Oxidation of NADH by intact segments of soybean hypocotyls and stimulation by 2,4-D.

Intact sections of soybean cut from regions of cell elongation of hypocotyls of etiolated soybean seedlings oxidized externally supplied NADH (NADH is an impermeant substrate). The oxidation of NADH by 1-cm intact sections was stimulated by the plant growth factor 2,4-dichlorophenoxyacetic acid (2,4-D). The optimum concentration of 2,4-D for stimulation was… CONTINUE READING
