REGULATION METHOD OF ANTHOCYANIN BIOSYNTHESIS

摘要

PURPOSE: A method for controlling anthocyanin biosynthesis is provided to accumulate anthocyanin through controlling ethylene signal transduction pathway and have information of gene relating to anthocyanin biosynthesis. CONSTITUTION: A mutant of ethylene receptor gene is etr1-1, etr1-2, etr1-3, etr1-4, etr2-1 or ers2-1. The anthocyanin biosynthesis of Arabidopsis thaliana is regulated by irradiating light to mutant Arabidopsis thaliana in a medium containing sucrose, relating to ethylene signal transduction. The mutant gene relating to ethylene signal transduction is ein2-1. The light intensity is 140 μmolm^-2s^-1. The sucrose concentration is 60 mM.
