Histone Deacetylase UvHST2 Is a Global Regulator of Secondary Metabolism in Ustilaginoidea virens

Journal of Agricultural and Food Chemistry, 2023
Ustilaginoidea virens, the causal agent of rice false smut, produces a large amount of mycotoxins, including ustilaginoidins and sorbicillinoids. However, little is known about the regulatory mechanism of mycotoxin biosynthesis inU. virens.

Ustilaginoidin D induces hepatotoxicity and behaviour aberrations in zebrafish larvae

Toxicology, 2021
Ustilaginoidins, a group of bis-naphtho-γ-pyrones, are one of the major mycotoxins produced by Ustilaginoidea virens. This group of bis-naphtho-γ-pyrone mycotoxins has been demonstrated to have antibacterial and immunological inhibitory activities and strong cytotoxicity to human oral epidermoid carcinoma.

Effect of Chaetochromin A, Chaetochromin D and Ustilaginoidin A, Bis (naphtho‐γ‐pyrone) Derivatives, on the Mouse Embryo Limb Bud and Midbrain Cells in Culture

Congenital Anomalies, 1987
Abstract Mouse embryo limb bud (LB) and midbrain (MB) cells were prepared from day 10 mouse embryos and cultured as micromass cell islands for 5 days. Differentiation was determined by the number of stainable foci of differentiated cells, and the concentration at which each compound inhibited the formation of differentiated foci by 50% of the control ...
