Diversity everywhere

We cannot be the only ones to have noticed that in the past couple of weeks there has been a spate of papers on different aspects of the link between plant diversity and ecosystem functioning:

Needless to say, we’re working our way through that little lot, so you wont have to. More soon. Unless, that is, someone out there wants to do the honours?

Mapping drought risk

Just a quick follow-up to the rhyming couplet on water-related stresses in the just-published Brainfood. The Center for Hazards and Risks Research (CHRR) at Columbia University, which we have mentioned here before in connection with tsunami risk, also has data on Global Drought Hazard Distribution.

With a little R-related effort by Robert 1 you can get a Google Earth file, which looks like this for Asia. 2 I’ve also added MODIS fire hotspots for the past 24 hours, merely because I can. That would be the little fire icons.

And that means you can mash up drought risk with germplasm origin (from Genesys, say), in this case from Chad as an example.

Which is a great thing to be able to do because as we have just had reconfirmed by our friend Dag Endresen, the origin of germplasm allows you to make some predictions about its performance.

The John Innes Centre reaches out to genebank users

The Germplasm Resources Unit at the John Innes Centre has a new e-newsletter that you can subscribe to. The first issue is just out, and it’s well worth reading. Just to give the lie to my contention, expressed not a day back, that genebanks and users don’t talk enough, the newsletter is described…

…as a further channel of communication with our user community and raise awareness of recent activities and to flag the work of the collections and what we can offer. In this edition we highlight some of our activities of the past growing season while also providing a flavour of some of the work we are planning for 2011.

Germplasm documentation is a two way street

I don’t blame Pat Helsop-Harrison for not donning the fire-proof suit to find his Ug99 resistant lines, or whatever. I really don’t. Why would anyone venture into Genebank Database Hell, when they have such a friend in Google? I only do it myself because, well, I get paid to. But although the genebank community bears some of the responsibility for this situation, and is indeed trying to do something about it, part of the problem lies, I’m sorry to say, with the users of the data.

I’ll give you an example. Over at Vaviblog Jeremy has a post about the domestication of African rice. He describes some fancy DNA work from researchers in China who pinpointed the area of domestication of Oryza glaberrima by comparing the sequences of 14 genes in 20 accessions of the cultigen with 20 accessions of the progenitor, O. barthii. And where did they get that material?

All accessions were obtained from seeds provided by the Genetic Resources Center of the International Rice Research Institute at Los BaƱos, Philippines.

That’s great, of course. This kind of research use of the international collections is exactly what one wants to see. That’s what they’re there for. But when I asked IRRI about this, they said that “these authors aren’t included in the names of recipients in our database.” So they must have got the seed indirectly in some way. Again, fine. But when users use seed from a genebank like this, it would benefit everyone — the genebank itself, future users — if they fed back their results in some way, to add to the store of information the genebank has on its accessions.

Now, not all genebanks make this as easy to do as they could. That’s why we have on occasion suggested a social networking approach to germplasm documentation, to resounding silence. But users don’t go out of their way much either. Until the two communities come together more on this, the best way to find seeds will probably continue to be Google.
