Abstract

Models of plant growth and development propose that changes in cell polarity are mediated by gradients of the plant hormone auxin. With use of gas chromatography-mass spectrometry, we measured the redistribution of endogenous auxin in stems of quaking aspen trees (Populus tremuloides) after wounding. Persistent (lasting at least 24 hours) auxin gradients were observed in the region of the cambium where cell polarity was changing. A computer model of the auxin redistribution shows agreement with measured concentrations.
