The mitochondrial genomes of two Gryllus crickets (Grylloidea: Gryllidae) via RNA-seq.

Here, we used RNA-seq reads to assemble the complete mitochondrial genomes of the spring field cricket, Gryllus veletis , and the variable field cricket, Gryllus lineaticeps. The mitochondrial genomes of G. veletis (15,686 bp, MW322713) and G. lineaticeps (15,607 bp, MW315773) each contain the expected 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a large control (D-loop) region. The arrangements of these features were similar for both species and consistent with other closely related Orthoptera. A phylogenetic analysis of the mitochondrial genome sequences revealed that G. veletis and G. lineaticeps cluster with the other Gryllus species and all reside in a clade with the Gryllidae.
