Re: [aroid-l] variegated

Chloroplasts have their own genes (being derived from bacteria in
evolution) and they divide and occupy cells. When a chloroplast mutates
it can become white and when it divides it is in the cell with other
green ones. Eventually some cells sort out to all green, some all white,
most mixed, giving you a marble pattern. I am NOT sure this is the cause
of variegation in 'shattered glass' but the phenotype of shattered glass
is consistent with this mode of chloroplast inheritance. Until I do
crosses with it I can't unravel it for sure.

Yes, you're right about that.  Those hosta used for breeding are not so
easy
to find, just like this konjac:-)
But it still is a bit weird to me that something genetic does not
happen all
over the plant.
Any explanation for that?  If not, I guess I'll just have to accept
the
facts:-)

Best,
Michael
