Abstract
The ISI1 gene was identified in a screen for reduced gene expression in response to sucrose. The expression pattern of ISI1, the phenotypes caused by over-expression of ISI1 in phloem companion cells of source leaves, and biochemical analysis of isi1 lines, all suggest ISI1 is a phloem- localised regulator of sugar responses. The objective of this work is to define the function of the ISI1 gene using a physiological, biochemical and genetic strategies. We will also define other components of the isi1 signalling pathway in a genetic screen. The work will lead to better understanding of sugar-mediated signalling, phloem function and resource allocation in plants.
