Effect of jasmonic, salicylic, and abscisic acids on [(14)C]leucine incorporation into proteins of pea leaves.
All investigated exogenous phytohormones (jasmonic, salicylic, and abscisic acids) induced the appearance of (14)C-label in a polypeptide with molecular mass 29 kD that was not found in the control; these acids also increased [(14)C]leucine incorporation into a 25-kD polypeptide and decreased such incorporation into a 45-kD polypeptide. This can be considered as a nonspecific response of the plants to the action of these hormones. Salicylic and abscisic (but not jasmonic) acids induced the synthesis of a 19-kD polypeptide, and jasmonate induced the synthesis of a 96-kD polypeptide.
