Towards adaptive evolution of organisms to extremes of pressure and temperature
イベント種類 セミナー
対象 教職員向け 大学院生向け 学部生向け
イベント概要 講 師: Prof. Pradeep Kumar(Universisy of Arkansas, Department of Physics)

Both prokaryotic and eukaryotic microbes thrive under a staggering array of diverse environmental conditions including high pressures and extremes of temperature. High pressure and temperature present biophysical challenges to cells. Thus, cellular growth and survival for organisms living under these extreme conditions are likely maintained by subtle adaptations of their bio-molecular machinery, thus optimizing molecular function for each particular environmental challenge. In this talk, I will discuss the recent progress made in our lab towards understanding the effect of high pressure and temperature on the cellular processes including cell division, transcription, and metabolism of a model prokaryote and an eukaryote. Furthermore, I will discuss a few preliminary results from the experiments of adaptive evolution of a model prokaryote and eukaryote to the extremes of environmental conditions.
