摘 要：Endogenous auxin is an important regulator of in vivo organ development,but its role in in vitro organogenesis is *** has been observed that the basal end of epicotyl cuttings of juvenile citrus seedlings produces fewer shoots than the apical ***,we report that elevated endogenous auxin levels in the basal end of citrus epicotyl cuttings are inhibitory for in vitro shoot *** transgenic citrus plants expressing an auxin-inducible GUS reporter gene,we have observed elevated levels of auxin at the basal end of stem cuttings that are mediated by polar auxin *** endogenous auxin or blocking polar auxin transport enhances shoot *** auxin transport inhibitor,N-1-naphthylphthalamic acid(NPA),can also enhance shoot organogenesis independent of its action on polar auxin ***,we demonstrate that the promotional effects of depleting endogenous auxin or blocking polar auxin transport on shoot organogenesis are *** study thus provides meaningful insights into possible roles of endogenous auxin and polar auxin transport,as well as auxin–cytokinin interactions,in in vitro shoot ***,our results may also provide practical strategies for improving in vitro shoot organogenesis for citrus and many other plant species.
