Brainfood: Insurance, Maize roots, Grass strips, Banana nutrients, Fish nutrients, Wild potatoes, Apple genes, Wheat resistance, Killer tomatoes
- Biodiversity as insurance: from concept to measurement and application. It’s important to draw a distinction between the effect of biodiversity on mean and on variance of ecosystem properties.
- Reproductive resilience but not root architecture underpins yield improvement under drought in maize (Zea mays L.). Which presents an opportunity.
- Functional traits driving pollinator and predator responses to newly established grassland strips in agricultural landscapes. Biodiversity takes its time.
- Genetic diversity in fresh fruit pulp mineral profile of 100 Indian Musa accessions. Plenty of diversity, though different micronutrients are correlated, and 100 g contributes only 5-10% of daily mineral requirements.
- Declining diversity of wild-caught species puts dietary nutrient supplies at risk. Let them eat bananas. More nuance.
- A Metric for Species Representation in the US Potato Genebank. Sort of like a core collection, but across species.
- Pyramiding resistance genes and widening the genetic base of the apple (Malus × domestica Borkh.) crop. From 36 cultivars, via 110 cross combinations, to 7,876 offsprings, to 2,969 after screening, to 75 genotypes each with 2-3 of the 20 Rvi6 genes. Hard row to hoe.
- Resistance to diseases in samples of rare wheat species from the N.I. Vavilov All-Russian Institute of Plant Genetic Resources. Very hard row to hoe. Septoria nodorum blotch seems to be particularly tricky.
- Alien introgression and morpho‑agronomic characterization of diploid progenies of Solanum lycopersicoides monosomic alien addition lines (MAALs) toward pre‑breeding applications in tomato (S. lycopersicum). I particularly like the bit where it bursts through John Hurt’s chest.
Genetic diversity to get its place in the sun?
Great to see young guns Sean Hoban and Colin Khoury being interviewed by Emily Henderson on why genetic diversity is important and therefore why — and how — we should save it.
Their latest paper came out last month:
Hoban et al. (2021) Global commitments to conserving genetic diversity are now necessary and feasible. Bioscience doi: 10.1093/biosci/biab054. https://doi.org/10.1093/biosci/biab054
The bottom line?
There must be a CBD post-2020 framework with a clear, measurable, and numerical genetic diversity goal, of the same standing as species and ecosystems, as well as associated action targets…; inclusion and implementation of practical genetic diversity indicators in the CBD and other global biodiversity commitments (e.g., IPBES, SDG); and increased establishment and scaling up of genetic monitoring programs, with those actors having sufficient resources assisting others.
Seconded.
The future of genebanks…
…according to Ruaraidh Sackville Hamilton, lately the genebanks manager at IRRI, that is.
The webinar is tomorrow. But you can also read about his vision, if you’re all zoomed out.
He may or may not say something about cryopreservation. In any case, if you’re into that, there is, of course, another webinar, this one next week.
LATER: Actually he did mention cryo, but much else besides. And you can listen to the whole thing.
