Abstract

The synthesis of kestoses (trisaccharides composed of two fructose units and one glucose unit) by races 0 and 1 of Phytophthora parasitica var. nicotianae is shown. The trisaccharide is found in culture filtrates of isolates grown in liquid media containing 3% sucrose. The utilization of sucrose and trisaccharide formation by the organisms over a 16-day period is described. The kestoses were identified by chemical and enzymatic analysis, and two of three possible isomers were found.
