Prota4U: stopped making sense.
I’ve only lately begun to sip from the firehose that is Twitter. Many things about it puzzle me, but not unduly. One thing I do find odd is the feed called Prota4U. It’s an arm of The Prota Foundation, and Prota stands for Plant Resources of Tropical Africa. The Foundation’s aims are entirely laudable:
It intends to synthesize the dispersed information on the approximately 7,000 useful plants of Tropical Africa and to provide wide access to the information through Webdatabases, Books, CD-Rom’s and Special Products. … The objectives are to bring the published information, now accessible to the resourceful happy few, into the public domain. This will contribute to greater awareness and sustained use of the ‘world heritage of African useful plants’, with due respect for traditional knowledge and intellectual property rights.
One could quibble with the details, but the overall idea is sound. Prota4U — groovy to the nth degree — publishes an endless stream of tweets, roughly one every three minutes while it is awake, that don’t link to anything, often don’t say much, and frequently have nothing to do with useful plants of Tropical Africa. This particular rant was occasioned by this tweet:
Avena sativa — It has a floury texture and a mild, somewhat creamy flavour.
Fascinating. Just the thing to nibble on with my breakfast oats. But so what? And the tweet doesn’t go anywhere either. Annoyed, I Googled that descriptive phrase. And found it in two places. One, Plants for a Future’s database entry for Avena ludoviciana. The other, this tweet from Prota4U:
Avena byzantina – It has a floury texture and a mild, somewhat creamy flavour.
That too goes nowhere.
Of course in the greater scheme of things what Prota does with its information is no concern of mine, and I could simply stop following. I’m just totally puzzled by what it thinks it is doing. Someone, anyone, put me out of my misery, please.
Nibbles: Rice conservation and use, Tunisian genebank, Buno, Popcorn, Sustainability, Brazilian social networking, Strawberry breeding, Sunflower genomics, Climate change and fisheries
- Lots of Indian rice in the IRRI genebank. Any of it being used to develop drought-tolerant varieties?
- Lots of journalists in the Tunisian genebank.
- How they make coffee in Ethiopia.
- How they make popcorn the world over. You sometimes get popcorn (or popped sorghum) with coffee in Ethiopia, now I think of it. And since we’re on an Ethiopian kick, fancy some enjera? Gary Nabhan did.
- “Productivity vs. sustainability is a ‘false choice.’” Well I never. And probably not news to these people either, or these. But to these guys?
- A Twitter roundup from Embrapa.
- Ugly hybrid of two wild strawberries may cause allergies.
- Explanation of evolution of doubled genes in wild and cultivated sunflowers certainly causes pain in brain.
- Some good climate change news for the Atlantic croaker. Being a glass-totally-empty kinda guy I predict it tastes like shit.
Measuring diversity in Tibetan walnuts
You collect leaves from 220 walnut trees of two morphologically very distinct species (Juglans regia and J. sigillata) from two unrelated groups of families of villagers in each of six different villages in Tibet. You get the gene-jockeys to do their microsatellite stuff on the leaves. You calculate the contribution of species, of the kin relationship of the growers and of village to genetic diversity. You expect the biggest genetic differences to be between species.
You are wrong.
Yes, the “species,” which look totally different, are in fact indistinguishable genetically. But there were significant differences among villages, and smaller but still significant differences between unrelated families of farmers within villages. So, you might be particularly interested in certain traits, for improvement say (and so are the farmers: walnut landraces in this part of Tibet are often named after fruit phenotypes). But — in this case — morphology is not a great guide to the totality of the underlying genetic diversity. So you can’t use it alone for conservation.
Which is also the conclusion researchers in Benin arrived at in their study of another tree, akee (Blighia sapida), also just out. A conservation and use (domestication, in this case) strategy “should target not only the morphotypes recognized by local populations but should also integrate the population genetics information.”
Does this amount to a general rule?
