Summary Flavonoids are important plant pigments and defense compounds; understanding the transcriptional regulation of flavonoid biosynthesis may enable engineering crops with improved nutrition stress tolerance. Here, we characterize R2R3‐MYB domain subgroup 7 transcription factor CaMYB39, which regulates flavonol primarily in chickpea trichomes. CaMYB39 overexpression was accompanied by a change flux availability for phenylpropanoid pathway, particularly biosynthesis. Lines overexpressing...
Proanthocyanidins are oligomeric flavonoids that promote plant disease resistance and benefit human health. Banana is one of the world's most extensively farmed crops its fruit pulp contain proanthocyanidins. However, transcriptional regulatory network fine tunes proanthocyanidin biosynthesis in banana remains poorly understood. We characterised two proanthocyanidin-specific R2R3 MYB activators (MaMYBPA1-MaMYBPA2) four repressors (MaMYBPR1-MaMYBPR4) to elucidate mechanisms underlying...
Plant flavonols act primarily as ultraviolet radiation absorbers, reactive oxygen species scavengers, and phytoalexins, they contribute to biotic abiotic stress tolerance in plants. Banana (Musa acuminata), an herbaceous monocot important fruit crop, accumulates flavonol derivatives different organs, including the edible pulp. Although content varies greatly molecular mechanisms involving transcriptional regulation of synthesis banana are not known. Here, we characterized three SG7-R2R3 MYB...
Abstract Flavonols are structurally and functionally diverse biomolecules involved in plant biotic abiotic stress tolerance, pollen development, inhibition of auxin transport. However, their effects on global gene expression signaling pathways unclear. To explore the roles flavonol metabolites signaling, we performed comparative transcriptome targeted metabolite profiling seedlings from flavonol-deficient Arabidopsis loss-of-function mutant synthase1 (fls1) with without exogenous...

We characterized two proanthocyanidin-specific R2R3 MYB activators (MaMYBPA1-MaMYBPA2) four repressors (MaMYBPR1–MaMYBPR4) to elucidate mechanisms underlying regulation of banana.

Abstract Flavonols are structurally and functionally diverse molecules playing roles in plant biotic abiotic stress tolerance, auxin transport inhibition, pollen development, etc. Despite their ubiquitous occurrence land plants multifunctionality, the effect of perturbation flavonol biosynthesis over global gene expression pathways other than flavonoid has not been studied detail. To understand signaling role different metabolites, herein, we used deficient Arabidopsis thaliana...
