Response of imidazolinone-resistant and -susceptible weedy rice populations to imazethapyr and increased atmospheric CO2 [PDF]
Planta Daninha, 2020 Background: Weedy rice (Oryza sativa L.) is the main weed of rice crop. The high genetic variability of weedy rice contributes to the high phenotypic diversity between biotypes and different responses to environmental stress.

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.

Genetic Identity Based on Whole-Genome SNP Array Data of Weedy Rice in Nagano, Japan
Agronomy, 2019 The rice production system in Japan is changing due to the aging of rice farmers, shortage of labor, mechanization, and increase of large-scale rice fields and increased application of direct sowing, all of which contribute to the lack of sophisticated ...

QTL Analysis for Resistance to Blast Disease in U.S. Weedy Rice
Molecular Plant-Microbe Interactions, 2015 Understanding the genetic architecture of adaptation is of great importance in evolutionary biology. U.S. weedy rice is well adapted to the local conditions in U.S. rice fields.
