Abstract

Plant developmental processes are very flexible and highly depend on environmental factors. This is largely due to the existence of regulatory mechanisms that systemically control development on the whole plant level. In plants, regulatory peptides produced in the roots have been identified that are activated in response to different factors influencing root system, such as variation in the level of macronutrients (first of all, nitrogen and phosphorus) in the soil, influence of symbiotic microorganisms (soil rhizobial bacteria and arbuscular mycorrhiza fungi), and water deficiency. Among the systemically acting peptides, the most thoroughly investigated are CLE (CLAVATA3/EMBRYO SURROUNDING REGION-related) and CEP (C-TERMINALLY ENCODED PEPTIDES) peptides that are capable of travelling through the xylem from the roots to the shoot and triggering responses via binding to specific receptors operating in the phloem of the leaf. This review focuses on the role of these two groups of peptides in molecular dialog between the root and shoot.

调控肽在根与芽之间的分子对话及其在植物发育的系统控制中的作用

摘要

植物发育过程非常灵活，并且高度依赖环境因素。这很大程度上是由于存在系统地控制整个工厂级别的开发的监管机制。在植物中，已经确定了根中产生的调节肽，这些肽可以响应影响根系统的不同因素而被激活，例如土壤中大量营养素（首先是氮和磷）水平的变化，共生微生物的影响（土壤的根瘤菌和丛枝菌根真菌）和水分缺乏。在具有全身作用的肽中，研究最彻底的是CLE（与CLAVATA3 / EMBRYO周围环境相关的肽）和CEP（C-末端编码肽）肽，它们能够从根部穿过木质部到达枝条，并通过与特定的受体结合而触发响应。叶子的韧皮部。这篇综述集中在这两类肽在根与芽之间的分子对话中的作用。
