- First off — a pretty big deal. Taylor & Francis have made a bunch of papers related to sustainable agriculture freely available, but only until the end of December. Happy whatever holiday won’t offend you.
- Twentieth-century changes in the genetic composition of Swedish field pea metapopulations. Metapopulations have become isolated populations. In genebanks.
- Effects of different irrigation systems on the biodiversity of species-rich hay meadows. Change from the traditional irrigation system has affected biodiversity levels, but not a huge amount.
- Research regarding the use of wheat biodiversity for obtaining some cereal-based fermented mashes. Let’s go straight to what we need to know here: the best mash come from spelt wheat. Oh, to be the one doing the organoleptic characterization.
- Cultivation and high capitalization of medicinal and aromatic plants in the Romanian-Bulgarian cross-border region. If you’re really interested, there’s a database that brings it all together.
- Crop biodiversity, productivity and production risk: Panel data micro-evidence from Ethiopia. More crops = more production. But the devil is in the details, I suspect.
- Identification of gaps in pearl millet germplasm from East and Southern Africa conserved at the ICRISAT genebank. We used to do this sort of thing by hand in my day.
- At3g08030 transcript: a molecular marker of seed ageing. This mRNA could predict germination performance of a dry seed lot across species. Good for genebanks?
- Assembling a core collection from the flax world collection maintained by Plant Gene Resources of Canada. You don’t hear much about core collections these days, why is that?
Nibbles: Old rice, New quinoa, Fishy stuff, Cropland landscapes, Forest landscapes, Old seed, Superdomestication, Intensification
- Youth compiles list of rare and extinct rice varieties of Assam. Maybe he should look at weedy rice too?
- Meanwhile, American farmers are learning to grow quinoa, probably including some rare varieties.
- The smelliest fish in the world. No traceability needed for that one, I guess.
- Cropland getting mapped. Presumably including the Globally Important Agricultural Heritage Systems (GIAHS). Help needed by both, by the way.
- Follow the forest discussions at COP18. High on the agenda: what is a landscape? It’s what you study when you’re being holistic, no? Anyway, there’s got to be a connection to the previous links.
- Boffins find a genetic marker for old seed. Will need to Brainfood this one.
- Pat Heslop-Harrison breaks down superdomestication for you.
- SRI gets a scaling up. What could possibly go wrong?
Nibbles: Fungi, Fireblight, Flood Relief, Irrational Ghanaian men, Symposium, Dust Bowl Blues, SRI, Brazil’s agro-policy
- Where do new mushrooms come from? Hint: domestication of wild species has not stopped.
- And resistance to fireblight in apples? Hint: a single specimen of an old variety.
- How about help for flood-stricken Nigerian farmers? Hint: a gene bank!
- Where do people get gender in agriculture all wrong? Hint: women may bring home the bacon, but if that threatens their husband’s status, rationality flies out the door.
- Where, from 10-13 December, can you learn about “Crops from the past and new crops in adressing (sic) the challenges of the XXI century”? Hint: Córdoba, Spain.
- Where did the Dust Bowl go? Hint: it never went away.
- Where to get the straight dope on System of Rice Intensification? Hint: an SRI researcher may not be unbiased.
- Where are government and civil society elaborating a National Plan for Agroecology and Organic Production? Hint: a river runs through it.
Brainfood: Pig genome, Turkey genome, Big genomes, Maize genome, Potato improvement, Mango diversity, Coconut germination
- Analyses of pig genomes provide insight into porcine demography and evolution. More wild diversity in Asia, suggesting origin there, followed by migration to Europe. Separate domestication in SE Asia and Europe, followed by geneflow.
- Whole genome SNP discovery and analysis of genetic diversity in Turkey (Meleagris gallopavo). Lot less diverse than chicken. Or pig. Commercial breed even less diverse.
- Why size really matters when sequencing plant genomes. We must not shy away from the big genomes.
- QTL mapping in three tropical maize populations reveals a set of constitutive and adaptive genomic regions for drought tolerance. Eureka!
- Crops that feed the world 8: Potato: are the trends of increased global production sustainable? Maybe. But can you guess what will be needed? Nice review of genebank holdings and improvement strategies and aims.
- Physico-chemical Characterization of Unexploited Mango Diversity in Sub-mountane Zone of Northern India. 28 varieties in the Punjab, with all kinds of different uses.
- Germination Rate is the Significant Characteristic Determining Coconut Palm Diversity. Natural and artificial selection associated with different rates of germination (as well as other phenotypic traits of course).
It’s germplasm evaluation, Jim, but not as we know it
Next generation sequencing (NGS) holds the promise for a more efficient approach to germplasm evaluation whereby a carefully selected subset of accessions can be sequenced and phenotyped in detail; associations discovered between genotypes and phenotypes in this subset could be used to predict the phenotype of other accessions based on sequence data alone.
Ah, “the promise.” Always the promise. But actually, in this document, “Technical appraisal of strategic approaches to large-scale germplasm evaluation,” some of the practicalities are spelled out, and in quite a lot of detail. You be the judge of whether the vision outlined in that opening quote is of a far-away, Star Trek world, or something that’s really just around the next corner. You can comment on the document itself, or here if you prefer.
