MicroRNA control of gene expression and development in plants. Controlling a gene's activity is fundamental in biotechnology, from dissecting a gene's function to introducing desired traits in crop plants. Recently a new class of genes have been identified that are 'master-regulators' able to control the activity of many genes, and through this, they can ultimately control how an organism develops and functions. By understanding how these genes operate and the extent of their influence, not only ....MicroRNA control of gene expression and development in plants. Controlling a gene's activity is fundamental in biotechnology, from dissecting a gene's function to introducing desired traits in crop plants. Recently a new class of genes have been identified that are 'master-regulators' able to control the activity of many genes, and through this, they can ultimately control how an organism develops and functions. By understanding how these genes operate and the extent of their influence, not only will we gain greater insights into the gene regulatory networks required for multicellular life, but how we may develop methods of controlling gene activity that will have tremendous biotechnological applications.Read moreRead less

Plant microRNA targeting: defining regulatory factors additional to complementarity. Central to our understanding of microRNA biology is the identification of which genes they target. In plants, high complementarity is regarded as the sole determinant, and drives bioinformatic predictions. However, functional evidence is inconsistent with this, arguing that complementarity alone is insufficient to accurately predict targets. This project uses novel applications of next generation sequencing to c ....Plant microRNA targeting: defining regulatory factors additional to complementarity. Central to our understanding of microRNA biology is the identification of which genes they target. In plants, high complementarity is regarded as the sole determinant, and drives bioinformatic predictions. However, functional evidence is inconsistent with this, arguing that complementarity alone is insufficient to accurately predict targets. This project uses novel applications of next generation sequencing to categorise bioinformatically predicted Arabidopsis targets as either strongly or poorly regulated. These categories will be analysed to determine what factors, in addition to complementarity, are required for strong targeting. The outcomes will impact artificial microRNA design and have important implications for biotechnology. Read moreRead less
Australian plague locust population genetics and migratory behaviour. The project will allow improved monitoring and forecasting of locusts in Australia and thereby help prevent locust outbreaks. Benefits will arise directly through greater effectiveness in reducing locust damage to crops, and indirectly to Australian rural industry generally through the economic benefits of reduced losses and locust control costs. Environmental and social benefits will also arise from reduced, better targeted u ....Australian plague locust population genetics and migratory behaviour. The project will allow improved monitoring and forecasting of locusts in Australia and thereby help prevent locust outbreaks. Benefits will arise directly through greater effectiveness in reducing locust damage to crops, and indirectly to Australian rural industry generally through the economic benefits of reduced losses and locust control costs. Environmental and social benefits will also arise from reduced, better targeted use of chemical insecticides. This in turn can produce secondary economic benefits, e.g. through enhanced growth and profitability of the organic beef industry within the main locust-outbreak area. Read moreRead less
TraitCapture: Genomic modelling for plant phenomics under environmental stress. This project aims to develop software to integrate new hyper-spectral and 3D growth models of plant phenomics with population genomics to identify heritable developmental traits across varied environments. Genome wide association studies aim to then be used to identify causal genes. Functional structural plant models incorporating genetic variation will be used to predict growth under simulated stress environments. ....TraitCapture: Genomic modelling for plant phenomics under environmental stress.

Genome wide association studies aim to then be used to identify causal genes. Functional structural plant models incorporating genetic variation will be used to predict growth under simulated stress environments. The research team unites international industry, the Australian Plant Phenomics Facility, and university statistical geneticists. TraitCapture software will use open standards applicable to both controlled and field environments enabling plant breeders to pre-select adaptive traits to increase crop productivity under environmental stress.Read moreRead less

The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentially provide new opportunities and platforms for improving the performance, yield and quality of crop plants. The proposed study is therefore consistent with the national research priority goals such as breakthrough science, frontier technologies and promoting an innovation culture.Read moreRead less
Controlling the rate of transcription and translation of Rubisco transgenes effectively in higher-plant plastids. Genetic transformation of the circular genome of the plastids provides a containable means for modifying plant growth by manipulating photosynthesis. Although the transformation mechanism is precise, predicting the level of foreign gene expression is difficult because the amounts of messenger RNA and protein produced by foreign genes in plastids varies widely, even when the protein a ....Controlling the rate of transcription and translation of Rubisco transgenes effectively in higher-plant plastids. Genetic transformation of the circular genome of the plastids provides a containable means for modifying plant growth by manipulating photosynthesis. Although the transformation mechanism is precise, predicting the level of foreign gene expression is difficult because the amounts of messenger RNA and protein produced by foreign genes in plastids varies widely, even when the protein assembles without difficulty. This project will devise strategies for controlling this variability that will facilitate attempts to exploit plastid transformation for transplanting better versions of the photosynthetic CO2-fixing enzyme, Rubisco, into plants to improve their growth efficiency in terms of water, fertiliser and light use.Read moreRead less

This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii. Comprehensive profiles of transcriptome-proteome linkage will be constructed without the complications of multicellularity for this unicellular photosynthetic model organism. We will establish a public proteome reference database and provide new microarrays and molecular markers beneficial for research in Chlamydomonas. We expect to advance understanding of high light resistance mechanisms so that it will eventually be applicable to improve productivity in crop plants growing under various environmental stress conditions.Read moreRead less
