fascination variegation

Hosta-Open sure seems to be quiet lately.  I guess everyone must be 
out in their gardens working.  Hostas in the greenhouse have been 
coming up for awhile now and there is one hosta that is sheading some 
light on variegation for me.

Several years ago I divided Fascination.  I got a whole lot of cream 
centered plants of no landscape value, although I kept one or two for 
research purposes, and an all green form.  The all green form, which I 
call Green Fascination, is vigorous and makes a nice landscape plant. 
I've been propagating the all green form as part of my variegation 
study and now I have a plant emerging from the all green form that is 
showing streaked variegation, although, at this time, not as strong as 
in Fascination, but its only the first leaf.

While there is some possibility that some hostas are variegated due to 
mutated chloroplasts, I'm more inclined to think that transposible 
elements are more likely responsible for hosta variegation.  The fact 
that a variegated hosta that turns to a solid color and then back to a 
variegated form would appear to lend support to the transposible 
element theory.  I have an all green form of Gold Standard, an all 
pale green form of Golden Tiara, an all blue/green form of Great 
Expectations and I might have an all green form of Paul's Glory.  Now, 
if I can get back variegated froms from these all solid colored sports 
from variegated hostas, then I would think that would give even more 
credence to the transposible element theory.  Any thoughts?
