Abstract:

In order to explore the molecular genetic mechanism of fur color formation between chinchilla rex rabbits and white rex rabbits.The experiments were divided into 3 groups,every group contained one chinchilla rex rabbit and one white rex rabbit,which came from full-sib family.The Agilent’s rabbit gene expression microarray was used to determine the differentially expression genes between different fur color groups of rex rabbits,and the expression patterns of selected differentially expressed genes were further identified by quantitative real-time PCR.The results showed that 545,1 680 and 2 092 differentially expressed genes associated with fur color of rex rabbits were screened out from 3 groups of chinchilla rex rabbits and white rex rabbits,respectively.A total of 172 mutual genes were found among these 3 rex rabbits groups.GO (Gene Ontology) analysis results revealed that the differentially expressed genes were related to cell differentiation,proliferation,apoptosis,growth,ionic transport altered and immune response,etc.The quantitative real-time PCR showed gene expression trend of Creb1,Wnt2,Gnaq and Gna14 genes was consistent with that of gene expression microarray data,indicating that the result of gene chip was reliable.Combined with bioinformatic analysis and related literatures,some genes were potentially related to fur color formation,such as Creb1,THWnt2,GnaqDvl1,Mapk12,and so on.
