Abstract
In vitro shoot organogenesis from Arabidopsis hypocotyl explants was stimulated by 1 mMproline, and to a lesser extent by 5 mM proline, butinhibited by inclusion of 10 mM proline in thehormonally-supplemented regeneration medium. Theability of low concentrations of the prolineanalogues, azetidine-2-carboxylate and thioproline toovercome the stimulatory effect of 1 mM proline, anda slight increase in the stimulative effects of 1 mMproline by D-proline, are consistent with an importantrole for the interconversions of proline and itsprecursors in regulating cell division anddifferentiation.
