Project description:This study provides a mitochondrial complete genome of Schizothorax davidi. The complete genome is 16,576 bp in length with an A + T content of 54.9%, which contains 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. The phylogenetic analysis indicated that S. davidi is closely related to Schizothorax lissolabiatus. These results contribute to explore the adaptation strategy of S. davidi on the conditions of Qinghai-Tibet Plateau.
Project description:Isolated and established in culture from the Antarctic in 1988, the nematode Panagrolaimus davidi has proven to be an ideal model for the study of adaptation to the cold. Not only is it the best-documented example of an organism surviving intracellular freezing but it is also able to undergo cryoprotective dehydration. As part of an ongoing effort to develop a molecular understanding of this remarkable organism, we have assembled both a transcriptome and a set of genomic scaffolds. We provide an overview of the transcriptome and a survey of genes involved in temperature stress. We also explore, in silico, the possibility that P. davidi will be susceptible to an environmental RNAi response, important for further functional studies.
