Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones bu ....Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones but directly influencing how well critical genes work. Their exploitation holds great promise for manipulating plant performance and enhancing crop yields. Read moreRead less

Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide ....Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide a model to assess the more general occurrence of dual-targeted proteins in plants. The aim is to identify and eventually exploit the signalling mechanism(s) that mediate communication between plastids and mitochondria.Read moreRead less
