The effect of plant water potential on the activity of indoleacetic acid oxidase was examined. It was found that with increasing plant water deficit the activity of indoleacetic acid oxidase increased. Higher activies of this enzyme are known to be associated with older tissues and lower endogenous auxin levels. It is suggested that while water stress may adversely affect a variety of physiological processes, increases in the activity of indoleacetic acid oxidase may provide plants with a drought adaption mechanism.
