Complete mitochondrial genomes of the hemiparasitic genus Cymbaria (Orobanchaceae): insights into repeat-mediated recombination, phylogenetic relationships, and horizontal gene transfer.

ABSTRACT:

Background

The Orobanchaceae family is widely recognized as an exemplary model system for examining the evolutionary dynamics of parasitic plants. However, reports on the mitochondrial genome (mitogenome) of the hemiparasitic tribe Cymbarieae are currently lacking. Here, we sequenced, assembled and characterized the complete mitogenome of the genus Cymbaria L. sensu stricto (C. mongolica and C. daurica).

Results

A total of 51 unique mitochondrial genes, including 33 protein-coding genes, three rRNA genes, and 15 tRNA genes, are shared by the mitogenomes of the two hemiparasitic plants, exhibiting the gene content characteristic of autotrophic plants. The mitogenomes of C. mongolica and C. daurica are characterized by a pentacyclic chromosome structure (their major conformati
