Abstract excerpt

Evident differentiation of vegetative cells into heterocysts in Anabaena sp. strain PCC 7120 is prevented by insertions in genes hetR and hetP. Nostoc ellipsosporum possesses single copies of genes that hybridize with hetR and hetP. In mutant NE2 of N. ellipsosporum, in which hetR is interrupted...
