| Outline of Final Research Achievements |
We found that chub mackerel (Scomber japonicas) shows higher mortality in the high water temperature periods comparison with closely related species, blue mackerel (S. australasicus). In the present study, we performed that transcriptome analysis to understand such a disease resistance traits showing in blue mackerel with NGS technology. As the results of RNA-seq and subsequent de novo assembly, 1,072 contigs for chub mackerel and 52,530 contigs for blue mackerel. We further conducted reciprocal best match to estimate orthologs between two species and 13,875 contigs were obtained. Using this orthologs list of two Scomber species, we found expression levels of several immune related genes were siginificantly different. Theses genes are mostly related to acute immune reaction and inflammation.
