- Is a Cardio-Protective Diet Sustainable? A Review of the Synergies and Tensions Between Foods That Promote the Health of the Heart and the Planet. Yes, but it will take some work.
- Genetic diversity of Malus cultivars and wild relatives in the Chinese National Repository of Apple Germplasm Resources. The varieties from the former Soviet republics and Japan are different to each other and to the canonical European/North American/Chinese material.
- Genetic and phenotypic variation of Turkish Okra (Abelmoschus esculentus L. Moench) accessions and their possible relationship with American, Indian and African germplasms. Turkish okra comes from all over the place.
- DNA barcoding of the main cultivated yams and selected wild species in the genus Dioscorea. 16/21 species I guess is a start.
- Plant responses to climatic extremes: within-species variation equals among-species variation. For a bunch of European grassland plants, within species variation in response to climate was as high as that among species.

- Svalbard among things being discussed at EATx Cali today. Who knows, maybe other genebanks too?
- The cucumber’s wilder relatives.
- Armenian wine going back to the future.
- Whole grains deconstructed.
- Unpicking domestication in chickens and cattle. And the original paper on the latter, featuring the aurochs genome.
- Breeders have bred omega-3 alpha-linolenic acid (ALA) out of soybeans, but are now going back to wild relatives to breed it back in.
That New Yorker story on heirlooms and Luther Burbank
On Friday Luigi nibbled the New Yorker’s recent story What Comes After Heirloom Seeds?, singling out Luther Burbank rather than the more contentious issue of where plant breeding is headed. The New Yorker’s fact-checking is legendary, at least among a certain demographic, in which I number myself. So I want to draw attention to a single punctuation mark, which in my view is imbued with as much snidery as a punctuation mark can be.
Burbank’s prolificacy grew out of a creativity that could seem almost shameless. He was willing to cross just about anything that had leaves: a plum with an apricot (originally a plumcot, now a pluot); a tomato with a potato (a worthless novelty); a blackberry with an apple (no clue); a peach with an almond (!). Burbank’s theoretical validation came from Charles Darwin and his 1876 survey, “The Effects of Cross and Self Fertilisation in the Vegetable Kingdom,” which Burbank seems to have mistaken for a how-to manual. He called himself an “evoluter” of plants.
Can you spot it? Yup, it’s that exclamation mark after the peach X almond cross. At first, I took the whole paragraph to be an expression of the author wilfully showing off his ignorance. After all, the examples seem like pretty obvious crosses to me. So I did a little cursory fact-checking of my own. Seems he’s a gardener. No, wait, he writes about gardening; not the same thing at all.
Why the surprise at peach X almond then? Blowed if I know. So I’ll just science it to death.
Section Amygdalus and section Persicae are closer [to] each other than to any other sections.
What that means is that the peach and the almond were probably the most closely related of the crosses Burbank made, and thus probably the easiest and the least worthy of notice.
The quote is from Phylogeny and Classification of Prunus sensu lato (Rosaceae), by Shuo Shi, Jinlu Li, Jiahui Sun, Jing Yu and Shiliang Zhou, published in the Journal of Integrative Biology (2013) 55: 1069–1079. 1
I’m surprised the New Yorker wasn’t aware of it.
Nibbles: German zucchini, Nice tomatoes, Genebank Database Hell, Pakistan genebank, Brachiaria genomics, Haiti agriculture, Chinese potatoes, Green green grass of home, Domestication book, Rudisha returns!
- Deadly zucchini sweep through Germany. Actually just one possible hybrid with ornamental squash, apparently, probably, I’m told by a vegetables expert.
- Everybody loves photos of heirloom tomatoes.
- Sorting out genebank data management at IRRI.
- It’s very tricky to move the Pakistan national genebank.
- Where are the Al-resistance genes in Brachiaria?
- Le jardin créole in Haiti as a model of sustainable agriculture.
- China’s spud revolution. And more.
- Grass is America’s biggest crop. Tell me something I don’t know. What’s that you say? Not that kind of grass?
- Nice excerpt on cats from recent book on domestication by Richard C. Francis.
- The plant-based diets of East African long-distance runners.
Brainfood: Citrus colours, Soil biodiversity portal, Bean genome, Food diversity & security, French landscape diversity, US pigs, Alien crops, Thai food retail
- Exploring the diversity in Citrus fruit colouration to decipher the relationship between plastid ultrastructure and carotenoid composition. New, weird plastids mean new, weird colours.
- Towards a global platform for linking soil biodiversity data. A DivSeek for soils?
- A reference genome for common bean and genome-wide analysis of dual domestications. Not sure how we missed this. Two domestications confirmed, with distinct genomic signatures.
- Variability of On-Farm Food Plant Diversity and Its Contribution to Food Security: A Case Study of Smallholder Farming Households in Western Kenya. No relationship between farm diversity and food security. Say what?
- What is the plant biodiversity in a cultural landscape? A comparative, multi-scale and interdisciplinary study in olive groves and vineyards (Mediterranean France). Low intensity management with an eye to heritage is good for diversity. But, given the above, so what?
- Relationships among and variation within rare breeds of swine. American pig breeds are real. Mostly.
- Alien Crop Resources and Underutilized Species for Food and Nutritional Security of India. Bring them on!
