Genetic and hormonal control of root meristem function
Abstract: Plant development contrasts with animal development by exhibiting a high degree of flexibility (plasticity), in which final form is unpredictable. This plasticity represents a mechanism for responding to environmental change, such as variations in availability of water, nutrients, light, or attack by herbivores. While animals respond to such environmental challenges through behavioural change, plants use plasticity in development to adapt and survive, and this is mediated to a significant extent through the activity of meristems. These are localized regions of cell division that contain stem cell-like cells, and maintain cellular pattern (that typically originates in the embryo) and undergo division for growth. In this talk I will present some of our work on the genetic and signalling mechanisms that control meristem identity and activity, using Arabidopsis root development as a model system.
Biography: Keith Lindsey is Professor of Plant Molecular Biology and Head of Department at Durham University’s Department of Biosciences. Keith graduated in Botany from St. Catherine's College, Oxford and carried out his PhD at Edinburgh University's Department of Botany. He also carried out post-doctoral research at Edinburgh University and then at the Department of Biochemistry at Rothamsted Experimental Station. He was appointed to an academic post at the University of Leicester in 1989, before moving to a Chair in Durham in 1996. His research interests are in understanding mechanisms in plant development, using molecular genetic methods, and more recently, mathematical modelling and systems biology approaches. He has been a member of the governing Council for the BBSRC; the UK Government Advisory Committee on Releases to the Environment (ACRE); is Chair of the New Phytologist Trust and editor for New Phytologist; and until recently, was President and Chair of Council of the Society for Experimental Biology. He has also previously been Chair of the Multinational Arabidopsis Steering Committee (MASC).
