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.
Brainfood: African tea, Iranian olives, Persistent identifiers, Fast breeding, Lablab domestication, Pea origin, Celebs & conservation, Ancient dope, Sugarcane evolution, Chicken selection
- Multiple origins and a narrow genepool characterise the African tea germplasm: concordant patterns revealed by nuclear and plastid DNA markers. It’s a “potpourri,” but kinda missing Chinese Assam stuff.
- The eastern part of the Fertile Crescent concealed an unexpected route of olive (Olea europaea L.) differentiation. It was in Iran before domestication.
- Identifiers for the 21st century: How to design, provision, and reuse persistent identifiers to maximize utility and impact of life science data. Why DOIs succeeded, and why something like them needs to be applied to biological specimens, including genebank accessions, to combat “desultory citation practices”. But we knew that.
- Speed breeding: a powerful tool to accelerate crop research and breeding. Can double the number of generations per unit time with fully-enclosed controlled-environment growth chambers.
- Evidence for two domestication events of hyacinth bean (Lablab purpureus (L.) Sweet): a comparative analysis of population genetic data. With the 2-seeded group domesticated in Ethiopia, the 4-seeded somewhere else in Africa.
- Refinement of the collection of wild peas (Pisum L.) and search for the area of pea domestication with a deletion in the plastidic psbA-trnH spacer. Maybe not Turkey.

African chickens able to withstand high temperatures due to a region on chromosome 27 and European chickens low temperatures due to region on chromosome 2.
