Characterization of Synechocystis sp. strain PCC 6803 and Δnbl mutants under nitrogen-deficient conditions

Abstract

The impact of nitrogen deficiency on the unicellular cyanobacterium Synechocystis sp. strain PCC 6803 and three nbl (non-bleaching) mutants (ΔnblA1, ΔnblA2 and ΔnblB) was investigated. The ΔnblA mutants entered a non-dividing, dormant state soon after the initiation of nitrogen starvation. The cells became larger, the membrane system was disorganized, and… (More)
