Multicellular plants and animals which characterise the modern biosphere are but a recent addition to the diversity of life on the Earth. For approximately 3 billion years of Earth’s history, the land masses were colonised exclusively by microorganisms. For these early colonisers, the rocks which comprise the planet’s crust were an essential source of nutrients without which the Earth’s surface would have been uninhabitable. I have used a technique known as proteomics to investigate the cellular mechanisms involved in nutrient uptake from volcanic rock. I will discuss the results of this study with particular emphasis on the apparent requirement for tight regulatory control on both toxic heavy metals and essential nutrients in rocky environments.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
