植物根部热形态建成的研究进展

Recent Advances on Plant Root Thermomorphogenesis

摘要

植物发育具有高度可塑性。当环境温度升高时，植物的茎和叶柄会伸长，从而促进植物叶片表面降温，这一过程被称为热形态建成。高温也会引起植物根的伸长，有学者称之为根部热形态建成。目前关于植物地上部分的热形态建成调控已有较多研究，植物根部热形态建成的调控机制研究和相关综述论文尚不多。本文综述了近年来在植物根部热形态建成领域的相关研究进展，并对今后的研究方向进行了展望。

Abstract

Plant development is highly plastic. As ambient temperature increased， plant stems and petioles elongated， and promoted leaf surface cooling， the process known as thermomorphogenesis. High temperatures also triggered root elongation， which named as root thermomorphogenesis. There were many studies on the regulation of plant shoot thermomorphogenesis， but few investigations on the regulatory mechanisms of plant root thermomorphogenesis. In this review， we summarized the recent progresses in the field of plant root thermomorphogenesis， and proposed future research directions.
