Dendrobium nobile flower Transcriptome

Dendrobium nobile L. is a rare orchid plant with high medicinal and ornamental value, and extremely few genetic species resources are remaining in nature. In the normal purple flower population, a type of population material with a white flower variation phenotype has been discovered, and through pigment component determination, flavonoids were preliminarily found to be the main reason for the variation. Hence, this study mainly explored the different genes and metabolites at different flowering stages and analysed the flower colour variation mechanism through transcriptome- and flavonoid-targeted metabolomics.
