Dr H Zhang
Applications accepted all year round
Competition Funded PhD Project (UK Students Only)
About the Project
The root system of higher plants performs vital functions such as water and nutrient uptake and physical anchorage. It is formed through a continuous developmental process that lasts the entire life-span of a plant. This developmental process depends on the ability of plants not only to make new roots but also to maintain a group of mitotically competent cells in a specific region, known as the root meristem, at the tip of an existing root. The project is to investigate the mechanism underlying root meristem maintenance in the model plant Arabidopsis using a unique set of mutants and specific cell identity markers. The project involves a range of molecular, genetic and confocal imaging techniques and particularly suits highly motivated and research career-orientated students.
