| 英文摘要 | As a benthic filter-feeder of estuaries, the eastern oyster, Crassostrea virginica, faces tremendous exposure to microbial pathogens. How eastern oysters without adaptive immunity survive in pathogen-rich environments is of fundamental interest, but studies on its immune system are hindered by the lack of genomic resources. We sequenced the transcriptome of an adult oyster with short Illumina reads and assembled 66,229 contigs with a N50 length of 1,503 bp. The assembly covered 89.4 % of published ESTs and 97.9 % of mitochondrial genes demonstrating its quality. A set of 39,978 contigs and unigenes (> 300 bp) were identified and annotated by searching public databases. Analysis of the gene set yielded a diverse set of 657 genes related to innate immunity, including many pertaining to pattern recognition, effectors, signal transduction, cytokines, and apoptosis. Gene families encoding C1q domain containing proteins, CTLD, IAPs, Ig_I-set, and TRAFs expanded in C. virginica and Crassostrea gigas. Many key genes of the apoptosis system including IAP, BAX, BAC-2, caspase, FADD, and TNFR were identified, suggesting C. virginica posses advanced apoptosis and apoptosis-regulating systems. Our results show that short Illumina reads can produce transcriptomes of highly polymorphic genomes with coverage and integrity comparable to that from longer 454 reads. The expansion and high diversity in gene families related to innate immunity, point to a complex defense system in the lophotrochozoan C. virginica, probably in adaptation to a pathogen-rich environment. |
