Cloning and expression of the σC gene of avian reovirus

7% at amino acid level:the identities of σB and σC genes,which can induce to produce group-specific and type-specific neutralization antibodies,were only 52.

The construction of DNA vaccine of Avian reovirusσC gene delivered by attenuated Salmonella Typhimurium and identificationA pair of primers were designed and synthesized according to the previously publiched sequence of proteinσC gene of Avian reovirus(ARV)and used to amplifyσC gene by polymerase chain reaction.

Biosynthesis of coenzyme Q in the micro organism and the corresponding enzymes catalyzing eachreaction are reviewed, as well as their coding genes.

Objective To identify the coding gene of 53×10 3 protein of bacteriophage PaP3.

This paper briefly introduces the research findings covering in discovery,origin,distribution,biochemical characteristics,coding gene,and expression of myrosinase.

Cloning and sequence analysis of human urease B encoding gene of Helicobacter pylori;

PCR-RFLP and PCR techniques were used to analyse the encoding genes of the active factors from Bacillus thuringiensis new isolate strain WB9.

CellobiohydrolaseⅡ(CBHⅡ) encoding gene cbh2 was obtained from Trichoderma viride by using the reverse transcription polymerase chain reaction(RT-PCR) method,and was then cloned into the integrative expression vector pScIKP of Saccharomyces cerevisiae to generate a recombinant plasmid pScIKP-cbh2.
