钝顶节旋藻（Arthrospira（Spirulina）platensis）是一种丝状非固氮蓝藻，是工业应用和食品供应的重要生物。几乎全基因组的A. Platensis NIES-39在本研究中测定。A.根据光学作图，估计Platensis是一条6.8 Mb的单一环状染色体。注释这6.7 Mb的序列产生6630蛋白质编码基因，以及两套rRNA基因和40 tRNA基因。在蛋白质编码基因中，78%与其他生物相似;其余22%目前未知。基因组的总长度为612 kb，包括II组内含子、插入序列和一些重复元件。I组内含子位于蛋白质编码区。确定了丰富的限制修饰系统。在基因组成的独特功能，特别是在大量的基因腺苷酸环化酶和溶血素样钙结合蛋白和趋化蛋白。通过比较基因组学分析突出了细丝特异性基因。
A filamentous non-N2-fixing cyanobacterium, Arthrospira (Spirulina) platensis, is an important organism for industrial applications and as a food supply. Almost the complete genome of A. platensis NIES-39 was determined in this study. The genome structure of A. platensis is estimated to be a single, circular chromosome of 6.8 Mb, based on optical mapping. Annotation of this 6.7 Mb sequence yielded 6630 protein-coding genes as well as two sets of rRNA genes and 40 tRNA genes. Of the protein-coding genes, 78% are similar to those of other organisms; the remaining 22% are currently unknown. A total 612 kb of the genome comprise group II introns, insertion sequences and some repetitive elements. Group I introns are located in a protein-coding region. Abundant restriction-modification systems were determined. Unique features in the gene composition were noted, particularly in a large number of genes for adenylate cyclase and haemolysin-like Ca2+-binding proteins and in chemotaxis proteins. Filament-specific genes were highlighted by comparative genomic analysis.
