Nonhebel, Heather - University of New England - School of Science and Technology

个人简介

I have BSc (Hons) and PhD degrees from the University of Glasgow, Scotland. I have worked as a Research fellow at Michigan State and New South Wales Universities. I also held lecturing positions in Biochemistry at the Universities of Auckland and Western Sydney before coming to UNE.

研究领域

Research Interests My research is focussed on understanding signalling that directs photosynthate into developing cereal grains where it is deposited as starch. In particular I am researching the roles of plant hormones auxin or indole-3-acetic acid and abscisic acid in this process and their connection with sugar signalling and the activity of the cell wall, sucrose degrading enzyme, invertase. The signalling that occurs during early grain fill is highly sensitive to temperature stress, leading to poor grain fill and low quality chalky grains. We are investigating the response of signalling genes to heat stress with a view to developing molecular markers that may assist in developing heat tolerant varieties. Most work is done with rice, however we have recently also started to work with sorghum.
