transcriptome data of stony corals
Coral reefs are import for marine ecological system. Recent years, with increasing global temperatures caused by climate change, coral bleaching is considered as a major threat to coral reefs worldwide. However, there is not enough molecular information of the stony corals and little known about the molecular mechanism on coral bleaching. We sequenced 815 million reads for 14 species of stony corals using Illumina X-TEN platforms. we conducted de novo transcriptome assembly of all the sequenced species. There were 271 to 762 thousand contigs for the 14 species, with N50 ranging from 629 to 1427 bp. There were 66 to 114 thousand unigenes with predicted open reading frames and 74.3% to 80.5% of these unigenes were functionally annotated by searching against NCBI's non-redundant. From the result of annotation, there are 20.2% to 48.9% unigenes with best-hit sequences from corals, and 28.3% to 51.6% from symbiotic algae, except Tubastraea coccinea. With these data we developed a online database ScleractiniaTBase. The features online BLAST, keyword searching for unigenes/functional terms were included. Whole assembled transcriptomes from the sequenced 14 stony corals can also be downloaded. In summary, we provided comprehensive transcriptome data for 14 stony corals from Scleractinia and created a publicly accessible database with a user-friendly interface to facilitate future basic and applied studies on stony corals.
