Research interests/background

Phosphorus (P) is a fundamentally essential nutrient for plant growth which cannot be synthesised unlike Nitrogen. Moreover the sole resource of P fertiliser, rock phosphate is getting depleted. Given the P scarcity and sustainability, it is important to use P more efficiently. Therefore, I am interested in recycling P within the plant, especially major cereal crop, rice (Oryza sativa L.). My PhD research project is aiming for understanding molecular regulation of P remobilisation during grain filling in rice. Ultimately, we would like to reduce the amount of P loading into grain which may impact on improving metabolically active P in vegetative tissue which results in enhancing energy metabolic process photosynthesis, thus grain yield as well as reducing P waste at grain harvest.

In order to achieve this goal, we need to understand the physiology mechanism and molecular regulation involved in P remobilisation during grain filling stage.

I am under taken this project supervised by Dr. Terry Rose and Dr. Daniel Waters at Southern Cross Plant Science and external supervisor Dr. Sigrid Heuer from Australian Centre for Plant Functional Genomics (ACPFG) in Adelaide.
