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...
Summary Rice false smut caused by Ustilaginoidea virens is a devastating rice ( Oryza sativa) disease worldwide. However, the molecular mechanisms underlying U . –rice interactions are largely unknown. In this study, we identified secreted protein, Uv1809, as key virulence factor. Heterologous expression of Uv1809 in enhanced susceptibility to and bacterial blight. Host‐induced gene silencing resistance , suggesting that inhibits immunity promotes infection suppresses targeting enhancing...
The post-translational modification lysine 2-hydroxyisobutyrylation (Khib ) plays an important role in gene transcription, metabolism, and enzymatic activity. Khib sites have been identified rice (Oryza sativa). However, the status of proteins flowers during pathogen infection remains unclear. Here, we report a comprehensive identification -modified flowers, changes these with fungal Ustilaginoidea virens. By using tandem mass tag-based quantitative proteomics approach, 2,891 on 964 flowers....
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....
Rice false smut (RFS) caused by Ustilaginoidea virens is one of the most important disease in rice (Oryza sativa)-growing regions worldwide. RFS not only causes yield losses but also potentially threatens human and animal health producing cyclopeptide mycotoxins (Sun et al., 2020). Introducing genetically encoded resistance an environmentally friendly, economical approach to controlling plant diseases (Yu 2023). However, at present, varieties gene resources are still extremely scarce, it...
Rice false smut is a fungal disease distributed worldwide and caused by Ustilaginoidea virens. In this study, we identified putative ester cyclase (named as UvEC1) being significantly upregulated during U. virens infection. UvEC1 contained SnoaL-like polyketide domain, but the functions of ketone cyclases such SnoaL in plant pathogens remain unclear. Deletion defects vegetative growth conidiation. was also required for response to hyperosmotic oxidative stresses maintenance cell wall...
Lysine β-hydroxybutyrylation (Kbhb) is an evolutionarily conserved and widespread post-translational modification that associated with active gene transcription cellular proliferation. However, its role in phytopathogenic fungi remains unknown. Here, we characterized Kbhb the rice false smut fungus Ustilaginoidea virens. We identified 2204 sites 852 proteins, which are involved diverse biological processes. The mitogen-activated protein kinase UvSlt2 a protein, strain harboring point...
ABSTRACT S-palmitoylation is an important reversible protein post-translational modification in organisms. However, its role fungi uncertain. Here, we found the treatment of rice false fungus Ustilaginoidea virens with inhibitor 2 BP resulted a significant decrease fungal virulence. Comprehensive identification sites and proteins U. revealed total 4,089 identified among 2,192 that S-palmitoylated were involved diverse biological processes. Among five palmitoyltransferases, UvPfa3 UvPfa4 to...
Rice false smut caused by Ustilaginoidea virens is a serious disease of rice (Oryza sativa), severely reducing plant mass and yields worldwide. We performed genome-wide analysis the CCHC-type zinc-finger transcription factor family in this pathogen. identified functionally characterized seven UvCCHC genes U. virens. The deletion various affected stress responses, vegetative growth, conidiation, virulence ∆UvCCHC5 mutants infected spikelets normally but could not form balls. Sugar utilization...
Pathogen attack can increase plant levels of reactive oxygen species (ROS), which then act as signaling molecules activating defense. Elucidating these processes is crucial to understanding the redox pathways in defense responses. By an iodo TMT–based quantitative proteomic approach, we mapped 3,362 oxidized cysteine sites 2,275 proteins rice leaves. Oxidized were involved gene expression, peptide biosynthetic processes, stress responses, ROS metabolic and translation pathways. Magnaporthe...
Rice false smut (RFS), caused by Ustilaginoidea virens, has become a major disease in recent years, and mycotoxins produced U. virens often threaten food safety. To study fungal pathogenesis identify potential targets for developing new fungicides, gap-free nuclear complete mitochondrial genomes of JS60-2 were sequenced assembled. Using the second third generation sequencing data, we assembled 38.02-Mb genome that consists seven contigs with contig N50 being 6.32-Mb. In total, 8,486...
