【演 題】Comparative genomics: new insights into evolutionary adaptation in
response to environmental change
【講 師】Prof. Joong-Ki Park
Division of EcoScience, Ewha Womans University, Korea
【要 約】
Evolutionary adaptation is the process that living organisms become adjusted
to a new environment and it often entails acquisition and/or modification of
their genotypic and/or phenotypic traits in response to a variety of biotic
and/or abiotic factors in new environments. Due to innovation and rapid advances
in DNA sequencing technologies and bioinformatics tools, decoding whole genome
sequencing can be possible at a reasonable cost and timeframe. This makes it
possible to understand the evolution of complex animal life at the level of
genomic architecture. In the first part of my talk, I will focus on one of the
comparative population genomic studies that uncover contrasting demographic
changes of two closely related dolphin species in the last glacial. Population
genomic data can be used to infer historical effective population sizes (Ne),
which help study the impact of past climate changes on biodiversity. Comparative
population genomic analysis of these two closely related species with some
different habitat preference exhibit contrasting demographic changes in the last
glacial, likely through actual changes in population size and/or alterations in
the level of gene flow among populations. In the second part, I will present
some of other comparative genomic project addressing some genomic signatures of
deep sea mussel species that are associated with their successful adaptation to
unfavorable, toxic environment.
