Research focus

My interest is in the regulation of nutrient uptake and homeostasis in plants. My lab uses iron nutrition responses as experimental system to identify the roles of new genes and proteins involved in the signalling of the iron nutrition status. Upon iron deficiency specific molecular and physiological responses are induced that serve to increase the acquisition and internal mobilization of iron. We have been exploring the genetic and biochemical interactions of transcription factors that control networks of iron-regulated genes mediating uptake and distribution of iron. We have been studying iron transport and homeostasis mechanisms during plant development. We will utilise our knowledge to investigate the differences in nutrient use efficiency in perennials versus annuals.
