- Abstract
Cytokinin-like substances in both healthy and infected (Plasmodiophora brassicae Wor. strain S) Toots of Brassica campestris L. ssp, pekinensis cv. Granat have been tentatively identified and quantified by HPLC. The isomers of the cytokinins could be separated on a reversed phase column using a gradient elution with increasing amounts of methanol. Secondary Plasmodia were isolated mechanically from Plamodiophora brassicae infected roots. The time course of adenine uptake and its conversion to cytokinins were investigated. Evidence is presented for the in corporation of [U-14C]-adenine into trans-zeatin by secondary plasmodia.
