- 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”.
Mexican maize biodiversity documented
Via El Cuexcomate, news that CONABIO now has information on the maize races of Mexico on its website, including photos and distribution maps. It’s all part of a huge project to document native maize diversity (including the wild relatives) which was stimulated by fears ((So whether justified or not, at least it cannot be denied that these fears had one positive outcome.)) about the influx of GM maize. And since we’re on the subject of maize, today also saw an informative post on pellagra, complete with very dramatic illustrations.
Sudanese sorghum by the numbers
The Plant Genetic Resources Unit of the Agricultural Research Corporation (ARC) of Sudan has just published a catalog of its sorghum collection. It mainly contains reams of characterization data, which of course will be easier to explore in their digital form, but it’s always good to have illustrations to go with the numbers. Would be great to see the data eventually make their way to Genesys.
Nibbles: Pollinator book, Museums, Quinoa and celiac disease, Plant growth analysis, Mangroves, Plant health
- You’ve heard of alternative lifestyles? Now read all about alternative pollinators.
- Why should we spend money digitizing natural history collections?
- Not all quinoa cultivars may be good for celiacs.
- The largest comparative growth experiment ever. Hope some of the 600+ species are crop wild relatives.
- Mangroves trap heavy metals. And sequester a lot of carbon. But they are moving. Thank goodness there’s lots of ways to value the services they provide.
- CABI’s Plantwise Knowledge Bank is online.
- Kew boffins blow up coffee. The genus, settle down.
Tenerife diversity illustrated
The Centro de Conservación de la Biodiversidad Agrícola de Tenerife (CCBAT) has a Facebook page on which they have just announced the release of an attractive new poster of bean diversity, reproduced here. There’s also one about potatoes. And a book summarizing traditional diversity in all the crops.
