Analysis of a Het- mutation in Anabaena sp. strain PCC 7120 implicates a secondary metabolite in the regulation of heterocyst spacing.

Journal of bacteriology - 1 Apr 1994

Black T A, Wolk C P

Abstract excerpt

Transposon-generated mutant N10 of Anabaena sp. strain PCC 7120 has a Het- phenotype (A. Ernst, T. Black, Y. Cai, J.-M. Panoff, D. N. Tiwari, and C. P. Wolk, J. Bacteriol. 174:6025-6032, 1992). Reconstruction of the transposon mutation reproduced a Het- phenotype, but reconstructions with other insertions at the position of the transposon produced strains that form multiple contiguous heterocysts.
