title: [The regulation activity of Chlorella virus gene 5' upstream sequence in Escherichia coli and eucaryotic alage].
abstract: The 5' upstream regions of adenine methyltransgerase gene and major coat protein gene (PAMT, PVP54) in Chlorella virus genomes were used to contract transformation vectors in E. coli and eukaryotic algae. The regulation activities of PAMT and PVP54 comparing with PRPL and CaMV35S promoters were analyzed in different E. coli strains and Chlorella species. It is found that the luciferase activity controlled by PAMT is 50-400 times higher than that controlled by PRPL. The regulation activity of PAMT in 2 Chlorella species is obviously higher than that of CaMV35S promoter. It is the first report that the 5' upstream region of Chlorella virus gene has strong regulation activity in eucaryotic algae. The result suggests this regulation sequence will have an excellent application in the eucaryotic algae genetic engineering.
