蔗糖代谢及信号转导在植物发育和逆境响应中的作用

Role of Sucrose Metabolism and Signal Transduction in Plant Development and Stress Response

蔗糖代谢在植物发育、应激响应和产量形成中起关键作用。糖类的合成和分解推动植物整个生长发育过程,蔗糖作为信号因子参与调节相关基因表达,并能与其他基因、激素、以及防御信号发生互作;然而,蔗糖代谢和细胞内外信号传递之间的耦合以及蔗糖代谢酶发挥其信号转导作用的机制并不相同。本文综述了蔗糖代谢关键酶在植物发育和非生物胁迫响应中的作用,并结合当前研究现状,对糖代谢及其信号转导研究的未来方向提出建议,以更好地理解和改善植物的生长发育及抗逆特性。

Sucrose metabolism plays a critical role in plant development, stress response and yield formation. The growth and development process of the plant is promoted through the synthesis and decomposition of a series of sugars. As a signal factor, it participates in regulating the expression of related genes, and can interact with other genes, hormones, and defense signals. However, the coupling mechanism of sucrose metabolism and signal transmission between intracellular and external is different from the signal transduction mechanism of sucrose metabolizing enzymes. This article reviews the function of crucial sucrose metabolism enzymes in plant development and response to abiotic stresses. Combining with the current researches, the future research direction of sugar metabolism and its signal transduction has being proposed, which will contribute to understanding and improving the characteristics of plant growth and development as well as stress resistance.
