| the mitochondrial cytochrome oxidase subunit i gene occurs on a minichromosome with extensive heteroplasmy in two species of chewing lice, geomydoecus aurei and thomomydoecus minor. | in animals, mitochondrial dna (mtdna) typically occurs as a single circular chromosome with 13 protein-coding genes and 22 trna genes. the various species of lice examined previously, however, have shown mitochondrial genome rearrangements with a range of chromosome sizes and numbers. our research demonstrates that the mitochondrial genomes of two species of chewing lice found on pocket gophers, geomydoecus aurei and thomomydoecus minor, are fragmented with the 1,536 base-pair (bp) cytochrome-ox ... | 2016 | 27589589 |
| host behaviour drives parasite genetics at multiple geographic scales: population genetics of the chewing louse, thomomydoecus minor. | pocket gophers and their symbiotic chewing lice form a host-parasite assemblage known for a high degree of cophylogeny, thought to be driven by life history parameters of both host and parasite that make host switching difficult. however, little work to date has focused on determining whether these life histories actually impact louse populations at the very fine scale of louse infrapopulations (individuals on a single host) at the same or at nearby host localities. we used microsatellite and mt ... | 2015 | 26152795 |
