Abstract
Phosphate (Pi) deficiency is one of the major adverse factors limiting plant growth and production. Enhanced RH development is thought to be the typical root morphological response under Pi deficiency, which will enhance the utilization of Pi resources from soil. Here, we report that MYB30-EIN3 module is functionally implicated in Pi deficiency-induced RH development in Arabidopsis. MYB30 and EIN3 antagonistically regulate RH growth via transcriptional regulation of as well as other PSR genes, resulting in fine-tuned Pi uptake under Pi deficiency.
摘要
磷酸盐（Pi）缺乏是限制植物生长和生产的主要不利因素之一。增强 RH 发育被认为是 Pi 缺乏下典型的根系形态响应，这将增强植物从土壤中利用 Pi 资源的能力。在这里，我们报告 MYB30-EIN3 模块在拟南芥 Pi 缺乏诱导的 RH 发育中具有功能作用。MYB30 和 EIN3 通过转录调控以及其他 PSR 基因拮抗调节 RH 生长，从而在 Pi 缺乏下精细调节 Pi 摄取。
