Description

Tentoxin CAS NO 28540-82-1 is a cyclic tetrapeptide mycotoxin produced by certain plant-pathogenic fungi. This compound is of significant interest in biochemical and agricultural research due to its specific mode of action as a potent, non-phytotoxic inhibitor of chloroplast development. It serves as a critical tool for researchers and agrochemical developers studying plant physiology, herbicide mechanisms, and the discovery of novel plant growth regulators. Key industries that utilize this compound include agricultural biotechnology, academic research institutions, and companies focused on crop protection and plant science.

Application

• Biochemical Research: Used as a specific inhibitor of the chloroplast F1-ATPase (CF1-ATPase), enabling studies on photosynthetic mechanisms and energy transduction in plants.
• Plant Physiology Studies: Employed to induce chlorosis (bleaching) in sensitive plant seedlings, facilitating research on chloroplast biogenesis, protein import, and gene expression.
• Herbicide Mode-of-Action Research: Serves as a reference compound for investigating and comparing the effects of other bleaching herbicides that target photosynthetic apparatus.
• Agrochemical Discovery: Acts as a lead structure or a biological tool in screening programs aimed at developing new plant growth regulators or selective herbicides.
• Plant-Pathogen Interaction Studies: Used to explore the role of phytotoxins in fungal virulence and host-specificity in plant diseases.
