Coronatine is a polyketide phytotoxin produced by several members of the Pseudomonas syringae group of pathovars such as atropurpurea, glycinea, maculicola,morsprunorum andtomato. Coronatine was used to study the regulatory genes: corP, corS and corR. It was used to study the stimulation of ethylene synthesis in Nicotiana tabacum leaves.
Biochem/physiol Actions
Coronatine is a polyketide phytotoxin produced by several members of the Pseudomonas syringae group of pathovars. It consists of two distinct structural components that function as biosynthetic intermediates: coronafacic acid (CFA) and coronamic acid (CMA). It is known to induce hypertrophy and chlorosis, inhibit root elongation, and stimulate ethylene production.
