Abstract

Arthrospira (Spirulina) platensis is a well-known commercial cyanobacterium that is used as a food and in feed supplements. In this study, we examined the physiological changes and whole-genome expression in A. platensis C1 exposed to high temperature. We found that photosynthetic activity was significantly decreased after the temperature was shifted from 35°C to 42°C for 2 h. A reduction in biomass production and protein content, concomitant with the accumulation of carbohydrate content, was observed after prolonged exposure to high temperatures for 24 h. Moreover, the results of the expression profiling in response to high temperature at the designated time points (8 h) revealed two distinct phases of the responses. The first was the immediate response phase, in which the transcript levels of genes involved in different mechanisms, including genes for heat shock proteins; genes involved in signal transduction and carbon and nitrogen metabolism; and genes encoding inorganic ion transporters for magnesium, nitrite and nitrate, were either transiently induced or repressed by the high temperature. In the second phase, the long-term response phase, both the induction and repression of the expression of genes with important roles in translation and photosynthesis were observed. Taken together, the results of our physiological and transcriptional studies suggest that dynamic changes in the transcriptional profiles of these thermal-responsive genes might play a role in maintaining cell homeostasis under high temperatures, as reflected in the growth and biochemical composition, particularly the protein and carbohydrate content, of A. platensis C1.

  • Testing spirulina reactions to high temperature, a shift from 35 °C to 42 °C for 2, 8, and 24 h, revealed two distinct phases for the responses: an immediate response phase and a long-term response phase.

    “An example was the testing of spirulina reactions to high temperature, a shift from 35 °C to 42 °C for 2, 8, and 24 h. The results of the expression profiling in response to heat stress revealed two distinct phases for the responses.”

    From Spirulina/Arthrospira/Limnospira—Three Names of the Single Organism (2024) · cites this paper as [137]

    The Physiological response to thermal change section reports a shift from 35 °C to 42 °C and measurements extending to 24 h. The Identification of differentially expressed genes section identifies immediate and long-term expression-response phases, but the Additional information section says expression profiling used 20, 60, 120, 240 and 480 min samples—not 2, 8 and 24 h samples. The cited sentence conflates the physiological observation times with the expression-profiling time points. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • In the long-term response phase, both the induction and repression of genes with important roles in translation and photosynthesis have been observed.

    “In the second, long-term response phase, both the induction and repression of genes with important roles in translation and photosynthesis have been observed [137].”

    From Spirulina/Arthrospira/Limnospira—Three Names of the Single Organism (2024) · cites this paper as [137]

    The Discussion (page unavailable) reports that genes involved in translation and photosynthesis were repressed during the long-term response to high temperature. The paper also reports later induction of some genes, but the retrieved passages do not identify those as translation- or photosynthesis-related, so the induction portion of the claim is not supported. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • In the immediate response phase, the transcript levels of genes involved in different mechanisms, including genes for heat shock proteins, signal transduction, carbon and nitrogen metabolism; inorganic ion transporters were either transiently induced or repressed by heat.

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.
