Can lateral redistribution of auxin account for phototropism of maize coleoptiles?



Can lateral redistribution of auxin account for phototropism of maize coleoptiles?



Plant Physiology 81(1): 306-309



From studies of the elongation growth following the application of IAA in lanolin to the tip of maize coleoptiles, it was concluded that endogenous auxin was limiting for growth, that there was an approx. linear relationship between auxin concn and growth rate over a range covering those rates occurring in phototropism, and that an auxin gradient established at the coleoptile tip was sustained during its basipetal transport.
