Abstract
During parasitic development of Claviceps purpurea (Fr.) Tul. on rye the initial sporulating sphacelial mycelium had an endogenous respiration consistent with oxidation of carbohydrate. Exogenously supplied sugars were fermented. Differentiation to the plectenchymatic sclerotial growth form was accompanied by a large decrease in endogenous respiration and in the ability to utilize exogenously supplied sugars. However, the greatest fermentative capacity of all tissues was found in actively growing sclerotial mycelia. With increasing age sclerotial tissues resorted to oxidation of lipid. Sphacelial and sclerotial tissues grown in axenic culture did not exhibit these distinctive capacities for carbohydrate utilization. It is concluded that the marked changes during parasitism can be ascribed primarily to the morphological and organisational differences between the two types of tissue.
