TL;DR: At the 23-bp indel site, the genotype frequencies of Japanese Brown and Holstein breeds were similar to that of BSE affected cattle, and 12 different haplotypes were estimated from these genotypic data.
Abstract: Polymorphisms in the prion protein gene (PRNP) are known to be associated with transmissible spongiform encephalopathies in human, sheep and goats. There is tentative association between PRNP promoter polymorphism and bovine spongiform encephalopathy (BSE) susceptibility in cattle. In this study, we genotyped for six bovine PRNP polymorphic sites including a 23-bp indel in the promoter, a 12-bp indel in the intron 1, two nonsynonymous single nucleotide polymorphisms (SNPs), octapeptide repeats in the coding region and a 14-bp indel in the 3'-untranslated region in 178 animals representing Japanese Brown, Kuchinoshima feral, Mishima, Japanese Shorthorn and Holstein. In 64 Japanese Brown cattle, three indel sites were polymorphic. All of the six sites were monomorphic in Kuchinoshima. The 23-bp and 12-bp indel sites were polymorphic in Mishima cattle. The 23-bp and 14-bp indel sites were polymorphic in Japanese Shorthorn cattle. Both SNP sites were monomorphic in all cattle examined in this study. At the 23-bp indel site, the genotype frequencies of Japanese Brown and Holstein breeds were similar to that of BSE affected cattle. We estimated 12 different haplotypes from these genotypic data. A '23-12-K6S14+' haplotype was the major haplotype in all populations, whose frequencies ranged from 0.50 to 1.00.

TL;DR: The craniometrical multivariate analysis supported to the northern route theory of the origin of Mishima cattle, which has been postulated as the only pure representative breed of native Japanese cattle, and was very important for theorigin of "Wagyu" (native Japanese cattle).
Abstract: The present study on measurement of the skull of Mishima cattle, which has been postulated as the only pure representative breed of native Japanese cattle, was performed using craniometrical multivariate analysis. The data of the skull of Mishima cattle was compared with 17 breeds of cattle, i.e. Korean cattle (Hamhung, Pyongyang, Chinju Suwon, and Kwangju), Mongolian cattle, Hainan Tao cattle, northeastern Chinese cattle (Shuangliao, Shenyang, Tongliao, Luta, and Chilin), Astatic Water Buffalo, Yak, Bos Banteng, American Bison, and Holstein-Friesian. The Mishima cattle was included in the group of Korean breeds, especially it was closed on the group of Pyongyang and Chinju breeds. The distance on the craniometrical multivariate analyzing co-ordinate between Mishima cattle and Hainan Tao breed of Zebu cattle was larger than the distance between Mishima cattle and Korean breeds. While result, as a above the present study was very important for the origin of "Wagyu" (native Japanese cattle). Since the northern route theory of the origin of Mishima cattle has been reported on the type of serum enzymes and hemotypes. It was suggested that the craniometrical multivariate analysis supported to the northern route theory of the origin of Mishima cattle.

TL;DR: 1995年, 見島に飼育されていた雌牛 頭数は89頭で, これらは6つの母系に分類された.
Abstract: 1995年, 見島に飼育されていた雌牛頭数は89頭で, これらは6つの母系に分類された. 6系統のうち5系統から各2頭ずつ選び, ミトコンドリアDNAのD-loop領域における塩基配列を調べた結果, その変異から見島牛母系は2つのハプロタイプに分類された. すなわち, よしまき系, かめきち系, たかただ系の3系統はM1に, みまつ系, しらうめ系の2系統はM2に分類された. このように見島牛母系5系統は2つの遺伝子型に集約され, 遺伝的多様性はきわめて小さいことが明らかになった. M2に分類された母系の遺伝子頻度は, 見島牛雌牛全体の14.6%を占めるに過ぎず, 早急の保護対策が必要であると思われる.

TL;DR: Se sequenced 16 Mongolian cattle genomes and compared them to the 92 genomes of 10 representative breeds worldwide to help understand the evolutionary history and formation process of the breeds and provide theoretical materials regarding the genetic mechanism underlying breed characteristics and molecular breeding programmes of the taurine clades in the future.
Abstract: European taurine and East Asian taurine are two main clades in Bos taurus, but their genomic differences are not clearly elucidated. Here, we sequenced 16 Mongolian cattle genomes and compared them to the 92 genomes of 10 representative breeds worldwide. We found the highest LD level in Mishima cattle and the fastest LD decay in European taurine. Phylogenetic analysis revealed that Mongolian, Hanwoo and Mishima cattle were clustered into East Asian taurine. From selective sweep, gene annotation, functional enrichment and differential expression analysis, we identified selective signals including genes and/or pathways related to rapid growth and large body size in European taurine, and superior meat quality in East Asian taurine. Our findings will help us understand the evolutionary history and formation process of the breeds and provide theoretical materials regarding the genetic mechanism underlying breed characteristics and molecular breeding programmes of the taurine clades in the future.
