The 5th International Symposium on the Taxonomy of Cultivated Plants will take place in Wageningen, the Netherlands in October 2007. Apparently, an international association representing people interested in crop taxonomy is to be launched.
Grape origins
A paper in Conservation Genetics identifies (not, I think, for the first time) the Caucasus as the centre of diversity and origin of wild grapevine, at least based on microsatellites. A genetic refugium was detected in Sardinia, and it would be interesting to know whether the plastid lineage that is fixed there is responsible for the high levels of procyanidins in some local wines.
Wet Wet Wet
The GlobWetland project uses remote sensing and GIS to address the threats faced by the world’s wetlands. Do we know how many crop wild relatives are found in wetlands? Or even how threats to wetlands affect genetic diversity in adjacent agricultural areas? I think plant genetic resources people and the ecosystem conservation crowd need to link up a bit more, and I can’t help thinking that wetlands might be pretty good meeting ground.
Fried purple tomatoes?
Would you eat a purple pizza? Breeders at Oregon State University are hoping you would, because they’re a couple of years away from releasing a purple tomato hybrid, the colour apparently coming from a wild relative. Read about it here. Supposed to be better for you too…
Domestication my ass
Why was the Somali wild ass domesticated and not, say, the zebra? It’s a cantankerous animal at best. Washington University archaeologist Fiona Marshall is travelling the world looking at bones and wild populations, but she is also studying the behaviour of the St Louis Zoo’s five wild asses with Zoo researcher Cheryl Asa to seek “clues as to how they were turned into donkeys,” according to this article.
