Receptor-Like Kinase ZmRLK9 Functions as an Upstream ABA Signaling Factor Conferring Drought Resilience in Maize.
The phytohormone abscisic acid (ABA) plays a pivotal role in plant drought responses. Although a substantial amount of research has concentrated on intracellular ABA receptors and SnRK2 protein kinases as the central signaling components, how the extracellular ABA signal is transduced to this core pathway remains large...
