Is nutrition research any use without genetics & genomics?
That’s the question Keith Grimaldi of the Eurogene project asks in the latest post on his newish blog. By “genetics” he means human genetics.
His answer?
Without genetics & nutrigenomics, epidemiological nutritional research will remain “mostly harmless”. Or to paraphrase a less amusing person maybe it’s like trying to govern the Italians — “not difficult, just a waste of time”
We’ve suggested something similar here a couple of times, albeit it much less eloquently than Dr Grimaldi. Are the people designing projects aiming to improve the nutritional status of communities, whether based on biofortification through genetic modification or diversity-based approaches, listening?
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.
Bees? We don’t need no stinkin’ bees
It’s obvious really. If you have a problem in a billion-dollar industry — almonds — because your workforce — bees — are dying like flies, what do you do? Forget the bees. Breed almonds that don’t need pollinators!
Which is exactly what breeders at the USDA are doing. Actually, self-pollinating almonds are apparently nothing new. There’s a Spanish variety, Tuono, ((Don’t Google it unless you’re a motorcycle freak.)) that “has been around for centuries”. But it doesn’t suit the almond industry of California. Even before Colony Collapse Disorder became a problem the USDA geneticists were busy using Tuono as the pollen parent in a series of crosses, because in addition to dispensing with bees it has other good properties. And now eight new, self-pollinating varieties have been evaluated. In time, they may replace the standard, bee-demanding variety Nonpareil, which apparently accounts for 37% of California’s almond trees. ((Down from 45%, according to an undated FAO document.))
Oh, and if you’re really into almonds, you probably already know about The Almond Doctor.
Costs, benefits, and the search for disease resistance
An epidemic of Fusarium head blight swept through the United states between 1998 and 2000, costing the wheat industry an estimated US$ 2.7 billion. That’s right: billion.
Salvation came from Chinese and Japanese landraces, especially a Chinese wheat called Sumai 3. To prepare for the inevitable mutation of the fungus, scientists at the USDA have broadened their search for resistance. They examined 87 Asian varieties of wheat, many of them old landraces, and found good levels of resistance in 26 of them. Better yet, some of the resistance genes seem to be different from the ones derived from Sumai 3, which means that they might offer protection against different varieties of the fungus.
Just knowing that various resistance genes exist, and having markers to select more resistant crosses from breeding efforts means that future outbreaks can probably be more effectively dealt with, which is reassuring. More to the point, for our purposes, this research raises again the question: how can anyone doubt the value of genebanks? Just one disease cost just one country US$2.7 billion over three years. Genebank accessions contain the solutions. Do you really need to know the cost of every accession to decide whether genebanks are worthwhile?
