Harnessing horizontal gene transfer for sustainable nitrogen fixation. This project aims to investigate natural deoxyribonucleic acid (DNA) transfer from nitrogen-fixing bacteria to indigenous bacteria in Australian soils. This project expects to significantly expand our understanding of the molecular and genetic factors contributing to the evolution of ineffective symbiotic bacteria in these soils. An expected outcome of this project is support development of genetically stable bacterial inocul ....Harnessing horizontal gene transfer for sustainable nitrogen fixation. This project aims to investigate natural deoxyribonucleic acid (DNA) transfer from nitrogen-fixing bacteria to indigenous bacteria in Australian soils. This project expects to significantly expand our understanding of the molecular and genetic factors contributing to the evolution of ineffective symbiotic bacteria in these soils. An expected outcome of this project is support development of genetically stable bacterial inoculants for use in agriculture. Inoculation of legumes with nitrogen-fixing symbiotic bacteria is a cheap and environmentally-friendly alternative to chemical fertilisers and contributes $3-4 billion per annum to Australian economy.Read moreRead less
Turning sand into sheep feed - Lebeckia ambigua an agricultural perennial! This project aims to develop nitrogen-fixing legumes adapted to the changing climate. Nitrogen fixation from legumes is worth $3 billion to the Australian agricultural economy, but changing rainfall patterns threaten much of this. One solution is to transition pasture growth to a reliance on perennial plants, which are less affected by unseasonal rain. Lebeckia ambigua is an outstanding perennial legume to begin this chan ....Turning sand into sheep feed - Lebeckia ambigua an agricultural perennial! This project aims to develop nitrogen-fixing legumes adapted to the changing climate. Nitrogen fixation from legumes is worth $3 billion to the Australian agricultural economy, but changing rainfall patterns threaten much of this. One solution is to transition pasture growth to a reliance on perennial plants, which are less affected by unseasonal rain. Lebeckia ambigua is an outstanding perennial legume to begin this change, but its nitrogen fixation is compromised by nodulation failure caused by death of its symbiotic rhizobia. This project intends to improve the survival in acid and infertile soils of the unique rhizobial symbionts the research team has discovered for Lebeckia ambigua in South Africa.Read moreRead less
