Red pap1-D cells of Arabidopsis thaliana have been cloned from production of anthocyanin pigmentation 1-Dominant (pap1-D) plants. The red cells are metabolically programmed to produce high levels of anthocyanins by a WD40-bHLH-MYB complex that is composed of the TTG1, TT8/GL3 and PAP1 transcription factors. Here, we report that indole 3-acetic acid (IAA), naphthaleneacetic acid (NAA) and 2,4-dichlorophenoxyacetic...
Nitrogen nutrients can regulate anthocyanin biosynthesis in Arabidopsis thaliana. In this investigation, we report the nitrogen regulation of anthocyanin biosynthesis activated by TTG1–GL3/TT8–PAP1 in red pap1-D cells. To understand the mechanisms of nitrogen regulation, we employed red pap1-D cells and wild-type cells (as a control) to examine the effects of different nitrogen treatments on anthocyanin...
We report metabolic engineering of Arabidopsis red cells and genome-wide gene expression analysis associated with anthocyanin biosynthesis and other metabolic pathways between red cells and wild-type (WT) cells. Red cells of A. thaliana were engineered for the first time from the leaves of production of anthocyanin pigment 1-Dominant (pap1-D). These red cells produced seven anthocyanin molecules including...
The number of different anthocyanin molecules potentially produced by Arabidopsis thaliana and which anthocyanin molecule is the first product of anthocyanidin modification remain unknown. To accelerate the understanding of these questions, we investigated anthocyanin biosynthesis in rosette leaves of both pap1-D and wild-type (WT) A. thaliana plants grown in nine growth conditions, which were composed...
The Arabidopsis PAP1 gene (At1g56650) encodes the MYB75 transcription factor, which has been demonstrated to essentially regulate the biosynthesis of anthocyanins. Our previous study showed that ectopic expression of the PAP1 gene led to high pigmentation of anthocyanins in all tissues of transgenic tobacco plants. In order to understand the mechanisms of how PAP1 regulates anthocyanin biosynthesis...
