Here is an update on some of the cultures. While somewhat difficult to see in the photos, I have been encouraged by the depth of color in the first flat "vegetative" leaves (seen as a fringe along the top of the 18 September photo) -- produced after transfer to a media without any plant growth regulators (PGRs). They are of a deep, deep red, similar to that seen in a kidney bean . . .
