Abstract

Root hair growth dramatically expands the root surface area, thus facilitating water and nutrient uptake. Until recently, the molecular mechanism underlying root hair growth was unknown. Recent studies have revealed that the transcription factor ROOT HAIR DEFECTIVE 6 LIKE 4 (RSL4) coordinates hormonal, environmental, and developmental factors to trigger polar growth.

摘要

根毛的生长显著扩大了根的表面积，从而促进了水和养分的吸收。直到最近，根毛生长的分子机制还不清楚。最近的研究表明，转录因子根毛缺陷 6 样 4（RSL4）协调激素、环境和发育因素来触发极性生长。
