Thus far, no evidence has been presented that the rol genes (Ng rol) of Nicotiana glauca (Furner et al. 1986) are expressed in this plant. However, we found that the Ng rol genes were transcribed in genetic tumors formed in hybrids of N. glauca x N. langsdorffii. During the culture of such genetic tumors, the level of transcription of Ng rol B increased while that of Ng rol C decreased in parallel with an increase in the endogenous auxin level in the tissues. Moreover, the transcription of… CONTINUE READING
