Abstract

Sweet potato flowers were collected for a transcriptome analysis to identify the putative floral-specific and flowering regulatory-related genes by using the RNA-sequencing technique. Pair-end short reads were de novo assembled by an integrated strategy, and then the floral transcriptome was carefully compared with several published vegetative transcriptomes. A total of 2595 putative floral-specific and 2928 putative vegetative-specific transcripts were detected. We also identified a large number of transcripts similar to the key genes in the flowering regulation network of Arabidopsis thaliana.
