Evolution of diverse symbiotic phenotypes among native soil bacteria following spread of a genomic island from a rhizobial inoculant. The quality of legume protein depends on symbiotic nitrogen fixation by root nodule bacteria (RNB). Sustainable legume production in Australian agriculture depends on legume inoculation with effective strains of these bacteria.

The quality of legume protein depends on symbiotic nitrogen fixation by root nodule bacteria (RNB). Sustainable legume production in Australian agriculture depends on legume inoculation with effective strains of these bacteria. Unfortunately inoculant strains transfer DNA to other soil bacteria resulting in soil populations of RNB that compete for nodulation but are less effective in nitrogen fixation. This transfer of DNA threatens a $2 billion asset in Australian agriculture. We will use molecular microbial ecology to investigate the mechanisms of genetic transfer of symbiotic DNA in RNB, and use this knowledge to prevent it.Read moreRead less

Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental ....Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental risk assessment framework as a basis for (i) educated decisions regarding land development and soil disturbance vs conservation as well as (ii) identifying areas suitable for water abstraction from groundwater resources. This will ensure sustainable use of precious groundwater resources in this drying continent of ours.Read moreRead less

It can evaluate trade-offs between sustainability strategies, integrating research and outcomes, making them accessible to managers. It will build a coordinated research capability that directly supports Australia's goal of ecologically sustainable development. Read moreRead less
Ecosystem response to climate and anthropogenic disturbances: implications for greenhouse gas emissions and nutrient cycling. Humanity is challenged with climate change, greenhouse gas emissions, declining fertiliser reserves and a need to feed the world's growing population. This project will result in greater understanding of how ecosystems can respond to these challenges and provide a framework to help Australia manage its agricultural and natural reserves.
Co-variant analysis and statistical modelling for improved crop yield. This project plans to develop mathematical tools that will help to identify cereal plant varieties with the highest yield. This is a critical responsibility of plant breeders and many Australian breeders acquire and store important information related to the issue. However, there are as yet no mathematical tools that are able to co-analyse the heterogeneous and high-dimensional data in order to understand how external and int ....Co-variant analysis and statistical modelling for improved crop yield. This project plans to develop mathematical tools that will help to identify cereal plant varieties with the highest yield. This is a critical responsibility of plant breeders and many Australian breeders acquire and store important information related to the issue. However, there are as yet no mathematical tools that are able to co-analyse the heterogeneous and high-dimensional data in order to understand how external and internal factors correlate with the major growth and development stages at the crop level. This project seeks to develop and implement mathematical and statistical tools to analyse genetic, agronomic and phenomic factors that affect plant performance, to deliver advanced yield prediction.Read moreRead less

Subterranean clover is the most widely sown annual pasture legume species in southern Australia. It is native to the Mediterranean basin and has been sown over an estimated area of 22 million hectares. This project will provide breeders with a genomic resource for future breeding programs focused on methane emission mitigation and ruminant health. The focused marker assisted breeding will lead to more efficient and effective breeding of elite cultivars for sustainable and profitable farming systems to benefit the wool and meat industries. Low methanogenic pastures with low isoflavone content offer an exciting avenue for agriculture to reduce its carbon footprint whilst maintaining or improving profitability.Read moreRead less
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
The Betaproteobacteria: could they play a key role in nitrogen fixation on infertile soils with legumes adapted to climate change? Microbial biosecurity is often overlooked when introducing agricultural species to Australia.

Microbial biosecurity is often overlooked when introducing agricultural species to Australia. As we research new legume species to make our $44 billion agricultural industries robust in the face of a changing climate, we need to be aware of the implications of the associated introduction of (beneficial) microbes. By exploring the globe for plants from regions that already have the climate we are transitioning towards, we have discovered new perennial forage legumes from which we can build a robust agriculture in the arid regions of southern Australia. This will have enormous national benefit in rural regions. This project will research the essential microbial inoculants associated with these new plants.Read moreRead less
