TL;DR
A FaDOF2-FaMYB4 cascade module that regulates anthocyanin biosynthesis in the octoploid cultivated strawberry is revealed, thereby extending the known regulatory network of fruit pigmentation and providing potential molecular targets for breeding improved color traits.
It is hypothesized that high temperature suppresses anthocyanin accumulation through a dual mechanism of transcriptional inhibition and hormonal modulation, while simultaneously promoting pigment stabilization via glycosylation.
To reveal the relationship of anthocyanin biosynthesis in Actinidia arguta, we cloned a typical R2R3-MYB transcription factor-AaMYB17 gene from the cultivar "Dahongpao." Expression analysis showed that AaMYB17 was significantly negatively correlated with anthocyanin accumulation and the expression of most of the struct...
Yeast one-hybrid and dual-luciferase assay demonstrated that CabHLH118 can bind to the upstream promoter of CaF3'H and promote anthocyanin formation, and CabHLH118 may respond to blue light to enhance anthocyanin biosynthesis, although the underlying mechanism requires further verification.
Plant leaves often develop red coloration in response to aging and environmental changes. High light or continuous light treatments can elevate anthocyanins, which we observed in normally green kiwifruit leaves. The underlying mechanism in this response was investigated using transcriptomic analysis. Resul...
A novel mechanism by which FaERF4 specifically regulates PA biosynthesis and provides a theoretical basis for metabolic engineering of functional nutrients in strawberry is revealed.
MYB transcription factors are key regulators of anthocyanin biosynthesis, acting as both activators and repressors. However, the functional characterization of R2R3-MYB repressors in litchi (Litchi chinensis) remains limited. In this study, we identified and characterized LcMYBC2-L1 as an R2R3-MYB transcriptional repre...
