Transformation von α-Tomatin durch Botrytis cinerea

Abstract

Botrytis cinerea Pers. has been shown to be capable of enzymatically transforming α-tomatine incubated in nutrient medium and naturally occurring in leaves of tomato plants. Thereby two transformation products are formed on different metabolic pathways: 1. By extracellular, constitutive fungal enzymes tomatine is converted to a hitherto unknown, less polar compound which still contains the four sugar units (xylose, 2 glucose, galactose). 2. Also by extracellular, but inducible enzymes which split off the whole tetrasaccharide as one unit, the aglycone tomatidine is produced.
