Abstract

The discovery of the trehalose pathway as a central and indispensable regulatory system in plants is a major finding in the study of metabolic regulation in recent years. Research on transgenic and mutant plants has shown that there is an obligate requirement for the trehalose pathway and the metabolite trehalose 6-phosphate (T6P), in particular for carbohydrate utilisation. An important consequence of altered T6P-dependent metabolism in leaves is an impact on photosynthesis: transgenic plants with elevated T6P content show a large increase in photosynthetic capacity per unit leaf area. Furthermore, modification of T6P content causes predictable changes in carbohydrate and photosynthetic metabolism and in leaf development showing that these three processes are linked through T6P. New data show crosstalk between T6P and SnRK1. the proposal seeks to investigate this crucial role of T6P in integrating leaf physiology using transgenic and mutant Arabidopsis with perturbed T6P metabolism and perturbed SnRK1 activity focusing on: 1) The molecular and biochemical base of T6P-dependent changes in metabolism and leaf development; 2) regulation of T6P metabolism by native Arabidopsis genes and their role in the integration of leaf physiology.
