Effects of Some Auxins on IAA-Amino Acid Conjugate Formation in Carrot Tissues Transformed with Ti Plamids.

IAA-conjugate formation in carrot tissues transformed with aux- Ti plasmids was induced by exogenously applied IAA. When the tissues were treated with NAA or 2, 4-D, IAA-conjugate formation was also induced. This result suggests that IAA-conjugate formation may be generally induced by substances having auxin activity.On the other hand, 2, 4-D was not metabolized to conjugate form even when the transformed carrot tissues were treated with IAA. This suggests that the effect of 2, 4-D is different from that of IAA in carrot.
