General description

Thaxtomin A belongs to the class of 4-nitroindol-3-yl-containing 2,5 dioxopiperazines.

Biochem/physiol Actions

Cellulose synthesis inhibition by thaxtomin A, indicates plant-pathogen interaction. Along with this, it also results in hypocotyls swelling and decreased seedling growth. Thaxtomin A leads to common scab disease in potato. On the whole, it attenuates cell growth and induces cell death in the infected plant.
Thaxtomin A is a nitrated diketopiperazine phytotoxin produced by Streptomyces scabies that induces plant cells necrosis. Thaxtomin A is a potent plant cellulose synthesis inhibitor.
