De novo transcriptomes of floral bracts for 22 Bougainvillea accessions. Bougainvillea glabra

Bougainvillea glabra is an ornamental tree or shrub with nearly 200 years of application in gardening and landscapes globally. Recently, the growing research interest in the applications of B. glabra extracts, such as medicinal applications, and synthetic materials for nutraceuticals, has led to the development of new techniques to be utilized for studying B. glabra. Moreover, the formations of polymorphic coloration and the mechanism of metamorphic bracts in B. glabra cultivars are worthy of study. However, the genomic information for B. glabra is lacking completely which hinders the progress of gene-level research and genetic applications. We sequenced the bracts transcriptomes of 22 B. glabra accessions and generated 80.32 Gb clean data. After de novo assembly and optimization, 176,052 unigenes with E90N50 of 2,468bp and annotation data to six databases were obtained. In addition, a total of 117,246 CDSs were detected, and 36,739 SNPs were annotated in 68,509 unigenes. These transcriptome data are valuable for gene mining and expression profiling experiments or other scientific areas.
