Summary
Processes of plant growth that impact agriculture and horticulture. The project aims to discover the genes and processes that control plant shoot architecture, which is a major driver of yield in field, horticultural and forestry crops. Shoot branching is the result of the complex interplay of genes, environment and crop management. By investigating cellular processes governing growth and development, as well as physiology and molecular genetics, this project will enhance Australian capacity and ....Processes of plant growth that impact agriculture and horticulture. The project aims to discover the genes and processes that control plant shoot architecture, which is a major driver of yield in field, horticultural and forestry crops. Shoot branching is the result of the complex interplay of genes, environment and crop management. By investigating cellular processes governing growth and development, as well as physiology and molecular genetics, this project will enhance Australian capacity and multidisciplinary innovation. An improved understanding of shoot branching and how it may be manipulated will improve our knowledge of plant sciences that could contribute to agricultural expansion and food security in Australia and internationally.Read moreRead less
Strigolactone, a new plant hormone: its regulation, role and potential for plant improvement. This Project will investigate a new plant hormone, one of only 10 or so discovered to date in plants. This hormone regulates shoot number, water and nutrient uptake and the ability of shoots to generate roots and develop wood. The Project will produce genetic tools and describe new processes for applications in sustainable plant improvement.
The tree legume Pongamia pinnata on coal mine spoil: an integrated and sustainable rehabilitation, bioenergy and carbon farming production system. This project aims to assess the growth performance of the tree legume Pongamia pinnata on coal mine overburden. The expected growth of Pongamia on what is regarded as poor quality soil will lead to the development of an integrated production system that will provide benefits through rehabilitation of lands, biofuel feedstock, and carbon farming.
How do sunflowers make protein drugs in their seeds? We recently discovered in sunflower the origin of a small protein ring that chemists have used for a decade to base designed drugs upon. This project aims to know how sunflowers make it so we may manipulate other plants to manufacture ring-based drugs.
The new plant hormone controlling shoot branching. This project will create genetic tools and knowledge on the control of a new plant growth hormone that affects a diverse number of plant properties. These important traits include shoot number, water and nutrient uptake, wood production, the ability to generate roots and the ability to stimulate particular potentially devastating parasitic weeds.
A new and rapidly evolving class of plant peptides. The project will study a diverse class of drug-like mini-proteins that are thought to have emerged genetically over 12 million years ago. This project will explore why plants have kept making these mini-proteins for so long and whether it is the same reason the founding member of this mini-protein class is such a good drug.
Fertility crisis: harnessing the genomic tension behind pollen fertility in sorghum. Hybrid sorghum varieties yield more grain than inbred varieties but the production seed for farmers can be difficult. This project will identify the genes responsible for a trait that makes hybrid seed production possible and this knowledge will help raise sorghum yields in Australian and in some of the world’s poorest countries.
Functional analysis of alternative splicing in plants. Higher temperatures affect flowering and seed set in plants. How plants sense and respond to temperature is currently unclear. Here we study alternative splicing, one of the processes affected by temperature. These studies will advance our knowledge and help develop crops that can withstand negative effects of climate change.
The Role of Sugar Demand in Apical Dominance: Branching in a New Direction. For centuries, people around the world have made use of the knowledge that pruning the growing tips of shoots causes buds on the stem below to grow out into branches. Yields in crop, horticulture and forestry industries depend on shoot architecture. Since the discovery of auxin in the 1930s, shoot branching has been thought to be regulated by plant hormones. However, in this project we propose a new theory whereby shoot ....The Role of Sugar Demand in Apical Dominance: Branching in a New Direction. For centuries, people around the world have made use of the knowledge that pruning the growing tips of shoots causes buds on the stem below to grow out into branches. Yields in crop, horticulture and forestry industries depend on shoot architecture. Since the discovery of auxin in the 1930s, shoot branching has been thought to be regulated by plant hormones. However, in this project we propose a new theory whereby shoot tip demand for sugar is predominant in apical dominance; enhanced sucrose, a mobile sugar, is necessary and sufficient for the initial growth of buds. This project aims to expand this theory, revealing underlying components involved in sucrose action and describe how the network of sugar demand and hormones acts to control shoot architecture.Read moreRead less
New plant development discoveries stem from strigolactone research. This project involves a new plant hormone, strigolactone, and the way it controls wood and root formation in above-ground parts of plants. It will identify new plant genes involved in these processes and provide greater understanding of how plant hormones interact to control these important traits.
