- Genetic structure within the Mesoamerican gene pool of wild Phaseolus lunatus (Fabaceae) from Mexico as revealed by microsatellite markers: Implications for conservation and the domestication of the species. Three, not just two, genepools.
- Farmer’s Knowledge on Selection and Conservation of Cassava (Manihot esculanta) Genetic Resources in Tanzania. Farmers exchange landraces, some of which are widespread and others more restricted in distribution. Only about 10% are new, but some have been lost.
- Urban cultivation in allotments maintains soil qualities adversely affected by conventional agriculture. You can farm in cities without killing the soil.
- Social institutional dynamics of seed system reliability: the case of oil palm in Benin. Farmers are being increasingly screwed.
- Natural occurrence of mixploid ginger (Zingiber officinale Rosc.) in China and its morphological variations. About a quarter of plants have both diploid and tetraploid cells, and they look different; no plants are wholly tetraploid. Weird.
- Conserving biodiversity through certification of tropical agroforestry crops at local and landscape scales. Certifying the coffee or cacao farm only is usually not enough.
- Is gene flow the most important evolutionary force in plants? May well be, which means that conservationists, among others, need to take it into account. Fortunately, they have the data-rich genomic tools to do so.
- Greater Sensitivity to Drought Accompanies Maize Yield Increase in the U.S. Midwest. It’s agronomy’s fault.
- Desiccation and storage studies on three cultivars of Arabica coffee. Yeah, not orthodox. Didn’t we know that already though?
- Seed-borne fungi on genebank-stored cruciferous seeds from Japan. There’s lots of them. And something needs to be done about it.
- Delivering drought tolerance to those who need it; from genetic resource to cultivar. In making synthetic wheat, you can fiddle with the AB as well as the D genomes, but then you have to phenotype properly under target stress conditions, and have a way of tailoring the resulting global public goods to local needs.
- The Effects of Agricultural Technological Progress on Deforestation: What Do We Really Know? Not as much as we thought we did.
- Large-scale trade-off between agricultural intensification and crop pollination services. Intensification bad for pollinators in France, so bad for agricultural productivity and stability.
- Achieving production and conservation simultaneously in tropical agricultural landscapes. Intensification good for smallholder income in Uganda, bad for birds. If only birds were pollinators.
Nibbles: Linux lettuce, Climate intelligence, European ag & CC, Italian forests, Sweet potato chains, Aroid podcast, Beer trifecta, CWR everywhere
- Totally forgot if we already linked to this latest pean to open source seed.
- Climate-smart agriculture described in three paragraphs.
- Hope someone explains it to European farmers, and soon.
- Italy is increasingly wooded. But only because farms are being abandoned. Maybe not climate-smart enough?
- If only those farms had better links to markets, like in E. Africa…
- Dutch food writer on the Jewish (maybe) origins of the Surinamese national dish. Gotta love edible aroids. Jeremy does his podcast thing.
- Step 1: Breed your hops.
- Step 2: Find a funky yeast.
- Step 3: Crack the Kenyan beer market.
- Back to real life: USAID’s brand new multisectoral nutrition policy. Now, then, what’s the betting that the agricultural interventions supported by USAID avoided the risks that such things often hold for nutrition (incomes, prices, types of products, women social status and workload, sanitary environment and inequalities)?
- SeedMap.org breaks down crop wild relatives.
- Somebody mention crop wild relatives? Yes, Sandy Knapp.
- Somebody mention parientes silvestres de cultivos? Yes, Nora Castañeda.
- How many CWR will go the way of Arabidopsis? Because southern populations of that species in genebanks are already doing better than local populations in northern sites.
- How many crop wild relatives in Kew’s meadows?
Brainfood: Yam tissue culture, Barley core, Date genome, Ecosystem services & land use change, Remote sensing and conservation, Okra diversity, Carob diversity, Mexican genebank project, Chicken skin music, Mongolian camel, Coloured rice
- Effect of various growth regulators on growth of yam (Dioscorea trifida L.) in vitro shoot tips. One small step for yam cryopreservation.
- The USDA Barley Core Collection: Genetic Diversity, Population Structure, and Potential for Genome-Wide Association Studies. 5 sub-populations: roughly, Mediterranean, W Europe, E Europe, Asia and Ethiopia. GWAS effective in locating important phenotypes.
- A first genetic map of date palm (Phoenix dactylifera) reveals long-range genome structure conservation in the palms. Lots of synteny with oil palm and coconut despite differences in genome size. And we now (probably) know how sex determination works.
