Evolution of imidazolinone-resistant weedy rice in Malaysia: the current status [PDF]
, 2021 Weedy rice (Oryza sativa f. spontanea or O. sativa complex) has become a severe threat to Malaysian rice (Oryza sativa L.) granaries after the direct-seeding method of rice cultivation was introduced in the late 1980s.

Multiple compensatory mutations contribute to the de‐domestication of Iberian weedy rice
Plants, People, Planet, 2022 Societal Impact Statement Weedy plants are a major constraint on agricultural productivity. Weedy rice is a weed that invades rice fields worldwide and is responsible for reductions in rice yields. Studies to date have detected multiple independent weedy

Evolutionary Genomics of Weedy Rice in the USA [PDF]
Journal of Integrative Plant Biology, 2007 AbstractRed rice is an interfertile, weedy form of cultivated rice (Oryza sativa L.) that competes aggressively with the crop in the southern US, reducing yields and contaminating harvests. No wild Oryza species occur in North America and the weed has been proposed to have evolved through multiple mechanisms, including “de‐domestication” of US crop ...

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.

Comparative Metabolomics Analysis of Weedy Rice (Oryza spp.) across Peninsular Malaysia
Agriculture, 2023 Weedy rice (Oryza spp.) is a notorious weed that invades paddy fields and hampers the rice’s production and yield quality; thus, it has become a major problem for rice farmers worldwide. Weedy rice comprises a diverse morphology and phenotypic variation;

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.
