UvHOS3 ‐mediated histone deacetylation is essential for virulence and negatively regulates ustilaginoidin biosynthesis in Ustilaginoidea virens [PDF]
Molecular Plant PathologyUvHOS3 in Ustilaginoidea virens controls histone deacetylation at H3K9, H3K18, H3K27 and H4K8 and positively regulates fungal growth and pathogenicity, but negatively modulates mycotoxin biosynthesis. Abstract Ustilaginoidea virens is the causal agent of rice false smut, which has recently become one of the most important rice diseases worldwide ...

An Ustilaginoidea virens Nuclear Effector SCRE7 Inhibits Rice Immunity via Suppressing OsLBD11/12-Promoted Transcription of OsCPS2. [PDF]
Plant Biotechnol JABSTRACT Phytopathogenic fungi secrete a great number of effector proteins into various organelles of host plants and suppress plant immunity through different mechanisms. In this study, we identify SCRE7 as a unique nuclear effector that is essential for U. virens infection.
