maculans, AvrLm2 is protected from repeat‐induced point mutation (RIP): here fungal populations were identified with RIP in AvrLm2, due to a DNA duplication event. Abstract Microbes can overcome the ability of plant resistance genes to confer protection against disease by mutating their ...

Integrative transcriptomic and proteomic analysis reveals the regulatory mechanisms underlying oilseed rape resistance to Leptosphaeria biglobosa

Frontiers in Plant Science
Blackleg disease caused by Leptosphaeria species is a major constraint to rapeseed (Brassica napus) production worldwide. Although resistance to L. maculans is well studied, molecular and temporal responses of B. napus to L.

Effective control of Leptosphaeria maculans increases importance of L. biglobosa as a cause of phoma stem canker epidemics on oilseed rape

Pest Management Science, Volume 80, Issue 5, Page 2405-2415, May 2024.
Phoma stem canker caused by L. maculans and L. biglobosa, use of resistance genes and fungicides to control L. maculans increased infection by L. biglobosa in both upper stem lesions and stem base cankers. Effective control of phoma stem canker epidemics needs to target both L. maculans and L. biglobosa.

Leptosphaeria biglobosa inhibits the production of sirodesmin PL by L. maculans

Pest Management Science, Volume 80, Issue 5, Page 2416-2425, May 2024.
For the first time, L. biglobosa has been shown to inhibit the production of sirodesmin PL by L. maculans when interacting simultaneously with L. maculans either in vitro or in planta. This antagonistic effect of interspecific interaction may affect their coexistence and subsequent disease progression and management.

First Report of Leptosphaeria biglobosa as a Stem Canker Pathogen of Brassicas in New Zealand

Plant Disease, 2013
Phoma black leg or stem canker, caused by Leptosphaeria maculans or L. biglobosa, is an important disease of brassicas, causing significant crop losses in areas such as Europe, Australia, and North America (1). Samples collected in 2011 from canola and forage brassica (swede, kale, and turnip) crops in the main New Zealand growing regions (Southland ...

Overexpression of BnNAC19 in Brassica napus enhances resistance to Leptosphaeria maculans, the blackleg pathogen of canola

Plant Pathology, Volume 73, Issue 1, Page 104-114, January 2024.
Overexpression of BnNAC19 in canola (Brassica napus) can enhance disease resistance against blackleg, caused by Leptosphaeria maculans, providing a valuable genetic resource for disease breeding. Abstract Leptosphaeria maculans is a fungal pathogen that causes blackleg disease in canola (Brassica napus), resulting in significant yield and economic ...

Analysis of Alternative Splicing Events and Identification of Key Genes in Brassica napus Leaves Infected by Leptosphaeria biglobosa

Agronomy
Alternative splicing (AS) is a prevalent post-transcriptional regulatory mechanism in eukaryotes and plays a crucial role in plant disease resistance. Here, we used the Illumina Novaseq sequencing platform to conduct transcriptome sequencing on canola ...

In silico prediction and analysis of transmembrane‐coiled‐coil resistance gene analogues in 27 Brassicaceae species

Plant Pathology, Volume 73, Issue 1, Page 115-130, January 2024.
A total of 6788 transmembrane‐coiled‐coil (TM‐CCs) genes identified across 28 Brassicaceae species may play roles in plant defence and help improve crop disease resistance. Abstract The Brassicaceae family is composed of a broad range of species, including the economically important crops from Brassica, Raphanus, Camelina and Sinapis genera.

A new set of international Leptosphaeria maculans isolates as a resource for elucidation of the basis and evolution of blackleg disease on Brassica napus

Plant Pathology, Volume 73, Issue 1, Page 170-185, January 2024.
An international collection of Leptosphaeria maculans isolates has been established as a key resource to help understand the interaction between this fungal pathogen and its host, canola (Brassica napus). Abstract A collection of isolates of the fungi Leptosphaeria maculans and L.
