Histone acetylation is a critical epigenetic modification that regulates plant immunity. Fungal pathogens secrete effectors modulate host immunity and facilitate infection, but whether fungal have evolved directly target histone remains unknown. Here, we identified secreted protein, UvSec117, from the rice false smut fungus, Ustilaginoidea virens, as key effector can deacetylase OsHDA701 negatively broad-spectrum resistance against pathogens. UvSec117 disrupts by recruiting to nucleus...
As with the majority of hemibiotrophic fungal pathogens, rice blast fungus Magnaporthe oryzae uses highly specialized infection structures called appressoria for plant penetration. Appressoria differentiated from germ tubes rely on enormous turgor pressure to directly penetrate cell, in which process lipid metabolism plays a critical role. In this study, we characterized MoPAH1 gene M. oryzae, encoding putative conserved phosphatidate phosphatase. The expression was up-regulated during...
Plant diseases cause enormous economic losses in agriculture and threaten global food security, application of agrochemicals is an important means to control crop diseases. Thus, exploring disease-resistant mechanisms synthesis highly bioactive are great importance. Here, we showed that propranolol, a phosphatidate phosphatase (Pah) inhibitor, effectively suppressed fungal growth, sporulation, sexual reproduction, plant infection on diverse plants. The MoPah1 enzyme activity the rice blast...
Abstract Serine protease subtilase, found widely in both eukaryotes and prokaryotes, participates various biological processes. However, how fungal subtilase regulates plant immunity is a major concern. Here, we identified secreted UvPr1a, from the rice false smut (RFS) fungus Ustilaginoidea virens. We characterized UvPr1a as virulence effector localized to cytoplasm that inhibits cell death induced by Bax. Heterologous expression of (Oryza sativa) enhanced susceptibility pathogens....
Abstract The Ubp family of deubiquitinating enzymes has been found to play important roles in plant‐pathogenic fungi, but their regulatory mechanisms are still largely unknown. In this study, we revealed the mechanism enzyme Ubp3 during infection process Magnaporthe oryzae . A UBP3 deletion mutant was severely defective appressorium turgor accumulation, leading impairment appressorial penetration. During formation, also glycogen and lipid metabolism. Interestingly, that nitrogen starvation...
Plant pathogens cause devastating diseases, leading to serious losses agriculture. Mechanistic understanding of pathogenesis plant lays the foundation for development fungicides disease control. Mitophagy, a specific form autophagy, is important fungal virulence. The role cardiolipin, mitochondrial signature phospholipid, in mitophagy and largely unknown pathogenic fungi. functions enzymes involved cardiolipin biosynthesis relevant inhibitors were assessed using set assays, including genetic...
Phosphatidic acid (PA) is considered as a second messenger that interacts with protein kinases, phosphatases and NADPH oxidases, amplifying the signal to initiate plant defense signaling responses (Li Wang, 2019). In rice, mutation of RBL1 causes accumulation PA, enhancing multipathogen resistance (Sha et al., 2023). our previous study, we attempted rescue rbl1 mutant by overexpressing phosphatidate phosphohydrolase ( PAH ) genes. However, overexpression PAH2 reduced PA level but did not...

Abstract Fusarium ear rot (FER) and stalk (FSR) caused by the filamentous fungus verticillioides have become increasingly serious around world. Additionally, fumonisins produced F. threaten food feed security. By adding contribution of genomic resources to better understand pathosystem including mechanisms –maize interactions, further improving quality genome, gap-free nuclear genome mitochondrial strain HN2 were sequenced assembled. Using Oxford Nanopore long reads next-generation...
