- Analysis of threats to South American flora and its implications for conservation. Bottom line: Ecuadorian and Colombian Andes, southern Paraguay, the Guyana shield, southern Brazil, and Bolivia. But don’t let that divert your attention from the cool maps.
- Management increases genetic diversity of honey bees via admixture. No genetic bottleneck there. And the same in more words, but not as many as the original paper.
- Phylogeography of Asian wild rice, Oryza rufipogon: a genome-wide view. When in doubt, throw more markers at it. Two groups in O. rufipogon, only the Chinese/Indochinese one related to cultivated rice (indica). Japonica out on a limb. And the longer version.
- Legume Diversity Patterns in West Central Africa: Influence of Species Biology on Distribution Models. Temperature variables are most important.
- Multiple domestications of the Mesoamerican gene pool of lima bean (Phaseolus lunatus L.): evidence from chloroplast DNA sequences. Andean and Mesoamerican cultivated genepools confirmed, and two sub-genepools within the latter, one originating in western central Mexico and the other between Guatemala and Costa Rica. Will they mash up with the study in the first link? Some of the people involved are neighbours and friends.
Brainfood: Wild soybean, Leafy vegetables collection gaps, Banana drought tolerance screening, Chinese soybean breeding, Malagasy coffee collections, Bacteria on beans
- Perennial Glycine: A new source of genetic diversity for soybean improvement. The perennial wild species are genetically and geographically distant from the crop, but at least one can be crossed, with some difficulty, and some potentially useful genes have been enticed to make their way into the cultivated genome. To no great effect, but it’s early days yet.
- Genetic resources collections of leafy vegetables (lettuce, spinach, chicory, artichoke, asparagus, lamb’s lettuce, rhubarb and rocket salad): composition and gaps. You can just read the collecting priorities for each genepool, or analyze the data yourself.
- Screening the banana biodiversity for drought tolerance: can an in vitro growth model and proteomics be used as a tool to discover tolerant varieties and understand homeostasis? Maybe.
- Development of yield and some photosynthetic characteristics during 82 years of genetic improvement of soybean genotypes in northeast China. Yield doubled, but at the cost of water use efficiency. Maybe those perennials could help?
- An assessment of the genetic integrity of ex situ germplasm collections of three endangered species of Coffea from Madagascar: implications for the management of field germplasm collections. For 3 wild species, there’s lots of genetic diversity in field genebanks, but also lots of crossing with other species.
- Diversity of culturable bacteria and occurrence of phytopathogenic species in bean seeds (Phaseolus vulgaris L.) preserved in a germplasm bank. “…the fact that potentially phytopathogenic bacteria have been preserved in a genebank should emphasize the importance of rigorous sanitary controls for plant genetic resources.” You think?
Brainfood: Lathyrus sativus, Leafy green porridge, iDArTs, Pungency, Earth ovens, Domestication, Recovery, Maize genomics
- Exploring the genetic diversity of Ethiopian grass pea (Lathyrus sativus L.) using EST-SSR markers. They’re variable, especially in Gonder, and future collecting missions need to give “due attention to underrepresented regions”.
- Green leafy porridges: how good are they in controlling glycaemic response?. Pretty good, but the leafy greens may not be what you’re expecting.
- iDArTs: increasing the value of genomic resources at no cost. No cost for genotyping, that is; the analysis probably does cost.
- A versatile PCR marker for pungency in Capsicum spp. Beats having to taste each progeny plant, I suppose.
- Earth Ovens (Píib) in the Maya Lowlands: Ethnobotanical Data Supporting Early Use. The food preparation method is as old as the food itself; 3400-3000 bce.
- Patterns and processes in crop domestication: an historical review and quantitative analysis of 203 global food crops. Terrific, broad survey, worth more of a write-up.
- Changes in Avian and Plant Communities of Aspen Woodlands over 12 Years after Livestock Removal in the Northwestern Great Basin. Removing livestock leads to “recovery of biological integrity”. Because livestock are not integral to anything.
- Historical genomics of North American maize. Fascinating analysis indicates selection based on a limited set of ancestor lines, and “decreased diversity in the ancestry of individual lines”.
Brainfood: Orange maize, Maize history
- Using a discrete choice experiment to elicit the demand for a nutritious food: Willingness-to-pay for orange maize in rural Zambia. Farmers say they’ll pay, if they have information about nutrition, and it doesn’t matter how you serve that information. Gotta love economics.
- Historical genomics of North American maize. No orange maize here, but clear evidence of decreasing genetic diversity in parental lines.
Brainfood: Cacao, Yak genome, Quinoa production
- The Search for Value and Meaning in the Cocoa Supply Chain in Costa Rica. Organic and Fairtrade are all very well, but watch out for “integration of the story of producers’ commitment and dedication; shared producer and consumer values of social and environmental responsibility; and personal relationships between producers and consumers”.
- The yak genome and adaptation to life at high altitude. Guess what. They’re genetically adapted to high altitude!
- What is Wrong With the Sustainability of Quinoa Production in Southern Bolivia – A Reply to Winkel et al. (2012). One thing that’s wrong is that the link to Winkel et al. is broken. So here it is …
- The Sustainability of Quinoa Production in Southern Bolivia: from Misrepresentations to Questionable Solutions. Comments on Jacobsen (2011, J. Agron. Crop Sci. 197: 390–399). You can make your own way further down the rabbit hole.
