Rice

Research Summary

Rice is a key crop in the world food system supplying the major source of human dietary energy for half the human population. Worldwide rice consumption is increasing at 2% a year, presenting significant challenges to the rice research community.Southern Cross Plant Science has participated in rice research which has elucidated the link between gene sequence and rice grain quality, examined the physiology and genetics of nutrient utilisation efficiency and tolerance to abiotic stresses, identified patterns of genome variation across cultivated rice and characterised wild rice resources.

Current research interests include:

  • Rice grain quality
  • Rice phosphorus metabolism
  • Australian wild rice genome and trait characterisation
  • Molecular marker discovery for rice breeding
  • Iron toxicity tolerance in rice
  • Abiotic nutrient stress tolerance in rice

Funding/Collaborators

  • ARC
  • RIRDC
  • Global Rice science Partnership (GRiSP)
  • Prof. Robert Henry, University of Queensland
  • Dr Matthias Wissuwa, Japan international Research Center for Agricultural Science
  • Dr Russell Reinke, International Rice Research Institute
  • Dr Peter Snell and Dr Rachelle Ward, Yanco Agicultural Institute.

Research outcomes

  • Identification of the major gene for fragrance in rice
  • Genetic control of rice starch properties
  • Resolution of Australian wild rice taxonomy
  • Insight into genetic and physiological mechanisms of plant phosphorus use efficiency
