Heterocyst pattern formation controlled by a diffusible peptide.

Science (New York, N.Y.) - 30 Oct 1998

Yoon H S, Golden J W

Abstract excerpt

Many filamentous cyanobacteria grow as multicellular organisms that show a developmental pattern of single nitrogen-fixing heterocysts separated by approximately 10 vegetative cells. Overexpression of a 54-base-pair gene, patS, blocked heterocyst differentiation in Anabaena sp. strain PCC 7120. A patS null mutant showed an increased frequency of heterocysts and an abnormal pattern. Expression of a patS-gfp...
