Mutations in hik26 and slr1916 lead to high-light stress tolerance in Synechocystis sp. PCC6803.

Abstract excerpt

Increased tolerance to light stress in cyanobacteria is a desirable feature for their applications. Here, we obtained a high light tolerant (Tol) strain of Synechocystis sp. PCC6803 through an adaptive laboratory evolution, in which the cells were repeatedly sub-cultured for 52 days under high light stress conditions (7000 to 9000 μmol m-2 s-1). Although the growth of the parental strain almost stopped when...
