Journal Article
BrGSTF12, an anthocyanin-related glutathione S-transferase gene, is essential for light-induced anthocyanin accumulation in zicaitai (Brassica Rapa Var. purpuraria)
2025
Overview
Background
Anthocyanins are a group of polyphenolic pigments that play essential biological roles and significantly influence the quality of agricultural produce. Bioinformatics approaches were employed to predict and identify potential genes involved in the sequestration of anthocyanins in Zicaitai (
Brassica rapa
var.
purpuraria
) utilizing data from the transcriptome database.
Results
In this study 0-hour light (dark) and 8-hour light treatments of Zicaitai were examined using transcriptome analysis. RNA-seq analysis indicates that 24 important anthocyanin biosynthesis genes, including 5

4CL
, 3

, 2
F3H
, 1

, 2
ANS
, and 5
UGFT
were significantly differentially expressed between 0-hour and 8-hour light treatment. The transcript levels of the glutathione S-transferase gene,
BrGSTF12
, were significantly higher at 8 h compared to 0 h.
BrGSTF12
expression level correlated with the patterns of anthocyanins content in each tissue of Zicaitai. Functional complementation in the
Arabidopsis tt19
mutant further demonstrated that
BrGSTF12
was involved in the transport of anthocyanins. Additionally, expression analysis showed that
BrMYB114
levels were significantly elevated at 8 h, and dual-luciferase assays confirmed that
BrMYB114
effectively trans-activated the promoter of the
BrGSTF12
gene.
Conclusion
This study provides molecular evidence supporting the regulatory roles of
BrGSTF12
and
BrMYB114
in enhancing anthocyanin accumulation in Zicaitai under light induction. The findings contribute to a deeper understanding of the mechanisms behind anthocyanin biosynthesis and transport, offering valuable insights that could aid in breeding anthocyanin-rich crops, and paving the way for new opportunities in crop development.
