Antarctic waters are the largest almost untapped diversified resource of our planet. Molecular resources for Antarctic organisms are very limited and mostly represented by sequences used for species genotyping. In this study, we present the first transcriptome for the copepod , one of the predominant zooplankton species of Antarctic waters. This transcriptome represents also the first molecular resource for an eucalanoid copepod. The transcriptome is of high quality and completeness. The presence of three predicted genes encoding antifreeze proteins and gene duplication within the glutathione metabolism pathway are suggested as possible adaptations to cope with this harsh environment. The transcriptome represents a powerful new resource for investigating the molecular basis associated with polar biological processes and ecology.
南极水域是地球上最大的几乎未被开发的多样化资源。南极生物的分子资源非常有限，主要以用于物种基因分型的序列为代表。在本研究中，我们展示了桡足类动物的首个转录组，桡足类是南极水域主要的浮游动物物种之一。这个转录组也是真哲水蚤类桡足动物的首个分子资源。该转录组具有高质量和完整性。存在三个预测的编码抗冻蛋白的基因以及谷胱甘肽代谢途径中的基因复制，这被认为是应对这种恶劣环境的可能适应方式。该转录组是研究与极地生物过程和生态相关分子基础的强大新资源。
