Adaptation and the Geographic Spread of Crop Species.
Crops are plant species that were domesticated starting about 11,000 years ago from several centers of origin, most prominently the Fertile Crescent, East Asia, and Mesoamerica. From their domestication centers, these crops spread across the globe and had to adapt to differing environments as a result of this dispersal. We...Gutaker, Rafal M. ; Purugganan, Michael D.

Ancient DNA genomics and the renaissance of herbaria.
Herbaria are undergoing a renaissance as valuable sources of genomic data for exploring plant evolution, ecology, and diversity. Ancient DNA retrieved from herbarium specimens can provide unprecedented glimpses into past plant communities, their interactions with biotic and abiotic factors, and the genetic changes that have occurred over time. Here, we...Burbano, Hernán A. ; Gutaker, Rafal M.

Genome analysis traces regional dispersal of rice in Taiwan and Southeast Asia.
The dispersal of rice (Oryza sativa) following domestication influenced massive social and cultural changes across South, East, and Southeast Asia. The history of dispersal across islands of Southeast Asia, and the role of Taiwan and the Austronesian expansion in this process remain largely unresolved. Here, we reconstructed the routes of...Alam, Ornob ; Gutaker, Rafal M. ; Wu, Cheng-chieh ; Hicks, Karen A. ; Bocinsky, Kyle …

Isolation, Library Preparation, and Bioinformatic Analysis of Historical and Ancient Plant DNA
The ability to sequence DNA retrieved from ancient and historical material plays a crucial role in reinforcing evolutionary and anthropological inference. While the focus of the field is largely on analyzing DNA from ancient hominids and other animals, we have also learned from plant ancient DNA (aDNA), in particular, about...
