摘　　要：根毛的生长发育有助于植物获取土壤水分和矿质营养元素。对根毛的深入研究不仅对了解植物根系的适应性、吸收能力和生长调控机制具有理论和实践意义,而且为细胞分化决定、发育和程序化死亡机制探索提供了理论基础。本文围绕小G蛋白Rop参与的根毛起始和尖端生长,转录因子参与的根毛细胞命运决定、根毛起始和根毛发育,Ca^(2+)参与的根毛尖端生长,磷酸盐参与的根毛尖端生长及生长素参与的根毛生长等方面,归纳综述了包括根毛细胞命运决定、根毛起始及根毛尖端生长在内的根毛生长发育过程及分子调控机制,并简单总结出调控根毛生长发育基因的分子调控网络。对植物根毛对养分的吸收、获取及利用、影响植物根毛生长发育的分子调控机制进行阐述,为根毛生长发育的分子调控机制研究提供理论参考。The growth and development of root hairs contribute to the acquisition of soil moisture and mineral nutrients by plants.The comprehensive investigation of root hairs holds great theoretical and practical importance in comprehending the adaptability,absorption capacity,and growth regulation mechanism of plant roots.Additionally,it establishes a solid foundation for further exploration into the mechanisms of cell differentiation,cell development,and programmed cell death.This paper delved into various aspects of root hair growth and development,including the involvement of small G protein Rop in root hair initiation and tip growth,transcription factors involved in cell fate determination,root hair initiation and development,root hair tip growth involved in Ca^(2+),root hair tip growth involved in phosphate and root hair growth involved in auxin.A comprehensive overview of the molecular regulation mechanisms governing root hair growth and development,including root hair cell fate determination,initiation,and tip growth was provided,along with a brief summary of the molecular regulation network of genes regulating root hair growth and development.The primary objective of this review was to provide theoretical references for the molecular regulation mechanism of root hair growth and development and to enhance our understanding of the absorption,acquisition,and utilization of nutrients by plant root hair.
