摘　　要：海藻糖-6-磷酸代谢通路是植物响应非生物胁迫生理调控网络中的重要组成部分,海藻糖-6-磷酸合成酶基因TPS(Trehalose-6-phosphate synthase)是植物合成海藻糖的关键基因。为了更加充分地理解TPS基因在植物应答非生物胁迫、调节开花时间等方面的作用,本文首先对植物TPS基因家族成员的系统进化关系及序列结构信息进行了研究,重点论述了TPS基因在植物响应干旱、盐害、高温、低温胁迫中的调控功能及分子作用机制,最后对TPS基因参与植物开花调控的研究进展进行了综述。本文深入总结了目前植物TPS基因响应非生物胁迫及开花调控的研究进展,并对今后TPS同源基因的研究方向和应用价值进行了展望。The trehalose-6-phosphate metabolic pathway is an important component of the plant physiological regulation network in response to abiotic stress.Trehalose-6-phosphate synthase(TPS)is a key gene for trehalose synthesis in plants.To better understand the role of the TPS gene in plant response to abiotic stress and regulation of flowering time,this study presents an overview of current information on the phylogenetics and sequence structure of plant TPS gene family members,as well as the regulatory function and molecular mechanism of TPS in plant responses to drought,salt damage,high temperature,and low temperature stress,and research progress regarding its effects on plant flowering regulation.This study presents a comprehensive summary of research progress on the TPS gene in response to abiotic stress and flowering regulation,while also providing future research directions and potential applications of TPS homologs.
