Low diversity among the cultivated stuff, which is quite distinct from the wilds. All due to clonal propagation. No concrete recommendations apart from conserving all you can find. Pity.

Wild sorghum and aridity
I’m not entirely sure why, but I get the occasional alert from something called the FAO GeoNetwork when a new dataset comes online. This morning it was global aridity. It’s not really very detailed or anything, but when something like that is available in a format that Google Earth can handle, I can very rarely resist the temptation of clicking on the link. So, in case you’re interested, this map shows the distribution of African wild Sorghum accessions in Genesys (that’s the little blue dots, which you’ll be able to see better if you click on the image — sorry about that) superimposed on that aridity thing.
This suggests to me that if you want really drought-tolerant wild Sorghum germplasm, the Sahel is where to look, rather than southern Africa or South Asia. But what about Australia, I hear you ask? Well, Genesys doesn’t have any wild sorghum from Australia, but GBIF does.
Here we’re looking at herbarium specimens, remember, rather than genebank accessions, but it does seem that Australia may be a slightly better bet for aridity-adapted wild sorghums than Africa. But for hyper-arid adaptation, it’s the Sahara for you.
Is this automated Musa phylogeny any good?
PhyloGenerator is “an open-source, stand-alone Python program, that makes use of pre-existing sequence data and taxonomic information to largely automate the estimation of phylogenies.” Sounds intriguing, no? I found out about it via this Twitter exchange with Rich Grenyer:
@rich_ @Phalaropus Sure, of course!

He very kindly shared his automatically generated Musa phylogeny, which is reproduced below. I’m afraid you’ll have to click on the image to read the species names.
So now I’m reaching out to all you banana taxonomists out there. Does this make any sense?
The Indonesian fires and crop wild relatives
I know what you’re wondering. You’re wondering whether those fires in Indonesia which are causing so much trouble with haze in Singapore and other neighbouring places are also endangering any crop wild relatives back home. Well, thanks to the following Twitter exchange with the GIS people at Kew, I now know (or have been reminded, actually) that NASA makes available global data on active fires:

We can of course mash that up in Google Earth with, say, the distribution of wild rice (Oryza spp) from Genesys. That would be the little pale blue circles in the map reproduced below.
Which does suggest that at least some of the Indonesian fires may be occurring in wild rice habitats. They may actually be beneficial to some of the weedier species, though, for all I know. Anyway, as ever, it’s nice to have the data. And, just as importantly, be able to play with it.
