miR-330 Targeting BCO2 Is Involved in Carotenoid Metabolism to Regulate Skin Pigmentation in Rainbow Trout (Oncorhynchus mykiss)

the full-length cDNA sequence of β-carotene oxygenase 2 (BOC2) from the rainbow trout was obtained using rapid-amplification of cDNA ends technology, and qRT-PCR was used to investigate the differential expression of miR-330 and BCO2 in 14 developmental stages and 13 tissues between wild-type rainbow trout and yellow mutant rainbow trout.
