Summary: This study analyzes the role of CgHSF1 in the pathogenicity of Colletotrichum gloeosporioides and investigates the underlying mechanism. It is found that CgHSF1 is essential for the viability of the fungus and plays a role in pathogenicity through the transcriptional activation of melanin biosynthesis.

Summary: In this study, a histone deacetylase CgHOS2 was identified and characterized in Colletotrichum gloeosporioides. Knocking out CgHOS2 resulted in decreased vegetative growth, impaired conidiation, and reduced stress tolerance, leading to the loss of pathogenicity on intact plant leaves.

Summary: This study identified multiple novel factors contributing to the pathogenicity of S. turcica, including cytoskeleton regulators, glycosyl hydrolases, and a specific effector protein. These factors help the phytopathogen establish infection on maize at early stages, highlighting the sophisticated strategies employed by S. turcica for pathogenesis.

Summary: In this study, the function of the nucleosome assembly protein MoNap1 in Magnaporthe oryzae was investigated. MoNap1 plays an important role in pathogenicity by regulating cell wall, oxidation, and hyperosmotic stress. It interacts with MoNbp2, MoClb3, and MoClb1 and is involved in the regulation of the melanin biosynthetic process. The results demonstrate the crucial role of MoNap1 in the growth, conidiation, and pathogenicity of M. oryzae.

Summary: This study investigated the infection position of appressoria on maize leaves and found that the appressorium structure was necessary for infection, regardless of penetration through epidermal cells or stomata. It was also found that melanin synthesis, DNA replication, and autophagy had significant effects on the development of appressoria, turgor pressure, and glycerol content.

Summary: In this study, MoWhi2 and MoPsr1 were identified as key regulators in appressorium formation and pathogenicity of M. oryzae by controlling cAMP levels and activating the MoTor signaling pathway. The disruption of MoWHI2 resulted in the formation of multiple appressoria by one conidium and reduced pathogenicity, while the knockout mutant Delta Mopsr1 displayed similar phenotypes. The results suggest that the inappropriate activation of the MoTor signaling pathway is a crucial factor in the defects of appressorium formation in the Delta Mowhi2 and Delta Mopsr1 strains.

Summary: Colletotrichum scovillei, a phytopathogenic fungus causing significant yield losses on economic crops worldwide, remains poorly understood in terms of the underlying molecular mechanisms related to anthracnose development. Our study identified CsHOX1 as a novel pathogenicity factor suppressing host defense mechanisms, with CsHOX2 and CsHOX7 playing crucial roles in conidiation and appressorium development in a stage-specific manner in C. scovillei. This research provides a molecular foundation for understanding anthracnose development on fruits caused by C. scovillei, facilitating the development of novel disease management strategies.

Summary: Cut roses are valuable ornamentals, but their profitability is dependent on postharvest performance. Bent neck symptoms in roses, caused by physiological disorders, bacteria accumulation, and Botrytis cinerea infection, make them unmarketable. This research identified Sclerotinia sclerotiorum as the causal agent of rose bent neck symptoms. Considering S. sclerotiorum incidence is important to prevent outbreaks when observing bent neck symptoms.
