TLDR
It is discovered that the Target of Rapamycin (TOR) kinase phosphorylates PYL ABA receptors at a conserved serine residue to prevent activation of the stress response in unstressed plants and utilizes this conserved phospho-regulatory feedback mechanism to optimize the balance of growth and stress responses.
