水牛（Bubalus bubalis）的繁殖仍然是一个讨论的问题，特别是如果这两种类型的家用水布法罗（沼泽和河流）来自不同的驯化事件，或者如果他们是人类选择的产物。为了获得更多的了解，我们分析了四个不同品种的80头水牛的整个线粒体D环区，即，在巴西和意大利采样的19头沼泽水牛（Carabao）和61头河流水牛（Murrah、Jafarabadi和地中海）。共检测到36种单倍型，128个多态位点。合并与东南亚和澳大利亚水牛公布的数据，并根据全面的中位数加入网络和人口统计学分析，我们显示的证据表明，河流和沼泽水牛体面从一个驯化事件，可能在印度次大陆。然而，今天的沼泽水牛有一个解开线粒体的历史，这可以解释为渗入野生水布法罗线粒体DNA到国内股票。我们也在讨论水牛在中国独立驯化的迹象。(C)2003年爱思唯尔公司All rights reserved.
The phylogeny of water buffaloes (Bubalus bubalis) is still a matter of discussion, especially if the two types of domestic water buffalo (swamp and river) derived from different domestication events or if they are products of human selection. To obtain more insight, we analyzed the entire mitochondrial D-loop region of 80 water buffaloes of four different breeds, i.e., 19 swamp buffaloes (Carabao) and 61 river buffaloes (Murrah, Jafarabadi, and Mediterranean), sampled in Brazil and Italy. We detected 36 mitochondrial haplotypes with 128 polymorphic sites. Pooled with published data of South-East Asian and Australian water buffaloes and based on comprehensive median-joining network and population demography analyses we show evidence that both river and swamp buffaloes decent from one domestication event, probably in the Indian subcontinent. However, the today swamp buffaloes have an unravelled mitochondrial history, which can be explained by introgression of wild water buffalo mtDNA into domestic stocks. We are also discussing indications for an independent domestication of buffaloes in China. (C) 2003 Elsevier Inc. All rights reserved.
