Genebank opportunity in the UK

The John Innes Centre has an exciting manager vacancy for its Germplasm Resource Unit (GRU). This facility houses materials essential for the injection of new genetic diversity into crop breeding programmes and the identification of genes controlling key traits.

Interested? You can find out more about the genebank on the JIC website. The data in WIEWS is a little bit out of date, but it gives an overview that’s difficult to get from the genebank’s webpage. The overview page on Genesys has more up-to-date information, but it seems only for wheat, barley and pea.

Anyway, I suppose this means that our friend Mike Ambrose, currently the genebank manager, is retiring. We’ll miss you, Mike.

Brainfood: Soil biodiversity maps, VIR wheat, Rice worlds, African maize, Cold rice, Saharan history, Oil palm & CC, GM Cavendish

Assessing soil biodiversity potentials in Europe. The hotspots are the pastures and grasslands of Ireland, Slovenia and Sweden.
Into the vault of the Vavilov wheats: old diversity for new alleles. VIR has diversity that’s not in CIMMYT and Australian cultivars. No word on where ICARDA fits in.
Disembedding grain: Golden Rice, the Green Revolution, and heirloom seeds in the Philippines. There are parallel and competing rice worlds, which differ in how they valorize the local. Or, it could be argued, though not by the authors, demonize the “other.”
Microsatellite DNA marker for molecular characterization of African maize (Zea mays L.) landraces. The Somali material is weird.
Genetic architecture of cold tolerance in rice (Oryza sativa) determined through high resolution genome-wide analysis. 42 QTLs. Is that a lot? It seems like a lot.
Humans as Agents in the Termination of the African Humid Period. Damn livestock. Back to hunting and gathering.
Future climate effects on suitability for growth of oil palms in Malaysia and Indonesia. Well that’s ironic.
Golden bananas in the field: elevated fruit pro-vitamin A from the expression of a single banana transgene. Gene from Fe’i biofortifies Cavendish. Now to do something about taste, texture, general suckiness etc etc.

Brainfood: Silk Road herders, Canadian erosion, Trees & ag, Wheat CWR, Maize adaptation, Stock collections, Tunisian barley, Seed testing, Rosaceae evolution, MRCA, Deforestation

Nomadic ecology shaped the highland geography of Asia’s Silk Roads. Goat Roads doesn’t have the same ring to it.
Agro-biodiversity has increased over a 95 year period at sub-regional and regional scales in southern Quebec, Canada. It’s all in the definition.
Trees for life: The ecosystem service contribution of trees to food production and livelihoods in the tropics. Meta-analysis shows trees and forests are good for crop yields and livelihoods.
Discovery and characterization of two new stem rust resistance genes in Aegilops sharonensis. Chipping away at Ug99.
A study of allelic diversity underlying flowering-time adaptation in maize landraces. That’s a lot of genes.
The challenges faced by living stock collections in the USA. Money, mainly.
Low Genetic Differentiation and Evidence of Gene Flow among Barley Landrace Populations in Tunisia. One big happy family.
Rethinking the approach to viability monitoring in seed genebanks. From germination tests to automated seed storage experiments.
Evolution of Rosaceae Fruit Types Based on Nuclear Phylogeny in the Context of Geological Times and Genome Duplication. A story of whole genome duplications.
Reconstructing the genome of the most recent common ancestor of flowering plants. The mother of all crop wild relatives, before all those duplications, has 23,000 genes and is 214 million years old.
What Drives Deforestation and What Stops It? A Meta-Analysis. Money, and money, respectively.

DOI guidelines are open for comment

The Secretariat of the International Treaty is pleased to invite Contracting Parties and Stakeholders to provide comments for the update of the Guidelines for the optimal use of Digital Object Identifiers as permanent unique identifiers for germplasm samples – v.2 (herewith attached) elaborated within the Programme of Work on the Global Information System (GLIS) of Article 17.

We talked about this. Now go crazy.

Vegetable life on Mars

“Much to our surprise, despite the soil’s high salinity, two of the 75 potato breeds we had brought in were able to produce tubers in this soil. It was inspiring news to all of us,” Dr. Valdivia-Silva said.

That would be Martian soil. No word on whether the results will make their way into the relevant databases.
