Abstract
The activity of the shikimic acid pathway during shoot initiation in tobacco (N. tabacum L. Wisconsin 38) callus was examined. Enhancement of the activities of 3-deoxy-D-arabino-heptulosonic acid 7-phosphate synthase, shikimate kinase, chorismate mutase, and anthranilate synthase was observed during culture of tobacco callus under shoot-forming conditions in comparison to tissue cultured under non-organ-forming conditions. Confirmation of these findings was obtained by examining the incorporation of D-[14C]glucose into quinic and shikimic acids and of [14C]shikimic acid into tyrosine, phenylalanine, and tryptophan.This publication has 18 references indexed in Scilit:
