Re: Varigated ZZ`s and more.
Of course, there are others, like FDA-approved antibiotics that are known to
cause things like read-through of premature stop codons that are actually
clinically useful that also cause plastid mutations so a careful literature
search might be good for those with a more scientific bent...and YES, these
antibiotics if used in too high a concentration cause total albinism in both
Arisaema and Amorphophallus seedlings....unpublished observations from my
own back-yard lab :o) I personally never cared enough to do the appropriate
concentration-response studies to see if I could select a variegated clone
(for me, this was a simple curiosity thing as we had the antibiotics in my
research laboratory anyway for totally different purposes) as I do not know
why in the world anyone would want one in the first place.....but that is
Gibsonia, PA where we finally had our first frost last night :o)
