A molecular-genetic approach to studying source-sink interactions in Arabidopsis thaliana. Final report, April 1, 1995--March 31, 1998
The ultimate goal of this research is to elucidate the molecular mechanisms by which the complex interactions between sources and sinks of fixed carbon are controlled in plants. As soluble sugar levels have been shown to play a vital role in a variety of source-sink interactions, a key aspect of the authors research is to determine the role of sugar-regulated gene expression in mediating source-sink interactions. In addition, as a critical aspect of source-sink interactions is the channeling of fixed carbon into different storage forms, they have pursued the findings that fumaric acid represents a significant form of storage carbon in Arabidopsis thaliana and other plant species. In the future, a better understanding of the mechanisms by which interactions between sources and sinks of fixed carbon are coordinated will be a pre-requisite to developing more rationale approaches to improving harvest indices in crop species.
