Abstract:
Plectus murrayi is a free-living microbivorous nematode endemic to Antarctic soils. Our draft assembly of its mitogenome was 15,656 bp long, containing 12 protein-coding, eight transfer RNA (tRNA), and two ribosomal RNA (rRNA) genes. Mitophylogenomic analyses extend our understanding of mitochondrial evolution in Nematoda.
Insights
The draft genome of the Antarctic nematode Plectus murrayi was sequenced, revealing its mitochondrial DNA structure. This research enhances our understanding of mitochondrial evolution in nematodes.
