Heat shock protein synthesis and thermotolerance in Cataglyphis, an ant from the Sahara desert.
Open accessAbstract
The ant Cataglyphis lives in the Sahara desert and is one of the most thermotolerant land animals known. It forages at body temperatures above 50 degrees C, and the critical thermal maxima are at 53.6 +/- 0.8 degrees C for Cataglyphis bombycina and 55.1 +/- 1.1 degrees C for Cataglyphis bicolor. The synthesis and accumulation of heat shock proteins (HSPs) were analyzed in Cataglyphis and compared to Formica, an ant living in more moderate climates, and to two Drosophila species. In Cataglyphis, protein synthesis continues at temperatures up to 45 degrees C as compared to 39 degrees C for Formica and Drosophila. The two Drosophila species, Drosophila melanogaster and Drosophila ambigua, differ with respect to their maximal induction of HSP synthesis and accumulation by 3-4 degrees C. In contrast, the two ant species accumulate HSPs prior to their exposure to heat, and in Cataglyphis the temperature of maximal HSP induction by de novo protein synthesis is only 2 degrees C higher than in Formica. These findings are interpreted as preadaption of the ants prior to exposure to high temperatures.

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.
