摘要

保卫细胞中的淀粉代谢在调节气孔运动以应对光照、高浓度环境 CO2 以及潜在的其他非生物和生物因素方面起着核心作用。在这里，我们讨论了各种保卫细胞信号传导途径如何汇聚在一起，促进保卫细胞淀粉代谢的重新排列，以实现高效的气孔反应，这是维持植物生产力和抗逆性的重要生理过程。我们认为，操纵保卫细胞淀粉动态是一种以前被忽视的策略，可以改善气孔在不断变化的环境条件下的表现。

Starch metabolism in guard cells: At the intersection of environmental stimuli and stomatal movement.

Starch metabolism in guard cells plays a central role in regulating stomatal movement in response to light, elevated ambient CO2 and potentially other abiotic and biotic factors. Here, we discuss how various guard cell signal transduction pathways converge to promote rearrangements in guard cell starch metabolism for efficient stomatal responses, an essential physiological process that sustains plant productivity and stress tolerance. We suggest manipulation of guard cell starch dynamics as a previously overlooked strategy to improve stomatal behavior under changing environmental conditions.
