Cassava around the world
Maybe it was hanging out at CIAT recently, but I seem to see cassava stories everywhere lately. Whether it’s chips for schools in Trinidad, or ethanol production in PNG, or breeding for disease resistance in Uganda, this tuber is everywhere. And don’t even get me started on the cassava revolution happening in Nigeria. International Year of Cassava anyone?
Nibbles: Barcoding, forests, social networking
- Trees to be barcoded. Including cultivated ones?
- This would be a good place to start.

Grape genomes galore
A little over six months ago researchers reported a high quality DNA sequence for the Pinot-Noir grape. 1 Now comes news that the USDA is planning to do a genetic analysis of more than 2000 additional grape varieties in its collection. These will not be full sequences. Rather, researchers will be looking for SNPs, 2 places where the DNA sequence differs by just one letter between two individuals. These SNPs are most useful as markers that can be used to identify areas of the DNA that may harbour important traits. Breeders and researchers can use them to track the inheritance of specific traits; USDA singles out disease resistance and berry colour. And that will speed up the breeding of new grape varieties.
I know hardly anything about the world of grape breeding, but someone out there may be able to tell me: when was the most recent introduction of a newly bred variety that gained any traction within the world of wine-making? 3
