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 ...

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.

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;

Salinity effects on germination and growth of Malaysian weedy rice biotypes and cultivated rice [PDF]
, 2016 Germination and seedling growth of plant species are reduced in saline due to an external osmotic potential. An experiment was conducted at the laboratory, Faculty of Sustainable Agriculture, Universiti Malaysia Sabah, to compare the salt effect on seed ...

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 ...
