Dr. Raghuram Badmi:

I do not see how these single base changes can be damaging or how they could influence anything because when we talk about chemical or natural mutagenesis, even in those processes we are talking about changing single base pairs or multiple base pairs and those are in random places.

In SDN-1 and SDN-2, however, of 50 million or 1 billion base pairs, we know exactly which letter has changed. I do not see how single base or multiple base changes can affect the environment, other than the plant itself.
