Brainfood: Mycorrhizal diversity, Olive diversity, Teak diversity, Core software diversity, Cost-benefit, Frosty rye, CGIAR future, Portuguese beans, Improvement networks, Food sovereignty
- Historical biome distribution and recent human disturbance shape the diversity of arbuscular mycorrhizal fungi. Proximity to tropical grasslands during the last glacial maximum makes for a large potential species pool, remoteness from human disturbance for the presence of a high percentage of that pool.
- The First Molecular Identification of an Olive Collection Applying Standard Simple Sequence Repeats and Novel Expressed Sequence Tag Markers. 59 genotypes among 370 trees.
- Worldwide translocation of teak—origin of landraces and present genetic base. The dryer part of the natural range has not really been used in plantations.
- GenoCore: A simple and fast algorithm for core subset selection from large genotype datasets. Better than MSTRAT, Core Hunter, and random sampling.
- Global economic trade-offs between wild nature and tropical agriculture. We can go ahead and cut down the Atlantic Forest. Wait, what?
- Exploring new alleles for frost tolerance in winter rye. Basically one allele, actually.
- Reforming the research policy and impact culture in the CGIAR: Integrating science and systemic capacity development. Let CGIAR be CGIAR.
- Improving global integration of crop research. Taking this to the next level. Which sounded a lot like the International Treaty’s Global Information System on PGRFA. Also, see above.
- Establishing the Bases for Introducing the Unexplored Portuguese Common Bean Germplasm into the Breeding World. 37 accessions had 100% of the diversity of 175 accessions, which were mainly hybrids between the two main genepools. I don’t think I’ve ever seen that before.
- Plant diversity increases with the strength of negative density dependence at the global scale. Janzen-Connell were right, it’s natural enemies that explain the tropical-temperate diversity pattern. With video goodness.
- Local food sovereignty for global food security? Highlighting interplay challenges. “…scaling up of food sovereignty will not necessarily lead to wider sustainability and food security outcomes.”

Brainfood: Kolli Hills diversity, Fergana diversity, Chinese rice terraces, ICRISAT prebreeding, Spanish CWR collecting, Edible flowers, Diversification, Prices vs volatility
- An ethnographic exploration of perceptions of changes in dietary variety in the Kolli Hills, India. Cassava cash cropping has had unforeseen effects on dietary diversity.
- Mapping and assessing crop diversity in the irrigated Fergana Valley, Uzbekistan. More crops on the edges.
- An Analysis on Crops Choice and Its Driving Factors in Agricultural Heritage Systems—A Case of Honghe Hani Rice Terraces System. Established for “red rice”, but that’s not enough.

- A Multispecies Collecting Strategy for Crop Wild Relatives Based on Complementary Areas with a High Density of Ecogeographical Gaps. Collecting in Spain in “…top 10 selected complementary areas would allow the capture of 59 of the 88 targeted taxa and 31% of the 683 different taxa-ELC category combinations identified in the ecogeographical gaps.”

Domesticating horsegram
The indefatigable Dorian Fuller has been even less fatigable than usual lately, with a couple of papers in the past few weeks on the history of the horsegram, Macrotyloma uniflorum. The first is a general review of the geographical, linguistic and archaeological evidence for the origins of the crop. They point to a long history in India and at least two separate domestications there.
The second is a much deeper dive into the history of domestication, using high resolution x-ray computed tomography with a synchrotron to measure non-destructively the decrease in seed coat thickness with time in archaeological remains of domesticated material. A thin seed coat is thought to be related to loss of dormancy, and hence part of the domestication syndrome. It had been suggested that rare non-dormant variants might have been selected during domestication, but the evidence from horsegram is that even the thick-coated, and therefore presumably still dormant, material was domesticated.
Which is all very interesting, but what I want to leave you with is a little quiz. Given that Kersting’s groundnut is now also in Macrotyloma, as M. geocarpum (Harms) Maréchal & Baudet, how many other con-generic species can you think of that were domesticated on separate continents? Apart from the two Oryza species, of course.
