Abstract:

As a worldwide economic fish,tilapia contains rich nutrition and is one of the most important fish cultured in freshwater. Prokaryotic expression is a technology that combines foreign genes with the expression vectors by gene cloning technology and transfers the combined genes into expression strains in purpose of translating the goal gene into protein. Specific genes can be translated into protein by this technology,and thus provide basic materials for protein level research of specific genes. With the expansion of tilapia industry,researches on tilapia are increasing deeply,especially the genes related to immunity and growth. Prokaryotic expression has made great contribution to the study of these genes in protein level. However,prokaryotic expression needs the match of a suitable expression vector and host,and inappropriate expression vectors and hosts results in the failure of expression. This paper reviews the studied genes of tilapia by prokaryotic expression,summarizes the genes types,vectors and hosts for prokaryotic expression,as well as the uses and limitations of expressed protein,aiming to offer references for further researches of tilapia genes in protein level.
