Abstract

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.

摘要

保卫细胞的淀粉代谢在响应光照、升高的环境 CO2 和潜在的其他非生物和生物因素调节气孔运动中起着核心作用。在这里，我们讨论了各种保卫细胞信号转导途径如何汇聚，以促进保卫细胞淀粉代谢的重新排列，从而实现有效的气孔响应，这是维持植物生产力和胁迫耐受性的重要生理过程。我们建议操纵保卫细胞淀粉动态作为一种以前被忽视的策略，以改善在不断变化的环境条件下的气孔行为。
