同源重組敲除三角褐指藻基因的研究
[Abstract]:In order to study the gene function of Phaeopsis triangularis by using gene knockout technique, a homologous recombinant gene knockout vector was constructed using glycerine kinase gene as target gene. The vector was successfully transformed into Phaeodactylum triangularis by microelastic bombardment, and 34 positive transgenic alga strains were obtained by Zeocin screening and PCR verification with 100 渭 g / mL Zeocin. Furthermore, the expression and growth of glycerine kinase in the transgenic alga strain were analyzed. The results showed that extracellular glycerol combined with culture did not affect the growth of transgenic alga cells. Glycerol kinase was not expressed or decreased. By constructing knockout vector, genetic transformation was completed, positive transgenic algae were screened, and the characters of transgenic algae were further studied. Finally, a research system of homologous recombinant gene knockout technique was established to study the gene function of Phaeopsis triangularis.
