Tracy Valentine
Tracy has over 20 years experience in applied and basic research at the plant root:soils interface. Utilising both image analysis and molecular based methods she has investigated processes and impacts of soil management on plant root growth and development, and root soil biological and physical interactions with the aim of understanding how to improve crop genotypes and management systems, via increasing knowledge of root:soil biological and physical processes at a range of scales.
Current research interests
-
• Understanding how changes in agriculture impact on the performance of crop plants, as well as the impact of the management on soils is key to developing more sustainable farming practices in terms of crop yield, long-term soils sustainability and farm income sustainability.
• Research includes:
o Mechanistic understanding of the individual root elongations
o Phenotyping of root traits including root architecture
o Mechanistic understanding of root interactions with soil structure
o Understanding impact of crop management (e.g. soil tillage and crop rotations) on soil and root:soil interactions
o High resolution and multispectral imaging and image analysis
o Whole plant phenotyping and
o Impact of soil restrictions on plant performance and ecosystem impacts
o Impact of crop cultivar variation on root:soil interactions.
o Utilisation of confocal microscopy and computer vision techniques to develop tools for measuring cell expansion, seed biology and root elongation.
