About the Molecular Palaeobotany and Evolution Group

In the Molecular Palaeobotany and Evolution Group (MPEG) led by Dr Sandy Hetherington we study the key innovations that enabled plants to colonise and radiate over the Earth’s surface.

Our current focus is to investigate the origin and evolution of the phloem, the food transport tissue in plants.

To investigate the evolution of the phloem and other key land plant innovations we combine evidence from fossils, studies of development from living species and comparative omics approaches.   

We are very well placed here in the Institute of Molecular Plant Sciences to carry out this research; with the great growth, omics and imaging facilities in the School of Biological Sciences and the brilliant collections of the two project partners, the living collections in the Royal Botanic Gardens Edinburgh and fossil collections in the National Museums of Scotland.
