We study evolution of organisms at the genomic levels through computer analyses and genome sequencing. We are particularly interested in primate and human evolution. Themes of our study are quite diverse as follows.
# Analysis of genome evolution: We study lineage-specific highly conserved DNAs at different levels of organism groups, such as vertebrates, mammals, primates, and whole eukaryotes.
# DNA analysis of human populations: We study genetic affinities of modern humans with special reference to those in Asia. We are also involved in various ancient genome analyses of human remains.
# Development of nucleotide sequence analysis methods: We developed new system MISHIMA which can multiply align many bacrterial genome-size sequences.
# Other themes: blood group gene evolution, duplicated gene evolution, and analysis of introgression between closely related primate species.

Exactly 50 years ago, today in 1968, Dr. Motoo Kimura, then Head (later Professor) at Division of Population Genetics, National Institute of Genetics, published one paper titled "Evolutionary rate at the molecular level" in Nature, vol. 217, pp. 624-626. In this paper, he proposed "the Neutral Theory" that is now the core of the modern evolutionary theory.
To celebrate the 50th anniversary of the Neutral Theory proposal, SMBE2018 will be held in Yokohama, Japan.

What's new

July 8th-12th 2018

SMBE annual meeting will be held in Yokohama, Japan this year. Prof. Saitou is one of organizing committee members.
Jun 2nd 2018

We will have special symposium to celebrate over 50,000 Google Scholar citations of Saitou & Nei's (1987) neighbor-joining method paper at National Institute of Genetics. Twenty researchers will present their studies.

April 18th-20th 2018

Prof. Saitou will give an invited talk "Genome diversity is central to natural history studies"at "AsiaEvo Conference" in Sheraton Dameisha Resort, Shenzhen, China.

March 17th 2018

Prof. Saitou will give an invited talk "Swift neighbor-joining method for massive genome sequence data."at "Schull Institute Annual Conference and Scholars Program" in Center for Science and Health Professions Building, University of St. Thomas, Houston, USA.

February 6th 2018
Saitou and Nei (1987; Molecular Biology and Evolution, vol. 4, pp. 406-425), which proposed neighbor-joining method based on Ph.D. work conducted by Professor Saitou at Univ. Texas at Houston, exceeded 50,000 citations according to Google Scholar.
