Anthocyanins in tomato fruits and plants

Jim Myers, a professor in the OSU horticulture department said:
“Indigo Rose's genesis began in the 1960s, when two breeders – one from Bulgaria and the other from the United States – first crossed-cultivated tomatoes with wild species from Chile and the Galapagos Islands, Myers said. Some wild tomato species have anthocyanins in their fruit, and until now, tomatoes grown in home gardens have had the beneficial pigment only in their leaves and stems, which are inedible.”

Tomato (Lycopersicon esculentum) accession LA1996 with the Anthocyanin fruit (Aft) gene has dark green foliage, elevated anthocyanin expression in the hypocotyls of seedlings, and anthocyanin in the skin and outer pericarp tissues of the fruit.
Vegetative tissues of Aft tomato plants are distinctive. Leaves are darker green and stems contain visibly more purple speckling than do wild-type plants.
Normal tomato genotypes routinely contain anthocyanin in the vegetative parts of the plants but not in the fruit.

He also stated that he had personally observed anthocyanin expressed in the leaves and stems of sprouts, seedlings and transplants although the purple coloring seems to disappear in mature plants, it is retained in the stems.
One more exciting thing he said was that he believes that anthocyanin is protective for plants going into cold weather at the end of the season!

I can't believe that Tollie sent you that first link which was when myers started all his breeding efforts and are known to everyone interested in anthocyanin,originally bred for dietary reasons.
A technician working in his lab took some of the early seeds in the project and offered them,illegally, at Dave's garden,specifically,P20 and another one.Myers did send some seeds to some folks who said they were breeders,some falsely, and they had to sign a contract they weren't to be shared with anyone.So what did I get in the mail, not asked for,were 4 fruits that were purple, I almost gagged when I tried to eat them.
Here's the direct link

I decided to go back to Tollie's website and see where he got his anthocyanin, and I'm glad I did

He got it from OSU Blue,which was the first one Myers worked with.
Nor the 2nd one either,which goes back to 2003 and is also very well known.
Now you need the one from England with the snapdragon gene in it and the one from Italy where no one knows where it came from.
Antho on just the fruit or just the foliage, or both? it doesn 't matter to me since I grow tomatoes mainly for taste alone,and that's what I'll always do,and yes,I've grown various variegated ones, angora ones and Stick and others,but mainly out of sheer curiousity.
Again,which scientific journals did you write abstracts for as I asked in the Shingles thread but you didn't answer yet.
Carolyn, who owes Tollie an e-mail sometime,we'll see.
