Selecting and Establishing the Means of Gene Transfer for Cyanobacteria

Cyanobacteria are prokaryote and oxygenic photosynthetic bacteria that have been used increasingly to study diverse biological processes,and many genetic tools have been developed for cyanobacteria.Considering its unique characteristics,cyanobacteria have been became the ideal host of gene engineering.However,selecting and establishing the means of gene transfer has affected the developments of gene engineering for cyanobacteria.Methods of gene transfer are introduced in regard to characteristic,factors,advantages and disadvantages.The best means of gene transfer for various cyanobacteria is summed up.Many available ways of gene transfer enhance the opportunities for possible biotechnological applications of cyanobacteria.All of these will quicken development of gene engineering of cyanobacteria.;
