Stunning talk by Dr. Stella Cesari (PHIM, Univ. Montpellier):
MAX effectors—structurally conserved but sequentially diverse.
Beyond HIPPs, AVR-Pib hits MAPKKKs—key players in plant immunity.

One fold, many targets?

Plant Osmotic Stress Signaling: MAPKKKs Meet SnRK2s 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.
