Role of AUX1 in the control of organ identity during in vitro organogenesis and in mediating tissue specific auxin and cytokinin interaction in Arabidopsis.

Abstract excerpt

Classic plant tissue culture experiments have shown that exposure of cell culture to a high auxin to cytokinin ratio promotes root formation and a low auxin to cytokinin ratio leads to shoot regeneration. It has been widely accepted that auxin and cytokinin play an antagonistic role in the control of organ identities during organogenesis in vitro. Since the auxin level is highly elevated in the shoot meristem...
