Article Synopsis
- Leptosphaeria maculans causes blackleg disease in Brassica napus, leading to significant yield losses, with the toxin Sirodesmin PL playing a key role in this process.
- The study focuses on how Sirodesmin PL affects gene expression, plant defenses, and cellular structures in B. napus cotyledons, showing that it upregulates defense-related genes while downregulating photosynthesis-related genes.
- The results indicate that Sirodesmin PL not only triggers defense mechanisms like reactive oxygen species production but also induces cell death through damage to the photosystem II, suggesting its role as a virulence factor for effective infection during the fungus's necrotrophic stage.
Article Synopsis
- Mutations are crucial for gene research across all forms of life, especially for identifying genes linked to asexual spore development in fungi.
- Researchers isolated mutants of the fungus Paecilomyces variotii, which cannot produce the yellow pigment due to mutations in specific genes (pvpP, abaA, and wetA) that are essential for pigment and spore development.
- The WetA protein, which is crucial for spore development, localizes in the nuclei of spores and functions as a transcription regulator, with differences in the impact of the related gene module among various fungal species.
Stipitate Thelephorales are basidiomycetous, mostly hydnoid, ectomycorrhizal fungi. Some species have declined considerably, and some are threat-listed as vulnerable or endangered. These ecological concerns require a well-resolved taxonomy to understand diversity in this group of fungi and facilitate conservation.

Growers increasingly rely on chemical and genetic options, but their relative benefits in disease control, yield, and economic outcomes are rarely quantified. We explore this relationship for blackleg crown canker disease (caused by ), a major biotic constraint limiting canola production globally.

However, other chemicals are used during canola cultivation, including fertilizers and herbicides. There is widespread use of herbicides that target the acetolactate synthase (ALS) enzyme involved in branched chain amino acid synthesis and low levels of these amino acids within leaves of Brassica species.
