    植物氮磷营养的长距离信号转导

    Long-distance signal transduction of nitrogen and phosphorus in plants

    • 摘要: 植物应对土壤多变的营养环境需整合和协调地上部和根系的养分感知信息,通过精细而复杂的信号转导机制,调控植物养分应答和生长发育进程。长距离信号转导机制的实现需经由维管系统进行信号分子的长距离运输(故称长距离信号)。在众多矿质营养元素中,氮和磷是限制植物生产力的主要元素。研究表明,蛋白质、小肽和microRNAs等多种分子均可作为长距离信号分子参与调控系统性氮磷信号转导。本文总结了目前鉴定到的氮磷营养长距离信号分子及相关信号转导机制,概述了光对氮磷长距离信号转导的影响,并对长距离信号未来研究方向进行了展望。

       

      Abstract: In response to varied nutrient availability in soil, plants exhibit high physiological and developmental plasticity to integrate and coordinate the information of nutrient sensing between shoots and roots, and systematically regulate the whole-plant nutrient response and growth and development. This signal transduction process largely relies on the transportation of signal molecules via vascular systems, so-called long-distance signaling. Although plants require numerous mineral elements from the soil, the major nutrients that limit plant productivity are nitrogen (N) and phosphorus (P). Recent studies have elucidated that various mobile signals, such as small proteins, peptides, and microRNAs, are responsible for long-distance signaling of N and P. Here, we summarize the long-distance signal molecules identified in N and P nutrition and their related signal transduction mechanisms, provide an overview of the influence of light signals on the long-distance signal of N and P, and also discuss the future research direction of long-distance signals.
