title: Genome-wide identification of GLABRA3 downstream genes for anthocyanin biosynthesis and trichome formation in Arabidopsis.
abstract: 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.
