Hydrocarbons associated with the developing microspores in the anther loculus of Tulipa cv. Apeldoorn were investigated. They occurred mainly at chain lengths between C19 and C29. At the lower chain lengths the n-alkanes, at higher chain lengths the

Chalcone synthase in roots ofPisum sativum andPhaseolus vulgaris was demonstrated enzymatically and immunochemically. In situ localization by indirect immunofluorescence revealed that chalcone synthase is chiefly present in the lateral regions of the

1. The unequivocal chemical composition of sporopollenin is unknown. Ir was often hypothesized that sporopollenin represents a derivative of carotenoids and/or carotenoid esters. Proceeding from this working hypothesis the influence of inhibitors of

Three distinct glycosyltransferases have been isolated and partially purified from anthers of Tulipa cv. Apeldoorn. The following designations are proposed; UDP-glucose: flavonol 3-O-glucosyltransferase (GT-I), UDP-rhamnose: flavonol 3-O-glucoside rh
