Re: [nise] Re: Hosta Variegation (clarification)


I wish I had a microscope, I would go out and look for you.  It is an
interesting explanation of the type of variegation found in these plants.
If it is true, it is more evidence that there might be a gene regulating
chloroplast development that is moving around the genome.  In this case it
would come under the regulation of genes related to stomatal development.
It could, however, also be a developmental problem in the leaf.  I have
mentioned to several geneticists that Hosta would be a good subject of
research because of its unique ability to variegate so readily.

Thanks for the post,

Jim Anderson
