Dr Stuart Fraser
I am working to understand the epidemiology and life cycle of Uromycladium acaciae, the causal agent of a serious rust (Puccinales) disease in Acacia mearnsii (black wattle) plantations in southern Africa. Very little is known about this pathogen species or other species within the Uromycladium genus. Interestingly, this pathogen may have been present in South Africa since at least the mid-late 1980s, however it was not observed causing significant damage until 2013. The recent emergence of the disease has co-occurred with the appearance of the telial life stage of the pathogen. Research will therefore focus on both basic disease epidemiology, as well as understanding the pathogen’s life cycle. Early research will aim to investigate the importance of environmental factors on disease severity and pathogen life cycle. While, later research will aim to investigate the importance of host and pathogen factors. This research will not only have important implications for control of the disease, but will also improve our knowledge of rust lifecycles.
Before moving to FABI, I read BSc Ecology at the University of Sheffield, where my final year projects included, 1. looking at local adaptation in seed size, and 2. predator impacts on the behaviour and morphology of water fleas (Daphnia). For my MSc dissertation (Conservation and Forest Protection, Imperial College London) I worked on local adaptation in the germination requirements of Eucalyptus obliqua and its impact on the susceptibility of this species to climate change (University of Melbourne). Finally whilst studying for my PhD thesis (Forestry, University of Aberdeen) I moved over to plant pathology, working on variation in host susceptibility to dothistroma needle blight, caused by Dothistroma septosporum, within species commonly used in British forestry.
