The abscisic acid (ABA) regulates plant growth and development as well as confers tolerance to abiotic and biotic stresses. However, the ABA pathways that orchestrate plant growth especially floral transition under environmental stresses are poorly explored. Recently, we found that SnRK2s, core components of ABA signalling, are desensitized by HOS15, a novel E3 ligase component. Besides their positive roles in stress adaptation, SnRK2s negatively regulate plant developmental processes including flowering time through activation of ABI5-FLC module which delays floral transition... ABI2, one of the major ABA signalling phosphatases, promotes floral transition as the knockout plants (abi2-2) show significantly late flowering. Previously, we have shown that ABI2 impairs SnRK2.6 stability, suggesting that ABI2 regulates flowering time by directly interacting with and dephosphorylating SnRK2s and ABI5 and thereby suppressing FLC indirectly...
