Crop–Weed Introgression Plays Critical Roles in Genetic Differentiation and Diversity of Weedy Rice: A Case Study of Human-Influenced Weed Evolution [PDF]

Biology, 2023
As an important driving force, introgression plays an essential role in shaping the evolution of plant species. However, knowledge concerning how introgression affects plant evolution in agroecosystems with strong human influences is still limited.

Weedy (red) rice: an emerging constraint to global rice production

, 2015
Ongoing increases in the human population necessitate that rice will continue to be a critical aspect of food security for the twenty-first century. While production must increase in the coming decades to meet demand, such increases will be accompanied ...

Genomic patterns of nucleotide diversity in divergent populations of U.S. weedy rice [PDF]

BMC Evolutionary Biology, 2010
Background Weedy rice (red rice), a conspecific weed of cultivated rice (Oryza sativa L.), is a significant problem throughout the world and an emerging threat in regions where it was previously absent.

Weedy Rice as a Novel Gene Resource: A Genome-Wide Association Study of Anthocyanin Biosynthesis and an Evaluation of Nutritional Quality [PDF]

Frontiers in Plant Science, 2020
The pericarp color of rice grains is an important agronomic trait affected by domestication, and the color pigment, anthocyanin, is one of the key determinants of rice nutritional quality.

Exploratory survey of rice growing practices identifies perceptions and management of weedy rice [PDF]

California Agriculture
Weedy rice (_Oryza sativa_ L. spp.) is an emerging weed in California rice production. To address weedy rice issues and improve extension efforts, information is needed about the prevalence of growing practices that may contribute to or prevent weedy ...

Gene flow from weedy rice to T1c-19 transgenic rice stacked with cry1C*/bar genes and fitness of F1 hybrids [PDF]

Frontiers in Plant Science
IntroductionBidirectional gene flow via pollen between transgenic rice and weedy rice could occur in natural fields. Gene flow from transgenic rice to weedy rice has been confirmed in many studies, and thus results showed that F1 hybrids could persist in

Comparison of leaf anatomical structure and photosynthetic characteristics between weedy rice and cultivated rice at the seedling stage [PDF]

Scientific Reports
To explore the internal factors related to the strong growth and competitive ability of weedy rice during the seedling period, we collected two biotypes of Japonica weedy rice from Northeast China, four biotypes of Indica weedy rice from Eastern China ...

Reducing Seed Shattering in Weedy Rice by Editing SH4 and qSH1 Genes: Implications in Environmental Biosafety and Weed Control through Transgene Mitigation [PDF]

Biology, 2022
Mitigating the function of acquired transgenes in crop wild/weedy relatives can provide an ideal strategy to reduce the possible undesired environmental impacts of pollen-mediated transgene flow from genetically engineered (GE) crops.

Ser-653-Asn substitution in the acetohydroxyacid synthase gene confers resistance in weedy rice to imidazolinone herbicides in Malaysia. [PDF]

PLoS ONE, 2020
The continuous and sole dependence on imidazolinone (IMI) herbicides for weedy rice control has led to the evolution of herbicide resistance in weedy rice populations across various countries growing IMI herbicide-resistant rice (IMI-rice), including ...
