Outline of Final Research Achievements	ACC synthase, ACS, which is rate limiting key enzyme of plant hormone ethylene biosynthesis is phosphorylated by protein kinase CDPK and MAPK respectively. Phosphorylated ACS is stable and dephosphorylated one is unstable in cell. I identified B”type subunit as candidate that recognizes ACS as target.
