Talk:International Grape Genome Program

A fact from International Grape Genome Program appeared on Wikipedia's Main Page in the Did you know column on 16 April 2007. The text of the entry was as follows:

Did you know... that the International Grape Genome Program in Adelaide, Australia discovered that white grapes only exist today due to a rare genetic mutation that took place thousands of years ago?

A record of the entry may be seen at Wikipedia:Recent additions/2007/April.

Biological copyedit needed![edit]

I've created this article primarily due to its bearing on viticulture and don't profess to anything more than an basic understanding of applied genomics. It would doubtless benefit from either elaboration, editing or even re-writing in parts, especially as the project is still in its early stages. I would also encourage any citeable dissenting views on the subject of GM grapes. mikaul^talk 23:12, 11 April 2007 (UTC)[reply]

Comment[edit]

"White wine residues have been discovered in ancient Egyptian pottery remains, hence the conclusion that this mutation must have occurred at least three thousand years ago." I suggest this should read something like "Wine residues containing white wine grape genetic material have been discovered in ..." to avoid implying that white wine is necessarily made from white wine grapes, when that is not the case.

Good point, but I'm not sure if that's true; the two sources I've seen quoting the 'Egypt' comment make no reference to any genetic testing and given that it refers to research prior to the grape genome program, I have my doubts. Of course if you can find a source describing the tests carried out on this residue (in a vesel dicovered in Tutankhamun's tomb, apparently) I'd agree it would be a lot less ambiguous. It 's a bit of a wild supposition, is my feeling, more of a nice PR way of saying that all known white grape varieties have a lineage predating the earliest discoveries of wine, but that's the way it was announced. mikaul^talk 10:29, 16 April 2007 (UTC)[reply]

I also could not find more info on whether it really was white wine based on white grapes. It really puts in doubt the whole conclusion that the mutation occurred three thousand years ago. Maybe it would be better to weaken the "hence the conclusion" to "hence there is a theory" or something else less definite. Randomcomments 20:01, 20 April 2007 (UTC)[reply]

You're right :) I've qualified the statement. mikaul^talk 23:16, 20 April 2007 (UTC)[reply]
