Web[10,11]. Two homologous bHLH proteins, GLABRA3 (GL3) and ENHANCER OF GLABRA3 (EGL3) enhance anthocyanin biosynthesis together with PAP1 and PAP2 [7]. In contrast, CAPRICE (CPC), one of R3-type MYB genes, compete with the binding of PAP1/2 to GL3/EGL3 and disrupt the TTG1-GL3/ EGL3-PAP1/2 protein complex, thus inhibiting the … WebWe show that two Arabidopsis genes encoding bHLH proteins, GLABRA3 (GL3) and ENHANCER OF GLABRA3 (EGL3), act in a partially redundant manner to specify root epidermal cell fates. Plants homozygous for mutations in both genes fail to specify the non-hair cell type, whereas plants overexpressing either gene produce ectopic non-hair cells. ...
WebJun 19, 2024 · The basic helix-loop-helix (bHLH) proteins GL3 (GlABRA 3) and EGL3 (Enhancer of GLABRA 3) are transcription factors that establish physical interactions with GL1 and TTG1 to regulate trichome development in Arabidopsis. In this study, we identified GL3 and EGL3 homologous genes from Rosa roxburghii, named RrGL3 and RrEGL3, … WebThe bHLH genes GLABRA3 (GL3) and ENHANCER OF GLABRA3 (EGL3) specify epidermal cell fate in the Arabidopsis root The position-dependent specification of the hair and non-hair cell types in the Arabidopsis root epidermis provides a simple model for the …
