Histone H4K8hib modification promotes gene expression and regulates rice immunity.

This study uncovers the role of H4K8hib as an active epigenetic mark in rice that positively correlates with gene expression and enhances immune responses. Furthermore, HDA705 was identified as the key enzyme regulating H4K8hib. Mutation of HDA705 led to hyper-H4K8hib, which in turn activated the expression of defense-related genes and enhanced rice resistance to pathogens.

S-palmitoylation of MAP kinase is essential for fungal virulence.

A secreted fungal laccase targets the receptor kinase OsSRF3 to inhibit OsBAK1-OsSRF3-mediated immunity in rice.

The identification effector targets and characterization of their functions are crucial for understanding pathogen infection mechanisms and components of plant immunity. Here, we identify the effector UgsL, a ustilaginoidin synthetase with a key role in regulating virulence of the rice false smut fungus Ustilaginoidea virens. Heterologous expression of UgsL in rice (Oryza sativa) enhances plant susceptibility to multiple pathogens, and host-induced gene silencing of UgsL enhances plant resistance to U.

Dysfunction of dendritic cells in tumor microenvironment and immunotherapy.

Dendritic cells (DCs) comprise diverse cell populations that play critical roles in antigen presentation and triggering immune responses in the body. However, several factors impair the immune function of DCs and may promote immune evasion in cancer. Understanding the mechanism of DC dysfunction and the diverse functions of heterogeneous DCs in the tumor microenvironment (TME) is critical for designing effective strategies for cancer immunotherapy.

Post-Translational Modification β-Hydroxybutyrylation Regulates Ustilaginoidea virens Virulence.

Lysine β-hydroxybutyrylation (K) is an evolutionarily conserved and widespread post-translational modification that is associated with active gene transcription and cellular proliferation. However, its role in phytopathogenic fungi remains unknown. Here, we characterized K in the rice false smut fungus Ustilaginoidea virens.

Comparative oxidation proteomics analyses suggest redox regulation of cytosolic translation in rice leaves upon Magnaporthe oryzae infection.

Pathogen attack can increase plant levels of reactive oxygen species (ROS), which act as signaling molecules to activate plant defense mechanisms. Elucidating these processes is crucial for understanding redox signaling pathways in plant defense responses. Using an iodo-tandem mass tag (TMT)-based quantitative proteomics approach, we mapped 3362 oxidized cysteine sites in 2275 proteins in rice leaves.

Gap-Free Nuclear and Mitochondrial Genomes of JS60-2, a Fungal Pathogen Causing Rice False Smut.

Rice false smut (RFS), caused by , has become a major disease in recent years, and mycotoxins produced by often threaten food safety. To study fungal pathogenesis and identify potential targets for developing new fungicides, gap-free nuclear and complete mitochondrial genomes of JS60-2 were sequenced and assembled. Using the second and third generation sequencing data, we assembled a 38.

A secreted fungal subtilase interferes with rice immunity via degradation of SUPPRESSOR OF G2 ALLELE OF skp1.

Serine protease subtilase, found widely in both eukaryotes and prokaryotes, participates in various biological processes. However, how fungal subtilase regulates plant immunity is a major concern. Here, we identified a secreted fungal subtilase, UvPr1a, from the rice false smut (RFS) fungus Ustilaginoidea virens.

A secreted fungal effector suppresses rice immunity through host histone hypoacetylation.

Histone acetylation is a critical epigenetic modification that regulates plant immunity. Fungal pathogens secrete effectors that modulate host immunity and facilitate infection, but whether fungal pathogens have evolved effectors that directly target plant histone acetylation remains unknown. Here, we identified a secreted protein, UvSec117, from the rice false smut fungus, Ustilaginoidea virens, as a key effector that can target the rice histone deacetylase OsHDA701 and negatively regulates rice broad-spectrum resistance against rice pathogens.
