摘要 | The sequencing of BAC clones (similar to 100 kb) can reveal some characteristics of a genome that are challenging to obtain based on short sequences. Additionally, although the immune genes of the Zhikong scallop (Chlamys farreri) have been studied widely, few analyses have been conducted at the DNA level. In this study, four C. farreri BAC clones containing innate immune genes, including hsp70, Igbp (lipopolysaccharide and beta-1,3-glucan binding protein), serine protease and a gene with an immunoglobulin-like domain, were sequenced and analyzed both to explore the genomic characteristics of C. farreri based on long DNA sequences and to promote the study of C. farreri immune genes at the DNA level. The total length of the four BACs was 389.98 kb. A total of 34 genes were predicted in these sequences, and several features of protein-coding regions in the C. farreri genome were inferred based on this information. Two LGBP genes Were located close together in a 22-kb region in one BAC clone, indicating the physical linkage of some immune genes in C. farreri. A cluster of membrane transport genes was also observed; these genes might play important roles in eliminating toxins in C. farreri, which lives as a filter feeder. Further analysis showed 15.43% of the BAC sequence was repetitive. Tandem repeats were the most abundant repeat type, followed by transposable elements. A total of 31 SSRs were predicted in the four BACs. An IS10 family transposon was identified, and a suspected regulatory non-coding RNA gene for this transposon (RNA-OUT) was observed to overlap with it complementarily. This work will promote future studies on the genomics, immune system and non-coding regions of C. farreri. (C) 2012 Elsevier B.V. All rights reserved. |