- Economic evaluation of ecosystem goods and services under different landscape management scenarios. Agriculture usually wins at the expense of more “ecological” land uses, unless income from C and biodiversity (and timber) go up, or discount rates go down.
- Oil in the Sahara: mapping anthropogenic threats to Saharan biodiversity from space. You can spot biodiversity threats from space. More examples along the same lines.
- Genetic and morphological diversity of okra (Abelmoschus esculentus [L.] Moench.) genotypes and their possible relationships, with particular reference to Greek landraces. Much phenotypic variation, less AFLP variation, but geographically structured. Germination characteristics vary with ecology.
- Genetic diversity revealed by EST-SSR markers in carob tree (Ceratonia siliqua L.). First time carbob has been genotyped using microsatellites. And that seems to be the only reason why this work was done.
- Investigation of the genetic diversity of domestic Capra hircus breeds reared within an early goat domestication area in Iran. Breeds are diverse but geographically distinct, the western ones especially. Unlike sheep, which are moved around a lot more. Some evidence of inbreeding, which can and should be counteracted.
- Diversity Assessment and Development of Sustainable Use of Mexican Genetic Resources: Prospects of a SATREPS Project. That would be Science and Technology Research Partnership for Sustainable Development, between the Japanese and Mexican genebanks. Looks like a lot of genotyping and in vitro conservation research on lesser-known crops.
- Establishing the validity of domestication genes using DNA from ancient chickens. You really need ancient DNA to study domestication.
- Genetic diversity and population structure of Mongolian domestic Bactrian camels (Camelus bactrianus). No breeds, no problem.
- Exploring Variability: New Brazilian Varieties SCS119 Rubi and SCS120 Onix for the Specialty Rices Market. Brazilian hipsters now have red and black rice.
Nibbles: Genebanks list, Fish & trees, Indian seed fair, Junk food, Geographic indications, NZ & Canadian heirloom seeds

- Prospects for forest-based ecosystem services in forest-coffee mosaics as forest loss continues in southwestern Ethiopia. Coffee agroforests provide about half to two thirds of the ecosystem services of plain old forests.
- Social Process of Adaptation to Environmental Changes: How Eastern African Societies Intervene between Crops and Climate. Your seeds may not be able to cut it in the future.
- Bioavailability of iron, zinc, and provitamin A carotenoids in biofortified staple crops. Focus on breeding varieties with elevated micronutrient concentrations is justified. Phew.
- The future of warm-season, tropical and subtropical forage legumes in sustainable pastures and rangelands. Those who cannot remember the past are condemned to repeat it. And the past, in this case, was full of mistakes.
- Wild leafy vegetable use and knowledge across multiple sites in Morocco: a case study for transmission of local knowledge? The Rif Mts are a hotspot of weed diversity. Not that kind of weed, settle down. No, wait…
- Agricultural Trade, Biodiversity Effects and Food Price Volatility. Pests are damaging to neat economic models. Pesticides fix that but damage the environment. No word on the economics of natural enemies, integrated pest management, varietal diversity etc.
- Annual burning drives plant communities in remnant grassland ecological networks in an afforested landscape. In the southern Afromontane region, annual burning does not reduce the species diversity of grassland patches, but does make these patches look more and more alike. Add heavy cattle grazing though and that does reduce diversity.
- Responses to fire differ between South African and North American grassland communities. Decreasing fire frequency increased species diversity in Kansas, decreased it in Kwa-Zulu Natal. It’s because of the rhizomatous species in America. What does this and above mean for crop wild relatives?
- Prolonging the longevity of ex situ conserved seeds by storage under anoxia. Remove oxygen to make seeds last longer in genebanks.
- Identification of Sources of Bacterial Wilt Resistance in Common Beans (Phaseolus vulgaris L.). Only 1 resistant accession out of 500 in the USDA collection. And it’s a wild one.
- Evaluation of Evolution and Diversity of Maize Open-Pollinated Varieties Cultivated under Contrasted Environmental and Farmers’ Selection Pressures: A Phenotypical Approach. OPVs are diverse and change over time. Still no cure for cancer.
- A novel allele of the P-starvation tolerance gene OsPSTOL1 from African rice (Oryza glaberrima Steud) and its distribution in the genus Oryza. Kasalath comes to the rescue of NERICA. Must be the only sativa gene NOT in NERICA.
- Agronomic potential of genebank landrace elite accessions for common bean genetic breeding. Yeah, but are they in the Brazilian genebank? Doesn’t look like it.
