A laboratory competency examination in microbiology.

abstract：:DNA hybridization using the Synechocystis PCC6803 glucose transporter gene, glcP, revealed a single homologous region in two facultative photoautotrophic strains out of three tested, and none in three obligate autotrophs. In one of the latter, Synechococcus PCC7942, integration of glcP into the chromosome resulted in ...
