Abstract

We examined the gene expression levels of equinatoxin and equistatin in the sea anemone Actinia equina, when reared at varying environmental temperatures for five months. Both genes were significantly downregulated at 10 °C compared to 16 °C but showed no significant change at 22 °C. This provides the first evidence of an effect of temperature on gene expression, but with no effect of increasing temperatures such as those predicted due to climate change.

摘要

我们检测了在不同环境温度下饲养五个月的海葵（Actinia equina）中刺海葵毒素和海葵抑肽的基因表达水平。与16°C相比，这两种基因在10°C时均显著下调，但在22°C时无显著变化。这首次证明了温度对基因表达有影响，但对诸如气候变化预测的温度升高没有影响。
