Overview

Dr Jaquie Mitchell has a research focus on improving the physiological understanding of abiotic stress resistance in various crop species. She has been working at the University of Queensland in the School of Agriculture and Food Sciences since 1990. As a crop physiologist Jaquie has been working on various projects examining genetic variation for resistance to abiotic stress, such as low-temperature tolerance at the reproductive stage in rice, the advantage of reduced-tillering gene in wheat grown under terminal drought, the effect of salinity and water-deficit on production of volatile compounds in aromatic rice. Jaquie has also been working as an agronomist in rice and cropping systems (non-rice crops in dry-season eg. Mungbean, peanut, maize) research in the Mekong region (Laos, Cambodia and Thailand) for over 20 years largely through ACIAR and Generation Challenge Program funding. Jaquie provides specialist guidance and assistance to undergraduate and postgraduate research students within crop physiology and agronomy. She has extensive experience conducting research projects focused on abiotic stress resistance in various crop species, and cropping systems research in the Mekong region of south east Asia.

Research Interests

  • Cropping intensification & diversification in SE Asia
    Our current ACIAR project in SE Asia (2014-19) is focused on mechanization and value adding for diversification of lowland cropping systems in Lao PDR and Cambodia. Also have a focus on improved agronomic management in lowland rice-based cropping systems in Laos and Cambodia, focussing on adding non-rice crops such as maize, peanuts, soybean and mungbean to predominantly rice based cropping systems.
  • Physiological traits of importance for rice production under aerobic conditions
    Aerobic rice in southern Australia is a potential new system, and as such little research has been conducted on the identification of donor varieties with specific adaptation to aerobic conditions, nor the physiological mechanisms underlying the requirements for aerobic varieties.This project aims to develop screening methods to identify donor varieties and evaluate genetic variation in key traits that contribute to aerobic adaptation. The project will link phenotype to genotype and identified traits to genomic regions for the direct incorporation into the Australian rice breeding program to maximize productivity of rice adapted to a new reduced water input system.
  • Cold tolerance in rice
    A RIRDC funded rice project 'Cold tolerant traits and QTLs for improved efficiency of rice breeding program' has commenced in late 2012 where we examine low temperature tolerance in rice, mostly targeting the NSW rice industry. The major objective of the project is to improve understanding of cold tolerance in terms of underlying physiological mechanisms and the molecular basis (genomics) of traits involved in the maintenance of cold tolerance.
