Waite Agriculture, Food and Wine Seminar Series

Apr 4, 10:30 am - 11:00 am

Please come along to this campus-wide seminar series. One week we will hear from a group leader or a visitor to the campus and the following week from ECR/MCRs from the Waite Future Leaders cohort. Come and hear about great science going on across the campus, up the road or across the sea! Expand your network and find new collaborators!

Everyone is welcome to a shared morning tea (please bring your own coffee cup) following the seminar.

WHEN: Thursday 4th April. 10:30am Seminar, 11:00am morning tea
WHERE: Plant Research Centre Auditorium
SPEAKER:  Dr Penny Tricker, Wheat Hub | school of Agriculture, Food and Wine
Novel traits and alleles for drought and heat stress tolerance in wheat


Drought and heat stress episodes are increasing in frequency and severity causing significant crop yield losses. Despite this, these stresses have rarely been studied together in wheat, but their combined effect is known to differ from the effect of each stress singly. In our programme in the ARC ITR Hub for Wheat in a Hot and Dry Climate, we use genetic diversity of wheat to explore the physiology of tolerance to combined drought and heat stress during grain filling and to associate phenotypic traits with genetic markers. We have explored whole plant water use and response to vapour pressure deficit, spike hydraulics and water potential gradients, isolation of spike tissues and the partitioning of water soluble carbohydrates following drought and heat stress as physiological traits for tolerance. The effects of drought and heat cannot be controlled in rainfed wheat and new, more tolerant varieties are required to mitigate adverse effects on productivity. We also found new quantitative trait loci associated with yield component traits and incorporated beneficial, exotic alleles into novel germplasm that can be used in breeding for drought and heat tolerant wheat.

About the Speaker

Penny Tricker is a Senior Lecturer in the Genetics and Genomics Group and Research Fellow with the Wheat Hub and School of Ag, Food and Wine. She completed her PhD in Plant Biology at the University of Southampton (UK) and gained postdoctoral experience with Rothamsted Research and the University of Reading. At the end of 2011, Penny moved to the University of Adelaide and, subsequently, the Australian Centre for Plant Functional Genomics. Her research uses both forward and reverse genetic approaches to improve the tolerance of wheat, barley and grapevine to abiotic stresses including drought and heat. Penny has a particular responsibility for durum wheat research and leads a collaboration with the Crop Development Centre of the University of Saskatchewan and the Dept. of Agriculture of the University of Tuscia. She continues to research the role of the epigenome in plant biology, including evolutionary and population genetics and, functionally, its potential for crop improvement and its role in priming for stress tolerance.
