感染原绿球藻和聚球藻的噬藻体基因组中普遍存在与psbA、psbD和 hli等同源的基因,这些基因编码的蛋白参与光合作用,是光合成反应中心II(photosystemII,PSII)的重要组成成分,在噬藻体感染蓝藻过程中可能发挥着重要的作用.一些假说认为这些基因可能来自于宿主并发生共进化.因此,光合作用基因的功能、起源与演变及基因多样性分布引起了人们的关注.

Many cyanophage isolates which infect the marine cyanobacteria Synechococcus spp.and Prochlorococcus spp.contain some genes homologous to psbA,psbD and hli,which code the proteins involved in photosynthesis and are key components of one of the photosynthetic reaction centers (photosystemII,PSII).These photosynthesis genes seem to be playing an important role during the process of infecting. Some hypotheses suggest that the acquisition possibilities of the gene from cyanobacterial host to phage and co-evolution with its host.Therefore,the origin and evolution,the diversity and the function of the genes attract growing attention.
