PAP signals a survival advantage during water deficit in Arabidopsis plants During 2010 I have continued working towards my PhD, researching the molecular and biochemical mechanisms plants use to adapt to low water availability and drought... In our research group we have been studying a subtle mutation in Arabidopsis (a close relative of Canola) that may have important implications for drought resistance in many crops... The focus of my research is to determine if and how this chemical assists plants to adapt to water deficit or confer drought tolerance...

The project aimed to isolate and understand the interplay of genes specifically involved in the regulation of resistance so that the molecular basis of the plant-pathogen interaction (between barley and Rhynchosporium secalis and Pyrenophora teres ) can be understood as a basis for improving disease resistance... In the project, the University of Adelaide focused on candidate genes involved in changes to the cytoskeleton, oxidative signalling, repair of oxidative damage, inhibition of fungal toxins and antioxidant capacity... Results from the project suggest a promising approach for the establishment of durable and broader resistance to a suite of evolving plant pathogens through the use of well-characterised regulatory genes and specific promoters...

Frost is a severe dehydrative stress and a significant problem for Australian agriculture, causing annual yield losses estimated at $33 million in South Australia and Victoria... Dehydrins are a group of plant proteins involved in tolerance to cold and drought stress... Some of the genes code for proteins that can act as master-switches which turn on other genes and regulate plant development and metabolism...

The objective of the project was to explore methods to integrate new marker technologies, simulation modelling and statistics with the aim of increasing the rate of genetic gain in breeding programs focused on complex traits such as grain yield... To the end the main areas of research were 1) developing the capacity to detect quantitative trait loci (QTL) in breeding populations and 2) using simulation modelling to enhance plant breeders' understanding of complex traits and genotype x environment (GxE)... The objective of the project was to explore ways of helping crop improvement programs use new technologies to improve progress for complex traits...

Part of the project aims to characterise, assess, and simulate the suitability of current genetics for earlier sowing in Australian farming systems across a range of environments using crop management tools such as APSIM... The PhD project aims to identify how molecular changes within the mitochondria allow plants to continue growth at a range of temperatures... Education and research are critical in developing the 'science push' for sorghum as a health promoting food - this knowledge needs to be interpreted and disseminated to the Australian grains industry (farmers, producers), food products developers, marketers and key government organisations y t i c a p a C & s l l i k S g n i d l i u B ...

A gene activation screen to identify genes that can induce rust resistance... The outputs of the project represent major stepping stones within the long term vision to rust proof Australian wheat crops through conventional pyramiding of rust resistance genes made more efficient using molecular markers and using GM wheat with insertion cassettes of multiple cloned or synthetic rust resistance genes... The system is also applicable to other characters of interest including abiotic stress...

Molecular genetic markers obtained from the proprietary EST resource, as well as those in the public domain, were mapped in reference mapping families from B. napus as well as the progenitor species Brassica rapa and Brassica oleracea , and in six trait-specific mapping families... Candidate gene identification and characterisation for enhanced oil quality, drought tolerance, shattering resistance and other identified traits was also performed using GS-FLX...
