Photoreceptor-mediated Pathway and Regulation Mechanism of Potato Tuber Formation

摘要

光照是植物生长发育过程中必需的因素，各种光受体介导的光参与了多种植物生理活动。马铃薯块茎形成与光照紧密相关，光受体如何在分子层面上影响马铃薯块茎形成，一直是块茎发育研究的热点。以现有块茎发育机制作为理论基础，重点总结了光敏色素、隐花色素以及光受体在马铃薯块茎发育途径中的调控作用，整合各信号通路中分子相互作用和影响，探寻其相关联系，从而构建出分子调控网络。深入研究马铃薯块茎发育途径中的光信号调控机制，可以更好地理解马铃薯块茎的形成发育规律，为马铃薯产量和品质的提高提供理论支撑。

Abstract

Light is an essential factor in the plant growth and development, and various light receptors mediate light involvement in a variety of plant physiological activities. The formation of potato tubers is closely associated with light exposure, and how light receptors influence potato tuber formation at the molecular level remains a research focus in tuber development research. Using existing tuber development mechanisms as a theoretical basis, the regulatory roles of phytochromes and cryptochrome, and photoreceptors in the potato tuber development pathway were summarized, molecular interactions and influences in both signaling pathways were integrated, and the connections between them were explored to propose a molecular regulatory network. Through in-depth analysis of the light signal regulation mechanism in the potato tuber development pathway, enhanced understanding of the formation and development patterns in potato tubers could be achieved, providing scientific basis for enhancing potato yield and quality.
