Good news from ICARDA
From the recent New York Times feature on the ICARDA genebank:
Icarda’s entire collection houses seeds that have sustained the people of the Middle East for centuries, including some 14,700 varieties of bread wheat, 32,000 varieties of barley, and nearly 16,000 varieties of chickpea, the key component of falafel. The Lebanon seed bank houses about 39,000 accessions, and Morocco, another 32,000. Most of it is backed up in Svalbard.
You can read my own take right here on the blog. Here’s a shot of the new shadehouses I took during a visit a few months ago.
And do explore the ICARDA collection on Genesys.
Brainfood: Wild rice double, Paspalum evaluation, Industrial cassava, Intercropping meta-analysis, Chinese cotton, Power of words, Sampling, Biodiversity threats, Mung bean diversity, Chestnut core, Olive double, Durian genome
- Unlocking the genetic diversity of the undomesticated rice relative Oryza longistaminata. Natural hybrids discovered in IRRI genebank can accelerate breeding.
- Evidence for mid-Holocene rice domestication in the Americas. Another rice domestication?
- Evaluation and strategies of tolerance to water stress in Paspalum germplasm. A species for every purpose.
- Evaluation of Cassava Germplasm Accessions for High Tuber Yield and Starch Content for Industrial Exploitations. Watch Me681 take over. At least in India.
- Does intercropping enhance yield stability in arable crop production? A meta-analysis. Yes.
- Collection, Evaluation and Utilization of Cotton Germplasm. Over a thousand accessions!
- Treasure in the vault: The guardianship of ‘heritage’ seeds, fruit and vegetables. “Treasure” is a loaded term.
- Will the same ex situ protocols give similar results for closely related species? Yep.
- Global Hotspots of Conflict Risk between Food Security and Biodiversity Conservation. Madagascar is particularly worrying.
- Genetic diversity assessment of a set of introduced mung bean accessions (Vigna radiata L.). Germplasm from USDA genebank could be useful in China.
- Database of European chestnut cultivars and definition of a core collection using simple sequence repeats. Not sure you can call it European when 96 of 118 accessions are from Spain, but anyway.
- Genome of wild olive and the evolution of oil biosynthesis. Two genes explain all that oil…
- Did Greek colonisation bring olive growing to the north? An integrated archaeobotanical investigation of the spread of Olea europaea in Greece from the 7th to the 1st millennium BC. …which would have been intensely interesting to early Bronze Age elites.
- The draft genome of tropical fruit durian (Durio zibethinus). “Transcriptomic analysis showed upregulation of sulfur-, ethylene-, and lipid-related pathways in durian fruits.” You don’t say. Let’s engineer them into olives. Paleopolyploidizations here too, as in olives.
Osage orange outbreak
Took me a while to retrieve the proof I knew I’d need to fully convince Luigi. Here it is:
And in case the upload process somehow mangles the EXIF data (which are there in my copy) Lat is 41.88761166666666 Long is 12.466925 and, well, that’s all you really need.
Unravelling the role of biodiversity in the food-health nexus
Regarding the International Panel of Experts on Sustainable Food Systems (IPES-Food) report Unravelling the Food–Health Nexus, which we mentioned a couple of days ago, I hear that there was surprise in some quarters that biodiversity didn’t get more of a mention in the executive summary. In particular, high-placed sources are saying they would have preferred it to be at least mentioned under the first leverage point:
Leverage point 1: PROMOTING FOOD SYSTEMS THINKING. Food systems thinking must be promoted at all levels, i.e., we must systematically bring to light the multiple connections between different health impacts, between human health and ecosystem health, between food, health, poverty, and climate change, and between social and environmental sustainability. Only when health risks are viewed in their entirety, across the food system and on a global scale, can we adequately assess the priorities, risks, and trade-offs underpinning our food systems, e.g., the provision of low-cost food versus systematic food insecurity, poverty conditions, and environmental fallout of the industrial model. All of this has profound implications for the way that knowledge is developed and deployed in our societies, requiring a shift toward interdisciplinarity and transdisciplinarity in a range of contexts (e.g., new ways of assessing risks; changes in the way that university and school curricula are structured). Concepts such as “sustainable diets” and “planetary health” help to promote holistic scientific discussions and to pave the way for integrated policy approaches. Food systems thinking can also be encouraged on a smaller scale through initiatives that reconnect people with the food they eat (e.g., community shared agriculture, school vegetable gardens).
Apparently, though, when Prof. Molly Anderson presented the report, she described this as an oversight. If you were involved in any of this, and would like to tell us more, please do.
