Dr Tim O'Hare

Senior Research Fellow, CNAFS

Dr Tim O’Hare is a plant physiologist researching the development and biofortification of fruit, nuts and vegetables with naturally enhanced health benefits, in particular carotenoid, glucosinolate, and mineral-based phytonutrients (Zn, Se).

Current projects include the development of high-zeaxanthin sweetcorn (see story) as a dietary protective measure against macular degeneration (AMD), tropically-adapted high-lycopene tomatoes for prostate cancer, and zinc/selenium biofortification of macadamia nuts. 

With a background in fruit physiology and biotechnology, his expertise lies in determining the physiological, biochemical and genetic limitations to enhancing phytonutrient concentration in popular fruit, nut and vegetables.

His research combines the disciplines of plant breeding and molecular analysis, phytonutrient compositional analysis, pre-harvest and postharvest factors affecting phytonutrient accumulation, and biofortification’s impact on product quality.

'SuperGold' corn to slow major eye disease

16 Dec 2013
New sweet corn varieties developed by the Department of Agriculture, Fisheries and Forestry
(DAFF) and UQ's Queensland Alliance for Agriculture and Food Innovation (QAAFI) could help slow eye diseases such as age-related macular degeneration (AMD), the leading form of blindness in Australia.

Fields of gold for better vision

The Queensland Department of Agriculture and Fisheries (DAF) leads a research project with QAAFI to breed higher levels of zeaxanthin in sweet corn. Zeaxanthin is thought to be associated with a reduced incidence of Advanced Macular Degeneration, which often results in vision loss.
