20.500.12556/DiRROS-21124 Genomic insight into the origin, domestication, dispersal, diversification and human selection of Tartary buckwheat Background: Tartary buckwheat, Fagopyrum tataricum, is a pseudocereal crop with worldwide distribution and high nutritional value. However, the origin and domestication history of this crop remain to be elucidated. Results: Here, by analyzing the population genomics of 567 accessions collected worldwide and reviewing historical documents, we find that Tartary buckwheat originated in the Himalayan region and then spread southwest possibly along with the migration of the Yi people, a minority in Southwestern China that has a long history of planting Tartary buckwheat. Along with the expansion of the Mongol Empire, Tartary buckwheat dispersed to Europe and ultimately to the rest of the world. The different natural growth environments resulted in adaptation, especially significant differences in salt tolerance between northern and southern Chinese Tartary buckwheat populations. By scanning for selective sweeps and using a genome-wide association study, we identify genes responsible for Tartary buckwheat domestication and differentiation, which we then experimentally validate. Comparative genomics and QTL analysis further shed light on the genetic foundation of the easily dehulled trait in a particular variety that was artificially selected by the Wa people, a minority group in Southwestern China known for cultivating Tartary buckwheat specifically for steaming as a staple food to prevent lysine deficiency. Conclusions: This study provides both comprehensive insights into the origin and domestication of, and a foundation for molecular breeding for, Tartary buckwheat. domestication migration artificial selection buckwheat genomics tatarska ajda Fagopyrum tataricum populacijska genomika akcesije molekularna genetika žlahtnjenje rastlin domestifikacija true false true Angleški jezik Slovenski jezik Neznano 2024-12-31 12:24:58 2024-12-31 12:24:58 2025-11-07 12:57:36 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 7. 3. 2024; 24 str. art. 61 Vol. 25 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-04-27 577.2 1474-760X 10.1186/s13059-024-03203-z 188067843 https://genomebiology.biomedcentral.com/articles/10.1186/s13059-024-03203-z 1 df6c2d66-c769-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29948 RAZ_He_Yuqi_2024.pdf RAZ_He_Yuqi_2024.pdf 1 31D3F0336FB068C5ABE5BC8F9D8D2E14 eba1fdefdc9445893bbfd640da110ccfa34cbbfa60ecff1839623ca44543e4a5 2ea3e989-c76a-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29949 Kmetijski inštitut Slovenije Inštitut za nutricionistiko 0 0 0
