Abstract 

 Environmental effects on flavour development in Australian varieties of strawberry

The Australian strawberry industry has raised concerns of a public perception that strawberries are not what they used to be in terms of their flavour. In recent years, local varieties have been produced, whose flavour characteristics have been rated as superior to imported varieties. As the aroma and flavour of strawberries are significantly affected by environmental factors, research is required to determine the optimal growing conditions for these new varieties. Further, as the final flavour characteristics of a variety depends on the interaction between the genes it carries and the environment, the current project also attempts to elucidate the relative importance of the genotype versus the environment. To date, correlations have been established between the chemical profiles derived from GCxGC and GC-TOFMS in ripe strawberries and also between gene expression profiles in unripe fruit with the variations in several key environmental parameters during the growing season. There is also evidence from our studies that despite the significant influence of the environment, flavour development is highly heritable. The findings from this research may therefore assist in the development of DNA marker-assisted breeding for the genes controlling various aspects of flavour development in strawberries.

  

Biography  

 

Qualifications

PhD, University of Melbourne, 1992

Bachelor of Agricultural Science (Honours), University of Melbourne, 1988

Summary of responsibilities

 

  • Undergraduate teaching in plant science, genetics and molecular biology
  • Postgraduate teaching in molecular genetics, tissue culture and Chinese medicinal botany
  • Supervision of Masters and PhD students
  • Member of a number of University committees

Research Interests

My main research focus is on the use of molecular (DNA/RNA) methodologies for accelerating the production of new plant varieties for agriculture. My research team is currently using DNA microarrays, genome maps and PCR-based diagnostics to detect and map genes responsible for resistance to biotic and abiotic stresses in chickpea and vegetable Brassicas.Further, we are investigating quality aspects of food and medicinal plants using molecular tools, for example, the detection of the genes responsible for flavour development in strawberry (using microarrays) and the validation of the identity of Chinese medicinal herbs for quality assurance purposes.

I am a member of the Health Innovation Institute within RMIT, and a steering committee member for the establishment of a Chinese herbal farming industry in the City of Whittlesea.

I have successfully supervised over 10 PhD students, as well as 2 Masters by Research and 10 Honours students.

Research Areas

  • Biotic and Abiotic Stress in Crop Legumes
  • Flavour Development in Strawberry
  • DNA Fingerprinting of Western and Chinese Medicinal Herbs

Specialty Expertise Areas

  • Plant Breeding
  • Marker-assisted Breeding
  • Genome Mapping
  • Genomics
  • Microarray-based DNA Fingerprinting

Research Accomplishments

I have been awarded grants in excess of $1.5 million (cumulatively) by the ARC (Linkage scheme), Grains Research and Development Corporation (GRDC), Horticulture Australia (HAL), and the Rural Industries Research Development Corporation (RIRDC). I have active collaborations with The City of Whittlesea, The Victorian Strawberry Growers Association, Hendersons Seeds, Mediherb, Botanical Resources Australia, and The University of Melbourne.

Teaching Activities

I am responsible for undergraduate teaching in plant science, genetics and molecular agriculture, and postgraduate teaching in molecular genetics, tissue culture and Chinese medicinal botany. I currently coordinate courses in cell and tissue culture and molecular agriculture.

Teaching Accomplishments

My main teaching innovations include:

The internationalization of our environmental conservation teaching, by partnering with The International Student Volunteers, Inc. to offer work-experience in conservation in a number of countries, including Costa Rica and Thailand.

The establishment of a teaching and research garden for Chinese Medicinal Botany on the Bundoora campus. This garden provides flexible learning opportunities through the use of a “museum-style” self-guided tour employing audio commentaries of each plant species.

  • City of Whittlesea Steering Committee for Chinese Herbal Farming
  • Frequent reviewer for a number of Australian, and international journals
  • Frequent examiner of PhD and Masters theses
