Title |
Bioinformatic Analyses Reveal Microbial Adaptation to Environmental Changes and Transport across Sea, Land, and Sky
|
Abstract |
Microbes are present nearly everywhere on the Earth and frequently affected by geological and meteorological phenomena
(e.g. earthquakes and tsunami, and wind and precipitation). Such phenomena lead to drastic changes in habitat environment
and microbial transport through long distance and/or between different habitat types. Thanks to the recent improvements of
sequencing technologies, it has become easier to sequence microbial genomes and to investigate genetic variations in
microbes and whole-community diversity in various environments. However, observations of microbial adaptation at the
genomic level and microbial transport using culture-independent methods are still lacking. In this presentation, I will
introduce two studies titled "Genomic and Metagenomic Analysis of Microbes in a Soil Environment Affected by The 2011
Great East Japan Earthquake Tsunami" and "Seasonal Analysis of Microbial Communities in Precipitation Suggests Long-
Distance Atmospheric Microbial Transport and Deposit via Precipitation". These studies provide new insights into
microbial adaptation and transport in natural environment.
