Bill Gates on genebanks and their databases

From Bill Gates’ annual letter on the work of his foundation:

There are three things that modern agrotechnology brings to this seed improvement process. The first is simply the ability to gather plant samples from all over the world and use databases to keep track of thousands of plants grown under different conditions.

The second is sequencing and the third is transgenics, in case you were wondering. One of these days, I’d like to take Mr Gates down into Genebank Database Hell. But hey, we’re working on it. And the Foundation is helping.

Keeping up to date with taxonomy made easier

Yesterday I was invited to submit one of my photos to the Flickr pool on Systematic Botany. Yes, I know. The media ought to be alerted. But I point this out less to draw attention to my photographic prowess than to highlight the fact that there is in fact a Flickr pool on Systematic Botany, and that it is a lot of fun. Exploring the discussion forum led me to an old news item about staff at the National Museum Cardiff and Kew naming a whole bunch of new Sorbus species, and not from some isolated corner of the world either, but England and Wales.

Some of these trees have probably developed recently and are examples of on-going evolution of new species. Others are older types which have been known for some time but are only now described as ‘species’ thanks to modern DNA methods.

Some Sorbus species have economic uses, and the taxonomy is made horrendously complicated by rampant hybridization and apomixis.

Coincidentally, IIALD had a piece on a new scheme “supporting and promoting the development of persistent and openly accessible digital taxonomic literature.” I wonder whether making photographs of plants available through Flickr or some other image sharing site might contribute to this worthy cause.

Yasuní National Park disappoints lovers of crop wild relatives

The Yasuní National Park in Ecuador is apparently the mother of all biodiversity hotspots, “home to the most diverse array of plants and animals in South America and possibly the planet.” And not only that, it may actually continue to be so, unlike many other protected areas.

There are hints that the park could have extra conservation value in a warming world. Yadvinder Malhi, an ecologist at Oxford specializing in the Amazon, said that nearly all climate models simulating the impacts of global warming show the area staying wet even as other parts of the vast basin get drier.

Yeah, but has it got any crop wild relatives, I hear you ask. Well, I asked our friend Julian Ramirez at CIAT, who works with Andy Jarvis. Alas, only one species turns up in Yasuní from the genera of the main South America crops for which he has a decent number of geo-referenced observations (Arachis, Solanum, Phaseolus and Manihot): Manihot brachyloba. Andy, who did his PhD in Yasuní, says he also saw wild cacao and pineapples there. No doubt Julian is putting together the data for those genera as we speak.

Yasuní is of course in the Amazonian lowlands. Wild relatives of Phaseolus and Solanum are in other, nearby protected areas in the Ecuadorian Andes. But that’s another story. For this one: thanks, Julian.
