Chinese Academy of Agricultural Sciences decodes the mitochondrial genome of nematode for the first time

Recently, an innovative team of livestock parasitic diseases led by Zhu Xingquan, a researcher at Lanzhou Veterinary Research Institute of the Chinese Academy of Agricultural Sciences, decoded the mitochondrial genome of mandibular nematodes for the first time in the world, laying the foundation for molecular epidemiology, population genetics and systematic taxonomy of nematodes. The relevant research results are published in the international academic journal Science report.

It is reported that jaw mouth nematode is an important zoonotic parasitic nematode, but there is little research on its molecular biology. The innovative team of livestock parasitic diseases in Lanzhou Veterinary Institute used the traditional sequencing method to decode the mitochondrial genome of Echinostoma. The mitochondrial genome of Echinostoma is circular. Compared with other nematodes, the mitochondrial gene sequence of Echinostoma nematode was significantly rearranged. In addition, the phylogenetic tree of many kinds of animal and plant nematodes was constructed based on 12 mitochondrial protein coding genes. Based on the constructed phylogenetic tree, the position of submandibular order in nematode class was also discussed, and it was found that the relationship between submandibular order and Ascaris lumbricoides was closest.
