Plasma membrane electron transport reactions and associated proton secretion were studied in boron-deficient carrot cells. It was found that the hormone-sensitive plasma membrane NADH oxidase was inhibited by boron deficiency and that under such conditions activity could be restored by exogenous boric acid with or without 2,4-dichlorophenoxy acetic acid. Gramicidin, a channel-forming protonophore, further stimulated NADH oxidase by carrot cells. Proton secretion, associated with plasma membrane… CONTINUE READING
