A point mutation in the IAA14 promoter enhances callus formation and regeneration
{{output}}
Callus formation induced by auxin accumulation is considered the first step of in vitro plant regeneration. In Arabidopsis, degradation of the Aux/IAA protein, IAA14, in response to auxin signaling, which activates the AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 ... ...
