- Evaluation of thermal, chemical, and mechanical seed scarification methods for 4 Great Basin lupine species. They all need different things.
- Exploring novel genetic sources of salinity tolerance in rice through molecular and physiological characterization. A lot of salt-tolerant Bangladeshi landraces cluster together in an aromatic group close to japonica.
- No loss of genetic diversity in the exploited and recently collapsed population of Bay of Biscay anchovy (Engraulis encrasicolus L.). Effective population size has remained steady, irrespective of census population size.
- Molecular characterization of accessions of a rare genetic resource: sugary cassava (Manihot esculenta Crantz) from Brazilian Amazon. Two distinct genetic groups.
- Presence of vetches (Vicia spp.) in agricultural and wild floras of ancient Europe. One of the proto-IndoEuropean roots for the collective name of these things translates as “avoid”.
- Salt tolerance in wild relatives of adzuki bean, Vigna angularis (Willd.) Ohwi et Ohashi. Two crossable wild relatives had different salt tolerance mechanisms.
- The ‘Botanical Gardens of the Dispossessed’ revisited: richness and significance of Old World crops grown by Suriname Maroons. Some crops are only used in rituals now. But even that’s pretty cool, and better than nothing.
- The AVRDC–The World Vegetable Center mungbean (Vigna radiata) core and mini core collections. 1481 (20% of total) accessions chosen by geography and phenotype, then 289 by SSRs.
- Sequencing wild and cultivated cassava and related species reveals extensive interspecific hybridization and genetic diversity. And you can also use the results for rubber!
Nibbles: Deforestation, Mint patent, Weed footprint, Heirloom breeds & vars, Superfood hype latest
- If we eat more meat, only 15% of possible scenarios lead to a maintenance of forest area.
- Oregon mint breeders ready to come to blows.
- The dark side of yesterday’s sustainable ganja Nibble.
- The Smithsonian does heirlooms.
- Enough with the superfoods already.
Brainfood: Bean drought, Tree ranges, Lao rice landrace, Japanese wheat core, Japanese rice quality, Brassica diversity, Prosopis variety, Teff diversity, Agroecosystem diversity & resilience, Grassland spp adaptation
- Physiological traits associated with drought resistance in Andean and Mesoamerican genotypes of common bean (Phaseolus vulgaris L.). Maybe more common in the Mesoamerican genepool, and associated with pod harvest index.
- Estimating potential range and hence climatic adaptability in selected tree species. It’s better if you have trial results.
- Genetic diversity and population structure of ‘Khao Kai Noi’, a Lao rice (Oryza sativa L.) landrace, revealed by microsatellite DNA markers. More variation between than within accessions of same landrace, three genetic groups, and a possible origin in Vietnam.
- Characterization of a mini core collection of Japanese wheat varieties using single-nucleotide polymorphisms generated by genotyping-by-sequencing. Core collection of 96 accessions based on passport and pedigree data turns out to reflect geography and breeding history.
- Variation in cooking and eating quality traits in Japanese rice germplasm accessions. Mainly down to one gene.
- Population genomic analysis reveals differential evolutionary histories and patterns of diversity across subgenomes and subpopulations of Brassica napus L. Spring (SP), winter Europe (WE), and winter Asia (WA) groups, enriched genetic diversity within the WA group, different geographic origins for the C (WE) and A (WA) subgenomes.
- Molecular markers to distinguish ‘Thar Shoba’, a variety of khejri [Prosopis cineraria (L.) Druce], from trees in natural populations. Since the thing has a great morphological marker in being spineless, I don’t really see the point of going all molecular on it, but anyway.
- Assessment of the genetic relationship of tef (Eragrostis tef) genotypes using SSR markers. Molecular markers confirm distinctness of agronomically distinct varieties.
- Linkage between crop diversity and agro-ecosystem resilience: Nonmonotonic agricultural response under alternate regimes. Crop diversity increases productivity during normal conditions, decreases it in adverse conditions, increases the likelihood of staving off an adverse regime.
- Genetic differentiation and regional adaptation among seed origins used for grassland restoration: lessons from a multispecies transplant experiment. Local is best. At least in Germany.
Brainfood: African greens, Latin American pigs, Japanese fruits, Cassava selection, Sunflower breeding, Angolan vegetables, Californian backyard maize, Mesoamerican priorities, Genetic stocks
- Molecular Markers for Genetic Diversity Studies in African Leafy Vegetables. Not surprisingly, only 3% of 33 studies since 1998 are on Cleome, more than half on cowpea. And a quarter used RAPDs. Orphan crops, anyone? These one don’t even get a table summarizing and comparing findings across species.
- Conservation priorities of Iberoamerican pig breeds and their ancestors based on microsatellite information. Depending on how you crunch the genetic numbers, Iberoamerican pig breeds could conceivably best be looked after by conserving their ancestral Iberian pig breeds. But it’s not just about the genetics, is it?
- Native fruit tree genetic resources in Japan. Only a Castanea was domesticated in pre-modern times, and they’re all endangered in post-modern times.
- Perceptual selection and the unconscious selection of ‘volunteer’ seedlings in clonally propagated crops: an example with African cassava (Manihot esculenta Crantz) using ethnobotany and population genetics. It’s seedlings that look most like existing varieties that farmers try to keep.
- Changes in sunflower breeding over the last fifty years. From yield under optimal conditions to disease resistance, from oil quantity to quality. But international collaboration still needed.
- Angolan vegetable crops have unique genotypes of potential value for future breeding programmes. Unique material documented, and hopefully made available for use.
- Maize Germplasm Conservation in Southern California’s Urban Gardens: Introduced Diversity Beyond ex situ and in situ Management. Migrants bring along their crops.
- An assessment of the conservation status of Mesoamerican crop species and their wild relatives in light of climate change. Priority areas for on farm and in situ conservation don’t by and large coincide with protected areas.
- A Proposal Regarding Best Practices for Validating the Identity of Genetic Stocks and the Effects of Genetic Variants. Just do it.
Nibbles: Chinese genebanks, Rough times at Roughwood, EU seed laws, Cacao & coffee migrations, CIMMYT pix
- China’s largest genebank just got a little bit larger. And some context.
- Small Pennsylvania genebank may get a lot smaller.
- Denmark shows the way on seed saving in Europe.
- Chocolate really got around.
- Coffee didn’t do too badly either. But home is where the heart is.
