Abstract:
... Pigmented rice, particularly black rice, has attracted widespread global interest due to its high nutritional value. To obtain a better understanding of differential metabolites between pigmented rice and white rice, we used a widely-targeted metabolomics-based approach to investigate the metabolite profiling of black, red, glutinous, and common white rice. In total, 732 metabolites were identifie ...

Abstract:
... Meconopsis (Meconopsis spp.) belongs to the family Papaveraceae and is the representative alpine flora in the Pan Himalaya region. Diversity in color is a key taxonomic feature of Meconopsis species, which makes it to be an ideal material for mechanism analysis of petals coloration; however, few studies have focused on this topic. In this study, we selected three Meconopsis species with different ...

Abstract:
... Flavonoids are one of the main pigments in horticultural fruit. The AP2/ERF transcription factors play various roles in higher plants, and thus, MdAP2–34 has been reported to regulate carotenoid accumulation in apple. However, it is unclear whether light interferes with the flavonoid accumulation in apple fruit flesh. Here, we found that apple of ‘Benin Shogun’ fruit flesh had higher levels of fla ...
