Tuber or not tuber

A paper in Cell has really caught the imagination of the media in the past few days. You wouldn’t necessarily be able to guess why from its title, though: “Ancient hybridization underlies tuberization and radiation of the potato lineage.” The reason for all the interest, I guess, is that the hybridization in question was between a potato ancestor with no tubers and a plant that was closer to a tomato. Yes, two genes from distant lineages, neither tuber-forming, combined by chance some 9 million years ago to produce the progenitor of all tuber-bearing potatoes, which then diversified as the Andes were uplifted and themselves diversified. Definitely worth the hoopla.

Jeremy also includes the paper in his latest newsletter.

  1. What has agrobiodiversity ever done for us? Kent Nnadozie of the Plant Treaty lays it out.
  2. Michael Frei of the HealthyDiets4Africa project doesn’t need it laid out.
  3. Neither do the people who awarded a prize to Charlotte Allender of the UK Vegetable Genebank.
  4. What has the US National Plant Germplasm System ever done for anyone? The Guardian, the NY Times and NPR News lay it out. I guess someone in D.C. needs it laid out, but will it make any difference?
  5. Everyone: Potatoes in Florida! Breeders: No problem. NPGS: You called?
  6. Here’s The Guardian again, but this time thinking it is making the case for not putting seeds in the fridge, whereas in fact it’s making the case for the complementarity of ex situ and on-farm conservation.
  7. Speaking of on-farm conservation, here’s a couple of pieces on community seed banks in Guatemala.
  8. Speaking of on-farm conservation, here’s the heart-warming story of Welsh organic farmer Gerald Miles.
  9. Meanwhile, the World Vegetable Centre opens a new genebank.
  10. And Türkiye hosts an international, no less, olive genebank.
  11. And genebanks can be so beautiful, like works of art. Former Tate Modern director Vicente Todolí lays out his citrus samples. I wonder what he could do with olives.
  12. Botanic gardens are beautiful and often act a little bit like crop genebanks. Here’s an example from Portugal I stumbled onto recently, I forget how.
  13. You know what I’d like to see? An international pepper genebank, that’s what. No, not the kind that might be in those Guatemalan community seedbanks or the WorldVeg genebank. This sort of pepper. Piper pepper.
  14. I bet the ancient Egyptians had pepper. Egyptian archaeologist Mennat-Allah El Dorry lays out what else they had.
  15. Maybe you could lay out world history using pepper. You can definitely do so using cacao and chocolate.
  16. No, not using ancient DNA, but actually…
