Abstract
Modification of assimilate partitioning in crops has applications in maximising carbon and nitrogen resource use efficiency and allocation of these resources to harvested products. Further applications are improved adaptability of crops to environmental change. Earlier results on transgenic plants with altered primary carbon metabolism and effects of environment on metabolism emphasised the fundamental regulation at the molecular level by carbon and nitrogen signals arising from metabolism. The project seeks to understand the feedback mechanisms that operate between metabolism and gene expression, and the integration of expression of genes that determine assimilate partitioning and resource allocation in plants. The approach is that of understanding the interface between metabolism, sugar sensing and resource allocation, basically source/ sink interactions, their control and signalling mechanisms. Specific objectives are the role of trehalose metabolism in the interface between sugar signalling and resource allocation, and that of SnRK1, a protein kinase related to yeast SNF1 (sucrose non-fermenting-1). A long-term goal is to identify molecular mechanisms that link carbon status with resource allocation.
