Professor Colin Osborne, Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK. New research in the lab investigates how plant growth is controlled by the supply of carbon from photosynthesis (source strength) verses the demand for carbon in growing tissues (sink strength).
Horticulture is a highly valuable industry within the Australian agricultural sector. Tree crops account for half of the horticulture industry’s value, with mango, macadamia, avocado, almond and citrus being the major Australian horticultural tree crops.
Projects are available in the following areas. Stress responses in crops and sustainable biomass production and processing. The project aims at elucidating several aspects of the control of plant defences and to identify environmentally friendly forms of plant protectants, leading to enhanced crop yields.
Our research is focused on the biogenesis of chloroplasts and other plastids in plants, particularly in relation to the import of nucleus-encoded proteins and the role of the ubiquitin-proteasome system.
Crop rotations have been at the centre of agricultural systems throughout history. In modern agriculture, the main purpose of rotating crops is to reduce the incidence of diseases, pests or weeds that are difficult to control with pesticides.
Fungal pathogens cause disease in crop plants dramatically reducing yields and quality. Preventing fungal disease in crops would ensure global food security and reduce agricultural inputs with respect to fungicide application.
