PatS and products of nitrogen fixation control heterocyst pattern.

Journal of bacteriology - 1 Apr 2001

Yoon H S, Golden J W

Abstract excerpt

The filamentous cyanobacterium Anabaena sp. strain PCC 7120 forms a developmental pattern of single heterocysts separated by approximately 10 vegetative cells. Heterocysts differentiate from vegetative cells and are specialized for nitrogen fixation. The patS gene, which encodes a small peptide t...
