A Tonoplast Calcineurin B-Like Protein and Stomatal Movement
Blog, Plant Physiology, Plant Physiology: On The InsideAbscisic acid (ABA) promotes stomatal closure and inhibits light-induced stomatal opening. An early event in ABA signaling is an influx Ca2+ ions across the plasma membrane and an increase of cytoplasmic calcium ([Ca2+]cyt). ABA-induced stomatal closure involves an outward K+ flux and dynamic vacuolar…

Rapid and reversible root growth inhibition by TIR1 auxin signalling (Nature Plants)
Plant Science Research WeeklyAuxin mediates many of its effects through transcriptional changes via the well-known interaction between its co-receptors and transcriptional regulators (TIR1/AFB – Aux/IAA), but some auxin responses happen too quickly to be explained by transcriptional changes. Fendrych et al. demonstrate that root…
