根毛在营养物质的获取、微生物的相互作用和植物的固定等方面起着重要的作用。此外，根毛为研究细胞构型、分化和生长提供了一个很好的模型系统。拟南芥根毛已经被深入研究，以了解植物如何调节细胞命运和生长以响应环境信号。越来越多的证据表明，一个多层次的基因调控网络是使人们能够灵活和充分地响应多种信号的分子秘密。在这篇综述中，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控因子。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、乙烯和磷酸盐的有效性，并调节这些转录调节因子的水平，以调节根毛的发育。
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.
