Abstract
Sucrose, glucose, and inositol were the major sugars in cabbage hypocotyls infected by Plasmodiophora brassicae and in noninfected hypocotyls, based on paper, thin-layer, and gas-liquid chromatography. Small amounts of trehalose were tentatively identified in extracts from noninfected hypocotyls, whereas up to 20× this level occurred in extracts from infected hypocotyls. Inositol declined in the infected hypocotyls while glucose increased to about 4× the level in noninfected hypocotyls. Fructose and mannose concentrations increased about 2-fold in the diseased hypocotyls, whereas the galactose concentration was about one-third that of noninfected hypocotyls.
Translocation of 14CO2 sugar photosynthates into infected hypocotyls was more rapid than that into noninfected hypocotyls. The infected tissues also exported less sugar than the non-infected tissues. Sucrose was the major sugar translocated into the hypocotyls of both infected and noninfected plants.
