Description

Ustiloxin D is a potent cyclic peptide mycotoxin produced by the rice false smut fungus *Ustilaginoidea virens*. This compound is of significant interest in biochemical and agricultural research due to its specific phytotoxic activity and role in plant-pathogen interactions. It serves as a critical reference standard and research tool for scientists in agrochemical development, plant pathology, and mycotoxin analysis.

Application

• Phytotoxicity and Mode-of-Action Studies: Used as a pure standard to investigate its effects on plant cell growth and division.
• Agricultural Research: Essential for studying the pathogenesis of rice false smut and developing potential control strategies.
• Analytical Reference Standard: Serves as a high-purity calibrant for the accurate quantification of Ustiloxin D in complex matrices like grains and plant tissues using HPLC or LC-MS/MS.
• Biochemical Research: Employed in studies exploring the biosynthesis pathway of ustiloxins and their interaction with tubulin, inhibiting microtubule assembly.
• Toxicology and Safety Assessment: Used in research to understand the toxicological profile and potential risks associated with this mycotoxin.
• Method Development and Validation: Critical for developing and validating sensitive analytical methods for mycotoxin detection in food and feed safety programs.
