Cystis and Nostoc at 8.4 (28.1 ) and 9.8 (36.1 ), respectively. Another possible influence on the expansion is the presence of duplicate copies of recA, an important multifunctional DNA repair and recombination enzyme found in nearly every organism (reviewed in ref. 22). There are an astounding seven distinct copies of this gene (recA) found in the A. marina genome, far greater than the previous

Itrogen cycles in each of these environments where they modify their morphology, metabolism, and light-harvesting systems for survival in their respective niches. To date, genomes of 55 cyanobacterial strains in 21 genera have been completed or are under construction (National Center for Biotechnology Information). These cyanobacterial genomes are diverse in size, ranging from 1.66 to 9.1 Mbp. The
He global population of Acaryochloris species has a range of lifestyles from free-living to symbiotic and marine to terrestrial. We report here the complete genome sequence of A. marina str. MBIC11017, the first A. marina strain isolated from the Prochloron-dominated colonial ascidian Lissoclinum patella off the tropical coast of the Palau islands (3, 5). This represents a previously uncharacteriz
