Weedy Rice From South Korea Arose From Two Distinct De-domestication Events
Frontiers in Agronomy, 2020 Agro-ecosystems are dominated by crop plants and the weedy species that thrive under agricultural conditions. Weedy crop relatives are some of the most difficult weeds to manage and can dramatically reduce crop yields when left unchecked.

The evolution of flowering strategies in US weedy rice [PDF]
American Journal of Botany, 2014 • Premise of the study: Local adaptation in plants often involves changes in flowering time in response to day length and temperature. Many crops have been selected for uniformity in flowering time. In contrast, variable flowering may be important for increased competitiveness in weed species invading the agricultural environment.
