The full mitochondrial genomes of Mangalica pig breeds and their possible origin

Abstract

The mitogenomes of one animal of each of the three Mangalica breeds, Blonde, Red, and Swallow-belly were assembled from reads obtained by Next Generation Sequencing of the three genomes. Features of the mitogenomes were identical in the three breeds, apart from a second tRNA-Val gene on the L strand in Swallow-belly. Phylogenetic comparison of the three mitogenomes with 112 full mtDNA sequences clearly put Mangalicas into the European clade. Comparing the mitogenome of eight Mangalica animals revealed particular differences between them. The mitogenome of some Mangalicas was closely related to the Croatian Turopolje breed and this indicates either the common origin of their maternal lineages or admixture of some populations of the breeds. However, the origin of the mitogenome of certain purebred Mangalicas kept in the Hungarian Mangalica Gene Reserve still remains unknown.
