Biochemical Bases for the Loss of Basipetal IAA Transport with Advancing Physiological Age in Etiolated Helianthus Hypocotyls: Changes in IAA Movement, Net IAA Uptake, and Phytotropin Binding
Basipetal transport of [(14)C]IAA in hypocotyl segments isolated from various regions of etiolated Helianthus annuus L. cv NK 265 seedlings declines with increasing physiological age. This decline was the result of a reduction in both transport capacity and apparent velocity. Net IAA uptake was grea...
