- A suite of global accessibility indicators. How long it takes to get from anywhere in the world to settlements of different size. Or took, in 2015.
- A method for computing hourly, historical, terrain‐corrected microclimate anywhere on Earth. Why you might want to move in the first place.
- Genetic strategies for improving crop yields. “Valuable genetic diversity for increasing crop resilience resides in cultivated landraces, heirloom varieties and the wild relatives of crops.”
- A low-cost aeroponic phenotyping system for storage root development: unravelling the below-ground secrets of cassava (Manihot esculenta). But sometimes you have to work hard to get at it: case in point.
- High SNP diversity in the non-toxic indigenous Jatropha curcas germplasm widens the potential of this upcoming major biofuel crop species. And here’s another.
- Genome-wide variation patterns between landraces and cultivars uncover divergent selection during modern wheat breeding. In China and Pakistan anyway.
- Plant populations of three threatened species experience rapid evolution under ex situ cultivation. So don’t cultivate, store seeds instead. Or as well.
- Genes derived from ancient polyploidy have higher genetic diversity and are associated with domestication in Brassica rapa. Polyploidy pre-adapts plants for domestication.
- Genome duplication effects on functional traits and fitness are genetic context and species dependent: studies of synthetic polyploid Fragaria. Case in point.
- A mutualistic interaction between Streptomyces bacteria, strawberry plants and pollinating bees. The rhizosphere protects.
- Do selfing species have greater niche breadth? Support from ecological niche modeling. Yes indeed.
- Modelled distributions and conservation status of the wild relatives of chile peppers (Capsicum L.). 50% are high priority for conservation. No word on their mating systems.
- Construction of a core collection of eggplant (Solanum melongena L.) based on genome-wide SNP and SSR genotypes. From 893 to 100, in 4 geographical clusters.
- A taxonomic monograph of Ipomoea integrated across phylogenetic scales. A whole bunch of new species, and evidence that some 60 species independently developed storage roots before humans were even around. Yes, even sweetpotato.
- Supermarket food purchases and child nutrition in Kenya. Not a bad thing.
USDA … Plant Genetic Resources Conservation Unit located in Griffin, Ga., is home to over 100,000 accessions of preserved plant germplasm including the largest collection of sorghum germplasm in the world.
Well that’s the kind of statement that I just have to fact-check. It’s a little difficult to be entirely sure, Genebank Database Hell being what it is, but I think perhaps the ICRISAT genebank edges it. At least if you go by what’s in Genesys. IND002 is ICRISAT, USA016 the USDA Griffin genebank.
But, of course, it’s not just about the numbers. Only 20% or so of the accessions are geo-referenced, but mapping what data there is does suggest that there are interesting complementarities between the two collections (ICRISAT in red, USDA in blue — click on the map to see it better).
Anyway, do read the rest of the article in Seed World, there’s interesting stuff in there, and what’s a couple thousand sorghum accessions between friends anyway.
A new version of the Musa Germplasm Information System (MGIS) is out. There’s more data, tools for better curation, a way to search for accessions cited in the literature, and re-organized menus. Do check it out. MGIS data eventually makes its way to Genesys.
And since I’m here, it’s worth noting that the banana is uniquely well-endowed with information resources. In addition to MGIS, there’s a whole slew of other databases and assorted information products, thanks to the wonder that is ProMusa.
ProMusa is a network of people promoting scientific discussions on bananas.
In alliance with the International Society for Horticultural Science (ISHS), the network organizes scientific symposia (reported in proceedings) to help its members stay up-to-date on the latest research developments and encourage collaborations within and between disciplines.
When not meeting face-to-face, ProMusa members stay in touch using the network’s mailing list.
This website is the network’s online platform, which offers news, knowledge and information on bananas.
The centrepiece is Musapedia, “an online, collaboratively built compendium of knowledge on bananas.” But there are also databases of scientific literature, images and contacts. And an excellent news area — InfoMus@.
You can follow — and interact with — ProMusa on Facebook and Twitter. I can’t think of a crop that has anything similarly comprehensive. It really should be your first port of call for anything to do with bananas.
