[Aroid-l] Varigated ZZ`s and more.

From: plantguy at zoominternet.net (Daniel Devor) on 2007.10.29 at 22:25:42(16630) 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unpublished observations from my own back-yard lab :o) I personally never cared enough to do the appropriate concentration-response studies to see if I could select a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 just me!
