Evolution and variation of the nifD and hupL elements in the heterocystous cyanobacteria.

International journal of systematic and evolutionary microbiology - 1 Dec 2011

Henson Brian J, Hartman Linda, Watson Linda E, Barnum Susan R

Abstract excerpt

In heterocystous cyanobacteria, heterocyst differentiation is accompanied by developmentally regulated DNA rearrangements that occur within the nifD and hupL genes, referred to as the nifD and hupL elements. These elements are segments of DNA that are embedded within the coding region of each gene and range from 4 to 24 kb in length. The nifD and hupL elements are independently excised from the genome during the...
