To understand the origin and genetic diversity of Italian horses, mitochondrial DNA D-loop sequences were generated for 163 horses from seven breeds. Sequence analysis of a 480-bp segment revealed a total of 84 haplotypes with 57 polymorphic sites, indicating multiple maternal origins and high genetic diversity. Comparison of the haplotypes with the equine mtDNA haplotype/haplogroup nomenclature showed a haplogroup distribution in the Italian breeds more similar to that found in the Middle East breeds than in the European breeds, probably due to the economic and cultural relationship with the Middle East in the past centuries.
为了解意大利马的起源和遗传多样性，对来自七个品种的163匹马的线粒体DNA D环序列进行了测定。对一段480个碱基对片段的序列分析显示，共有84个单倍型，57个多态性位点，表明其具有多个母系起源和较高的遗传多样性。将这些单倍型与马的线粒体DNA单倍型/单倍群命名法进行比较，发现意大利品种中的单倍群分布与中东品种更为相似，而不是欧洲品种，这可能是由于过去几个世纪与中东的经济和文化关系所致。
