摘要

Genes responsible for conferring mineral phosphate solubilizing (mps) ability were cloned from Synechocystis PCC 6803, a unicellular cyanobacterium, which by itself does not show mps ability. Escherichia coli was transformed with the genomic DNA library of the Synechocystis PCC 6803 and two mps genes were selected based on the ability of the transformants to show zone of clearance on solid medium containing dicalcium phosphate (DCP) as the sole source of phosphorus (P). The mps phenotype was found to be plasmid-associated as shown by transformation of E. coli strain with isolated plasmids. These transformants also solubilized rock phosphate. [References: 12]
