From: <plantguy at zoominternet.net> on 2006.12.22 at 14:48:05(14991) Well, there are many Arisaema with completely stable variegation of course, assuming you will allow all of the silver centered leaf forms to be included here, which I personally would, but maybe not others. Michael can comment on the stability of his Amorph, but it seems less than "stable" from reading his posts. There are of course many other things that cause variegation, including some chemicals that are not particularly harmful, i.e., antibiotics. Some of these characteristics of antibiotics have even been used to cause readthrough of premature stop codons in human disease in order to obtain full-length protein as I am sure many on this forum are well aware. A quick literature search will reveal a host of things that could be potentially used, although I would never suggest anyone use these things that does not atelast have some knowledge of fundamental scientific method and takes appropriate precautions. +More Of course, if you were really into this you could use a gene targeting approach or perhaps you could introduce a transgene on an inducible promotor, but this is now only in the realm of the true gene-jocks out there. best of luck with everyones experimentation, Dan Zone 6a (and insanely warm for this time of year) Daniel Devor, Ph.D. Department of Cell Biology and Physiology University of Pittsburgh ----- Original Message ----- From: Agoston Janos To: Discussion of aroids Sent: Thursday, December 21, 2006 2:11 PM Subject: [Aroid-l] Re: variegata aroids Ok, but can we stabilize variegation?

From: Tony Avent <tony at plantdelights.com> on 2006.12.22 at 21:09:24(14994) Jani: There are several other variegated aroids that haven't been mentioned. The most stable that we have grown is the Peltandra virginica with a narrow white edge. Pinellia tripartita 'Dragon Tails' is fairly unstable, but some of our seedlings are nearly solid gold and have been stable for several years. The pinstripe-type arisaemas aren't exactly variegated, but the highlighted silver vein effect is the same. There is also an Alocasia cucculata with a nice yellow edge that we have grown for years and now a new one is hitting the trade from Thailand with a golden center. Alocasia odora 'Okinawa Silver' is an unstable variegation pattern, but the pattern doesn't disappear. Ditto, the speckled A. 'Portadora'. The variegated Zantedeschia aethiopica 'Pershore Fantasia' holds for few years, but after that there is more green than variegated. I'm sure that there are more on the way.
