Abstract
Cherry shrimp (Neocaridina denticulata sinensis) is one of the main ornamental shrimp because of its bright body color. β, β-carotene 9′,10′-dioxygenase (BCO2) is closely related to the body color produced by carotenoids. In order to study the role of NdBCO-like4 (homologous gene of BCO2) in the pigmentation of cherry shrimp, the expression profiles, RNA interference, and SNP genotyping were applied in this study. The NdBCO-like4 expression varied significantly among four color strains and five development stages (p A. The synonymous SNP exhibited significantly different genotype frequencies between the yellow and wild strains compared to other strains (p
