We found that TOR kinase regulates the plant environmental stress responses through phosphorylation at a conserved serine residue of Abscisic acid receptor PYR1/PYLs/RCARs. The phosphorylation inhibits the function of PYLs and prevents the binding of PYLs to abscisic acid and its downstream substrat...
