Re: color separation in electric field

A more interesting explanation for the color separation George reported in
the Rotala macandra in the electric field would be that it is not the
micronutrients that are concentrated in one or the other end of the plant,
but the actual pigments.  What he probably has is an electrophoretic
equiblirium based on the overall charge distributions of the individual
pigment molecules.  It is assumed that the color of Rotala is a result of a
number of pigments.

The ability to achieve electrophoresis in living organisms is an enormously
significant development that has applications in concentrating medicines at
sites within the organism.  The implications  for medical chemotherapy are
mind-boggling!  Think in terms of a Nobel Prize, George!  Also, get the
process patented!
