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 …

Weedy rice refers to the unwanted plants of the genus Oryza that have some undesirable
agronomic traits and pose a major threat to sustainable rice production worldwide …

The use of herbicide-resistant (HR) Clearfield rice (Oryza sativa) to control weedy rice has
increased in the past 12 years to constitute about 60% of rice acreage in Arkansas, where …

Much of agriculture-related research today involves weed resistance to herbicides.
Resistance evolution is perhaps the strongest driver for the quest for new herbicide targets …

There are two species of cultivated rice in the world—Oryza sativa L. from Asia and Oryza
glaberrima Steud. from Africa. The former was domesticated from the wild progenitor Oryza …

Studies were conducted to determine the impact of introgression of crop alleles into weedy
rice populations. Seeds of 89 weedy rice accessions collected from Arkansas fields in 11 …
