Abstract
Carbohydrate deprivation of cells or tissues is common in plants. Other carbon sources may then be employed for respiration or biosynthesis. Glyoxylate cycle enzymes are synthesised in response to carbohydrate deprivation, but their function is unknown. The cycle could have respiratory, anapleurotic or gluconeogenic roles, with importance in resource allocation in growing plants and harvested products. The aims are (1) to determine if the cycle provides mechanism to adapt to and survive carbohydrate deprivation, and (2) to elucidate the metabolic role of the cycle during carbohydrate deprivation. Arabidopsis insertion mutants for glyoxylate cycle enzymes will be isolated, mutant phenotypes analysed, and specific radioactive substrates used to trace glyoxylate cycle products.
