Description

Tabtoxin is a phytotoxic dipeptide produced by certain strains of *Pseudomonas syringae*, functioning as a potent non-host-specific toxin. Its primary value lies in its role as a key virulence factor in plant pathology research and as a tool compound for studying amino acid biosynthesis inhibition in plants. This product is essential for researchers and developers in the agricultural biotechnology and plant science sectors, particularly for investigating plant-pathogen interactions, developing disease models, and exploring novel modes of action for plant protection strategies.

Application

• Plant Pathology Research: Used as a standard toxin to study bacterial blight diseases and the mechanisms of host susceptibility.
• Biochemical Studies: Serves as a specific inhibitor of glutamine synthetase, facilitating research into plant nitrogen metabolism and amino acid biosynthesis pathways.
• Phytotoxin Standard: Acts as a reference standard in analytical laboratories for the detection and quantification of bacterial toxins in plant tissues and environmental samples.
• Agrochemical Development: Employed in screening programs and mode-of-action studies to identify and characterize new targets for herbicide or bactericide discovery.
• Plant Defense Elicitation: Used in studies to understand and trigger plant defense responses against pathogen attack.
• Microbial Ecology: Applied in research investigating the ecological role of toxin-producing bacteria in plant microbiomes.
