Ectopic expression of the Brassica SHOOTMERISTEMLESS attenuates the deleterious effects of the auxin transport inhibitor TIBA on somatic embryo number and morphology

▶ Proper auxin flow is crucial during the induction phase of Arabidopsis somatic embryogenesis. ▶ Over-expression of SHOOT MERISTEMLESS attenuates the effects of auxin flow inhibitors. ▶ Normal auxin distribution is retained in STM over-expressor lines treated with auxin flow inhibitors.
