Early Holocene crop cultivation and landscape modification in Amazonia (Nature)

To date, archeobotanical and genetic studies indicated four centers of plant cultivation in the early Holocene: China and the Near East in the Old World, and southwestern Mexico and northwestern South America in the New World. Recent research of Lombardo et al. revealed that Llanos de Moxos (Bolivia)…

Opinion. Anthropogenic seed dispersal: Rethinking the origins of plant domestication (Trends Plant Sci)

Studies regarding the development of agriculture have started to integrate a plant evolutionary perspective. In this context, Spengler explores how changes in seed dispersal allowed plant domestication during the first half of the Holocene (e.g., more than 5000 years ago). He starts by redefining domestication…

The bracteatus pineapple genome and domestication of clonally propagated crops (OA) (Nature Genetics)

You probably know well the sweet and yellow “smooth cayenne” pineapple (Ananas comosus). This fruit was domesticated a few millennia ago in South America. Pineapple domestication targeted fiber production, color, and sugar accumulation. How it happened remained mysterious. To resolve this mystery,…

Metabolome divergence during maize domestication

Xu et al. identify metabolites targeted by selection during maize domestication. Plant Cell https://doi.org/10.1105/tpc.19.00111 By Guanghui Xu State Key Laboratory of Plant Physiology and Biochemistry, National Maize Improvement Center, Key Laboratory of Biology and Genetic Improvement of…

Yam genomics supports West Africa as a major cradle of crop domestication (Sci Advances)

Yams (Dioscorea spp.) were domesticated independently in three continents. African yam (Dioscorea rotundata) is the second most produced crop in Africa, after cassava but ahead of maize, rice and sorghum. Scarcelli et al. use a genomic approach to learn more about its domestication, by sequencing many…

Domestication of wild tomato is accelerated by genome editing (Nature Biotech. - $)

Wild tomato, Solanum pimpinellifolium, exhibits remarkable tolerance to salt stress and bacterial spot disease. Domestication of S.pimpinellifolium requires adjustment of day-length sensitivity, plant compactness, fruit size and the fruit could benefit from increased vitamin C content. Li et al. used…
