| Abstract: | The effects of ambiol, a new growth regulator, on stem growth and morphological features of stem development have been compared in regenerants of potato (Solanum tuberosum L., var. Desire) plants transgenic for a defensin gene and in original potato plants. The original and transgenic plants exhibited differences in shoot development, which were observed both in control settings (no ambiol) and in the presence of various ambiol concentrations. In addition to normal plants of both forms, plant regenerants with morphological deviations were present in ambiol-treated groups. It is suggested that the abnormal shoot development observed in original and transgenic potato plants treated with ambiol is associated with (a) hormonal changes caused by expression of the defensin gene in the transgenic plants and (b) effects of ambiol on the hormonal balance of the plants. |
