| Research Activities |
The research program is an integral component of
the ARC Centre of Excellence in Plant Energy Biology, which is based at ANU,
UWA and USyd. The Centre offers Honours scholarships ($6K) and topup scholarships for PhD
students ($7K), in addition to well funded research, conference travel and
graduate training programs. See http://www.plantenergy.uwa.edu.au/ for more details.
Signalling between organelles and between sun and shade leaves:
1. We are studying the mechanisms by which plants perceive and respond to drought and excess light. This requires signals from the chloroplast to the nucleus, a process known as retrograde signaling.
2. During chloroplast biogenesis novel genes control the rate of development of the chloroplast. This is being studied using snowy cotyledon mutants (sco).
|
3. A leaf exposed to full sunlight will transmit a signal to shaded leaves enable a systemic acquired acclimation (SAA) response. The nature and regulation of SAA is under investigation.

Functional Genomics of Environmental Stress: We are studying the mechanism of drought stress signaling in Arabidopsis and crop plants using mutants that are most resistant to drought.
The approach utilizes cutting-edge genomic technologies, such as DNA chip arrays and high throughput screening of promoter-reporter gene fusions to identify novel genes and signalling pathways in the model plant, Arabidopsis, wheat, rice and the alga, Chlamydomonas.
We are incorporating this knowledge into the development of drought tolerant crops. |
Photosynthesis and photoprotection : Antixoidants, such as carotenoids are essential for the survival of plants. We are determining their roles as safety valves against oxidative damage induced during photosynthesis. This program is a combination of biochemical genetics and physiology. Work uses Arabidopsis, CHlamydomonas and avocado |

Regulation of Carotenoid Biosynthesis: Our work is focused on the characterization of plant pigments, particularly carotenoids and their role in photosynthesis and chloroplast development. Carotenoids are important pigments in photosystems, many fruits, flowers, and seafood. Nutritionally they are the source of vitamin A and offer some protection against certain cancers, heart and eye diseases. Thus, understanding their biosynthesis may lead to improved nutritional value of foods. The goals are to elucidate the mechanisms that control carotenoid accumulation using biochemical genetics.
Plant Development, Auxin and Carotenoid Biosynthesis. A recently identified novel gene alters the number of branches on a plant and the carotenoid content of the cell. The project is to study the function and subcellular distribution of this gene and determine its role in apical dominance, developmental biology and carotenoid biosynthesis. |
Collaborative projects: Several projects are undertaken by students based in CSIRO. For example, there is a project relating to cereal colour and nutritional content of wheat with Dr Howitt and Dr Morell. |
