Auxin content and IAA-protector activities in cultured crown gall cells were measured at various points of growth in subculture. A coincidence was observed between the change in IAA content and IAA-protector activities in the cells: high auxin contents with high IAA-protector activities were obtained at the late log stage, and low auxin contents with low IAA-protector activities at the middle log and at the stationary stages. On the other hand, IAA-destruction activities in the cells increased slightly throughout the growth period of the cells. Addition of 2,4-D to the culture depressed the auxin content and accelerated the IAA-destruction activity in the cells. These results suggest the existence of a mechanism of negative-feed-back control of auxin in crown gall cells.
