Xiaonan Wang, Jiaqi Wu, Takahiro Yonezawa, Zhumei Ren
TL;DR
This paper reports the full mitochondrial genome of a gall-forming aphid and its evolutionary relationship with other aphids that feed on the same host plant.
Contribution
The study provides the first complete mitochondrial genome sequences for Chaetogeoica ulmidrupa and clarifies its phylogenetic position.
Findings
The mitochondrial genome of C. ulmidrupa has a strong A+T bias and specific gene start and stop codon patterns.
C. ulmidrupa is phylogenetically closely related to C. yunlongensis and Slavum lentiscoides, which all form galls on P. chinensis.
Abstract
We sequenced two complete mitochondrial genomes of Chaetogeoica ulmidrupa, a gall-forming aphid on Pistacia chinensis. Each genome consists of 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a control region, with a strong A+T bias (∼85%). All protein-coding genes initiate with ATN codon and terminate with TAA, except for ND4 and COX1 ending with a single T. Phylogenetic analysis strongly supported that C. ulmidrupa was sister to C. yunlongensis and together they formed a clade with Slavum lentiscoides, all three species of which feed on the primary host plant P. chinensis to form galls.
