Flavonoid remodeling and functional characterization of CrHPPD during salt stress response in Carex rigescens.
Genotype- and tissue-specific flavonoid remodeling in C. rigescens under salt stress and overexpression of CrHPPD in Arabidopsis thaliana are revealed, suggesting two stress-responsive components of phenylalanine/tyrosine-derived metabolism, although their direct mechanistic connection requires further validation.
