Abstract Background Bracts are important for ornamental plants, and their developmental regulation process is complex; however, relatively little research has been conducted on bracts. In this study, physiological, biochemical morphological changes in Bougainvillea glabra leaves, leaf buds bracts during seven periods were systematically investigated. Moreover, transcriptomic data of B. obtained using PacBio Illumina sequencing technologies, key genes regulating development screened. Results Scanning electron microscopy revealed that the develop via a involving regression hairs color change from green to white. Transcriptome 79,130,973 bp transcript sequences 45,788 transcripts.

Abstract The naturally occurring bisexual cone of gymnosperms has long been considered a possible intermediate stage in the origin flowers, but mechanisms governing formation remain largely elusive. Here, we employed transcriptomic and DNA methylomic analyses, together with hormone measurement, to investigate molecular underlying development conifer Picea crassifolia . Our study reveals “bisexual” expression profile cones, especially patterns B-class, C-class LEAFY genes, supporting out male model. GGM7 could be essential for initiating cones. methylation reconfiguration cones affects key genes development, including PcDAL12 , PcDAL10 PcNEEDLY PcHDG5 Auxin likely plays an important role female structures This unveils potential responsible conifers may shed light on evolution bisexuality.
