GLABRA3 （GL3）是一种bHLH转录因子，先前已被证明参与拟南芥花青素的生物合成和毛状体的形成，但其下游的靶基因仍在很大程度上未知。在这里，我们发现GL3广泛存在于拟南芥的营养和生殖器官中。通过RNA测序，在幼芽和膨大真叶中发现了GL3参与花青素生物合成和毛状体形成的新下游靶基因。gl3介导的基因表达在这两个生物过程中具有组织特异性。本研究为进一步了解gl3介导的拟南芥花青素生物合成和毛状体形成的调控网络提供了新的线索。(C) 2017爱思唯尔公司版权所有。
GLABRA3 (GL3), a bHLH transcription factor, has previously proved to be involved in anthocyanin biosynthesis and trichome formation in Arabidopsis, however, its downstream targeted genes are still largely unknown. Here, we found that GL3 was widely present in Arabidopsis vegetative and reproductive organs. New downstream targeted genes of GL3 for anthocyanin biosynthesis and trichome formation were identified in young shoots and expanding true leaves by RNA sequencing. GL3-mediated gene expression was tissue specific in the two biological processes. This study provides new clues to further understand the GL3-mediated regulatory network of anthocyanin biosynthesis and trichome formation in Arabidopsis. (C) 2017 Elsevier Inc. All rights reserved.
