Dear Editor,The plant hormone abscisic acid (ABA) goves drought stress management in plants.ABA signal transduction appears to be rather short.When under water stress conditions,the ABA level rises above a certain threshold and the phytohormone binds to its cytosolic RCAR/PYR/PYL-type receptor (Levchenko et al.,2005;Joshi-Saha et al.,2011).Following receptor activation,protein phosphatases of the clade-A PP2C type are inactivated,allowing SnRK protein kinases to phosphorylate their targets,such as bZIP transcription factors (Fujii et al.,2009 and references therein).
