Foliar modifications induced by inhibition of polar trans- port of auxin

摘要

The effects of auxin polar transport inhibitors, 9- hydroxy-fluorene-9-carboxylic acid(HFCA); 2,3,5- triiodobenzoic acid(TIBA)and trans-cinnamic acid(CA) on leaf pattern formation were investigated with shoots formed from cultured leaf explants of tobacco and cultured pedicel explants of Orychophragmus violaceus, and the seedlings of tobacco and Brassica chinensis. Although the effective concentration varies with the inhibitors used, all of the inhibitors induced the formation of trumpet-shaped and/or fused leaves.
