As sessile organisms, plants must be highly adaptable to the changing environment by modifying their growth and development. Plants rely on their underground part, the root system, to absorb water and nutrients and to anchor to the ground. The root is a highly dynamic organ of indeterminate growth with new tissues produced by root stem cells. Plants have evolved unique molecular mechanisms to fine-tune root developmental processes, during which phytohormones play vital roles. These hormones often relay environmental signals to auxin signaling that ultimately directs root development programs. Therefore, the crosstalk among hormones is critical in the root development. In this review, we will focus on the recent progresses that jasmonic acid (JA) and ethylene signaling are integrated into auxin in regulating root development of and discuss the key roles of transcription factors (TFs) ethylene response factors (ERFs) and homeobox proteins in the crosstalk.
作为固着生物,植物必须通过改变其生长发育来高度适应不断变化的环境。植物依靠其地下部分即根系来吸收水分和养分并固定于地面。根是一个具有不定生长特性的高度动态的器官,由根干细胞产生新的组织。植物进化出了独特的分子机制来微调根的发育过程,在此过程中植物激素发挥着至关重要的作用。这些激素常常将环境信号传递给生长素信号传导途径,最终指导根的发育程序。因此,激素之间的相互作用在根的发育中至关重要。在本综述中,我们将重点关注茉莉酸(JA)和乙烯信号传导整合到生长素中以调节根发育的最新进展,并讨论转录因子(TFs)乙烯响应因子(ERFs)和同源框蛋白在这种相互作用中的关键作用。
