Transcriptome Sequencing and Biochemical Analysis of Perianths and Coronas Reveal Flower Color Formation in Narcissus pseudonarcissus.

ABSTRACT: Narcissus pseudonarcissus is an important bulbous plant with white or yellow perianths and light yellow to orange-red coronas, but little is known regarding the biochemical and molecular basis related to flower color polymorphisms. To investigate the mechanism of color formation, RNA-Seq of flower of two widely cultured cultivars ('Slim Whitman' and 'Pinza') with different flower color was performed. A total of 84,463 unigenes were generated from the perianths and coronas. By parallel metabolomic and transcriptomic analyses, we provide an overview of carotenoid biosynthesis, degradation, and accumulation in N. pseudonarcissus. The results showed that the content of carotenoids in the corona was higher than that in the perianth in both cultivars. Accordingly, phytoene synthase (PSY) transcr
