Abstract
Sugars play an important role in the regulation of plant metabolism and development. To identify the signalling function of sugars during leaf senescence, the sugar-dependent expression of senescence-associated genes will be analysed in wild-type Arabidopsis and in a sugar-insensitive mutant. Analysis of photosynthesis and of resource allocation will reveal the importance of sugar-regulated senescence for plant growth. Fluorescence imaging will be used to isolate new mutants affected in the sugar-mediated initiation of senescence in order to extend our knowledge of the role of sugar signalling in the degradation of the photosynthetic apparatus. The results will allow the development of the model of the regulation of senescence by sugars.
