Background: has long been used in Northeast Asia as a food and folk medicine to treat various diseases. The intense blue color of corolla is its characteristic feature.
Objectives: By comparing deep transcriptomic data of and its white cultivar, we intended to elucidate the molecular mechanisms concerning the biosynthesis of anthocyanins in this plant.
Material And Methods: We sampled blue mature flowers (PgB) and yellow young buds (PgY) of . Meanwhile, mature flowers (PgW) of white cultivar were also collected for RNA extraction and next-generation sequencing. After high-throughput sequencing, Trinity software was applied for de novo assembly and the resultant 49934 unigenes were subjected for expression analysis and annotation against NR, KEGG, UniProt, and Pfam databases.
Results: In all, 32.77 Gb raw data were generated and the gene expression profile for the flowers of was constructed. Pathway enrichment analysis demonstrated that genes involved in flavone and flavonol biosynthesis were differently expressed.
Conclusions: The extremely low expression of flavonoid-3',5'-hydroxylase in PgY and PgW was regarded as the reason for the formation of its white cultivar. Our findings provided useful information for further studies into the biosynthetic mechanism of anthocyanins.

Phytohemagglutinin (PHA), a natural tetramer comprising PHA-E and PHA-L subunits that preferentially bind to red and white blood cells, respectively, constitutes a significant antinutritional and allergenic factor in common bean seeds. The accurate measurement of PHA content is a prerequisite for ensuring food safety inspections and facilitating genetic improvements in common bean cultivars with reduced PHA levels. Currently, mainstream methods for PHA quantification involve hemagglutination assays and immunodetection, but these methods often require fresh animal blood and lack specificity and accuracy.

The pigmentation of various components leads to different colors of roses. However, the intricate molecular machinery and metabolic pathways underlying rose pigmentation remain largely unexplored. In this study, we determined that pink and black-red petals contain abundant anthocyanins, reaching concentrations of 800 μg/g and 1400 μg/g, respectively, significantly surpassing those in white and yellow petals.
