[Aroid-l] leaf variegation in A. titanum

From: mmarcotr at email.smith.edu (Michael Marcotrigiano) on 2007.09.24 at 16:08:18(16331) Judging by the appearance I would not rule out aneuploidy or virus. It does not look like a plastid sorting out chimera as seen here http://www.exoticfinches.com/plants/amorphstory.htm _______________________________ +More Michael Marcotrigiano, Ph.D Director of the Botanic Garden and Professor of Biological Sciences Smith College, Lyman Conservatory, College Lane Northampton, MA 01063 email: mmarcotr at smith.edu voice: 413-585-2741; fax: 413-585-2744 www.smith.edu/garden ---------------------------------------------------------------------------------- If a cluttered desk signs a cluttered mind, Of what, then, is an empty desk a sign? ~ Albert Einstein. - >>> "StroWi at t-online.de" 9/24/2007 2:47 AM >>> Sorry folks, I forgot the subject line.....

As far as I know the seed was obtained from the Botanical Garden in Bonn. Has anyone seen something similar; and how often is this leaf pattern found? The question is why this plant is variegated. The gardeners of the Berggarten suspect a virus equivalent to one that causes variegated plants in Abutilon. I would rather vote for an L2 chimaera. Or should transposons be involved???? Looking forward to any comment, Bernhard.
