Does increase in copy number of resistance gene increases resistance?
This is post no. 1 under the main topic.
So my question is-
will the plant be more resistant to particular antibiotics (say hygromycin) if it were to be transformed with multiple copies of hygromycin gene (hph)?
The copies of the hph gene might not be too near to each other to avert RNA interference.
Then, provided they were distantly integrated, if not, integrated in different chromosomes in the genome, does the plant with higher copies of the resistance gene confer higher resistance?
