AUXIN-INDUCED cell elongation can be inhibited by a variety of substances1. Among these inhibitors are the ammo-acid antagonists canavanine2, β-2-thienylalanine3 and ethionine4,5. This has been taken as evidence that protein synthesis is necessary for cell elongation6. Recently, Steward et al.7 have presented evidence that hydroxy-L-proline can also be an amino-acid antagonist. The growth of carrot callus explants could be blocked by this compound, and the inhibition could be completely… CONTINUE READING
