Abstract
ABSTRACTThe complete genome sequence of Cyanobacterium sp. strain HL-69 consists of 3,155,247 bp and contains 2,897 predicted genes comprising a chromosome and two plasmids. The genome is consistent with a halophilic nondiazotrophic phototrophic lifestyle, and this organism is able to synthesize most B vitamins and produces several secondary metabolites.

The genome of Cyanobacterium sp. strain HL-69 (CHL-69) consists of a circular chromosome (3,155,247 bp) with an average GϩC content of 37.8% and two plasmids, pCHL69-1 (86,432 bp) and pCHL69-2 (55,266 bp), with average GϩC contents of 34.1% and 35.32%, respectively
Average nucleotide identity (ANI) calculations showed that the HL-69 genome was 95.8% identical to that of the freshwater isolate Cyanobacterium sp. strain IPPAS B-1200 (3,410,249 bp)
Summary
The complete genome sequence of Cyanobacterium sp. strain HL-69 consists of 3,155,247 bp and contains 2,897 predicted genes comprising a chromosome and two plasmids. The genome of CHL-69 consists of a circular chromosome (3,155,247 bp) with an average GϩC content of 37.8% and two plasmids, pCHL69-1 (86,432 bp) and pCHL69-2 (55,266 bp), with average GϩC contents of 34.1% and 35.32%, respectively. Sequence analysis revealed 3,039 coding sequences, 9 rRNAs, and 44 tRNAs. The chromosome contained a putative prophage as well as a clustered regularly interspaced short palindromic repeat (CRISPR)-cas subtype I-D system.
