Abstract

Root hairs play important roles for the acquisition of nutrients, microbe interaction and plant anchorage. In addition, root hairs provide an excellent model system to study cell patterning, differentiation and growth. Arabidopsis root hairs have been thoroughly studied to understand how plants regulate cell fate and growth in response to environmental signals. Accumulating evidence suggests that a multi-layered gene regulatory network is the molecular secret to enable the flexible and adequate response to multiple signals. In this review, we describe the key transcriptional regulators controlling cell fate and/or cell growth of root hairs. We also discuss how plants integrate phytohormonal and environmental signals, such as auxin, ethylene and phosphate availability, and modulate the level of these transcriptional regulators to tune root hair development.

摘要

根毛在养分获取、微生物相互作用和植物固着方面发挥着重要作用。此外，根毛为研究细胞模式、分化和生长提供了一个出色的模型系统。拟南芥根毛已得到充分研究，以了解植物如何响应环境信号来调节细胞命运和生长。越来越多的证据表明，一个多层基因调控网络是使植物能够对多种信号做出灵活且充分响应的分子奥秘。在本综述中，我们描述了控制根毛细胞命运和/或细胞生长的关键转录调节因子。我们还讨论了植物如何整合植物激素和环境信号，如生长素、乙烯和磷的有效性，并调节这些转录调节因子的水平以调控根毛发育。
