formation​

Answer 1

Answer:

The shoot regeneration efficiency of tobacco leaf discs from the G-box-deleted mutant (–G) and that of the control native g2bPAL promoter (g2b) was about one half to one third of the mutants lacking the M, L and P’ boxes, –M, –L and –P’, respectively, and the transgenic tobacco –G and g2b grew very slowly (data not shown). It is uncertain whether the tobacco cells in the leaf discs transformed with the constructs harboring the M, L and P’-boxes grows well or not. However, the fact that deletion of only one box, M, L or P’-box, did not suppress the growth indicates complicated interaction among these boxes.
