Metabolism of 14C-Pebulate in Seedling Tobacco
Published online by Cambridge University Press: 12 June 2017
Abstract
Extracts from the roots and shoots of tobacco (Nicotiana tabacum L. ‘Kentucky 14′) seedlings treated with 14C-pebulate (S-propyl-1-14C butylethylthiocarbamate) were separated into various organic and aqueous phases to determine the distribution of 14C. In the roots the organic acid-carbohydrate fraction became the most highly labeled fraction with time while in the shoots the fraction containing the sterol esters and oligoglycerides was the most highly labeled early in the treatment period but gradually lost radioactivity at later time intervals. Pebulate was not recovered in detectable amounts in either the leaves or roots.
