TranscriptomicsbHLH transcription factors facilitating K+ uptake during stomatal opening are repressed by abscisic acid through phosphorylation
Stomata open in response to light and close following exposure to abscisic acid (ABA). They regulate gas exchange between plants and atmosphere, allowing plants to adapt to changing environmental conditions. ABA binding to receptors initiates a signaling cascade that involves protein phosphorylation...

ProteomicsPhosphorylation of WDR48 by phototropins drives starch degradation to promote stomatal opening
Plant stomata open in response to blue light under a background of red light. Red light induces starch accumulation through guard cell photosynthesis, whereas blue light causes rapid starch degradation via the activation of plasma membrane H+-ATPase through phosphorylation of BLUS1 by phototropins, ...
