Plant Osmotic Stress Signaling: MAPKKKs Meet SnRK2s.

[EN] Osmotic stress signaling in higher plants is crucial to cope with abiotic stress. RAF-like MAPKKKs are activated by hyperosmotic stress and activate downstream ABA-unresponsive and ABA-activated SnRK2s, integrating early osmotic stress and ABA signaling cascades. The connection of B2/B3/B4 RAF-like MAPKKKs with SnRK2s is a new paradigm in signal transduction.We acknowledge SP20180340 (PAID-06-18) grant from UPV to J.L.-J. and BIO2017-82503-R grant from MICINN/FEDER and DSFP grant from KSU to P.L.RLozano Juste, J.; Alrefaei, AF.; Rodríguez Egea, PL.
