Draft genome sequence of Arthrospira platensis C1 (PCC9438)
Open accessAbstract
Arthrospira platensis is a cyanobacterium that is extensively cultivated outdoors on a large commercial scale for consumption as a food for humans and animals. It can be grown in monoculture under highly alkaline conditions, making it attractive for industrial production. Here we describe the complete genome sequence of A. platensis C1 strain and its annotation. The A. platensis C1 genome contains 6,089,210 bp including 6,108 protein-coding genes and 45 RNA genes, and no plasmids. The genome information has been used for further comparative analysis, particularly of metabolic pathways, photosynthetic efficiency and barriers to gene transfer.

A draft genome of a cold-resistant spirulina strain obtained from Solenoye Lake in Siberia did not identify any unique genes related to its tolerance of low temperatures, even though that strain displayed the maximum growth index at 20 °C, compared to the 30-35 °C of Asian, African, and South American strains.

Experimental — accuracy not yet measuredSeveral genomes from genus Arthrospira that belong to geographically distinct lineages have been nearly completely recovered by independent sequencing and assembly into single super-scaffolds, including A. platensis NIES-39, Arthrospira sp. PCC 8005 and A. platensis C1.
“In the past 6 years, several genomes from genus Arthrospira that belong to geographically distinct lineages have been nearly completely recovered by independent sequencing and assembly into single super-scaffolds, respectively, including A. platensis NIES-39, Arthrospira sp. PCC 8005 and A. platensis C1.”
From Whole genomic DNA sequencing and comparative genomic analysis of<i>Arthrospira platensis</i>: high genome plasticity and genetic diversity (2016) · cites this paper as [6]
The Genome project history section (page not provided) lists separate sequencing projects for NIES-39, PCC8005, and C1. Genome sequencing and assembly (page not provided) reports one scaffold with 63 gaps for C1, but does not establish single-super-scaffold assemblies for the other two strains. The copy also does not establish that the strains belong to geographically distinct lineages. (LLM, conf=0.85)
Experimental — accuracy not yet measuredUnlike other bacteria, the genome of microorganisms belonging to phylum Cyanobacterium generally possesses a large amount of dispersed repetitive sequences, particularly Arthrospira, thereby causing difficulty in the complete assembly of its genome.

In general, Siberian strains did not differ from tropical strains in terms of the presence of stress response genes.

From Spirulina/Arthrospira/Limnospira—Three Names of the Single Organism (2024) · cites this paper as [125]
The Genomic comparison section compares Arthrospira genomes, and the Insights from the genome sequence section discusses defense-related genes, but neither compares Siberian with tropical strains for stress-response genes. Searches for “Siberian,” “tropical,” and “stress response genes” found no passage addressing that comparison. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
