主  题:Dunaliella salina Ds MAPK Antisense expression vector Semi-quantitative RT-PCR 

摘      要:In order to investigate the role of MAPK gene in adaptation of Dunaliella salina to hypersaline environment, the Ds MAPK gene of D. salina was amplified by PCR. After inverted insertion of the open reading flame ofDs MAPK gene into downstream sequence of 35S promoter of plant expression vector, an antisense expression vector of Ds MAPK gene was successfully constructed and introduced into D. salina cells by LiAc/PEG-mediated method. The expression of Ds MAPK gene in transgenic D. salina was analyzed by semi-quantitative RT-PCR method. The results showed that the expression of Ds MAPK gene in D. salina was significantly inhibited at the transcriptional level. The study laid the foundation for further identification of the function of Ds MAPK gene.
