Preliminary assessment of the effect of waterseeding technique and herbicide application on weedy rice tillers [PDF]

, 2009
Metsulfuron methyl has been recommended to control weedy rice under wetseeded conditions (Zainal and Azmi, unpubl. data, 1994). Another weed control method involves broadcasting pregerminated seeds using the water-seeding technique.

Domestication as innovation : the entanglement of techniques, technology and chance in the domestication of cereal crops [PDF]

, 2010
The origins of agriculture involved pathways of domestication in which human behaviours and plant genetic adaptations were entangled. These changes resulted in consequences that were unintended at the start of the process.

Assessing Physiological and Genetic Evidence for Evolution of Shared Weedy Rice Traits at the Vegetative Growth Stage

Frontiers in Agronomy, 2021
Weedy rice (Oryza spp.) has successfully adapted to invasion of cultivated rice (O. sativa L.) fields by being a strong competitor from the early vegetative growth stages to crop harvest.

Timing is everything: early degradation of abscission layer is associated with increased seed shattering in U.S. weedy rice

BMC Plant Biology, 2011
Background Seed shattering, or shedding, is an important fitness trait for wild and weedy grasses. U.S. weedy rice (Oryza sativa) is a highly shattering weed, thought to have evolved from non-shattering cultivated ancestors. All U.S.

Something old, something new: Evolution of Colombian weedy rice (Oryza spp.) through de novo de‐domestication, exotic gene flow, and hybridization

Evolutionary Applications, 2020
Weedy rice (Oryza spp.) is a worldwide weed of domesticated rice (O. sativa), considered particularly problematic due to its strong competition with the crop, which leads to reduction in yields and harvest quality.

Phenotype Comparison between Herbicide Tolerant Transgenic Rice and Weedy Rice [PDF]

Weed & Turfgrass Science, 2013
The phenotypic traits of herbicide-tolerant transgenic rice were compared with those of wild type (Dongjin) as well as two accessions (Hwaseong-aengmi 1 and Gwangyang-aengmi 12) of weedy rice. This study was conducted to investigate whether unintentional alterations in phenotypic characteristics occurred in the transgenic rice and whether the altered ...

Molecular evolution of the rice blast resistance gene Pi-ta in invasive weedy rice in the USA. [PDF]

PLoS ONE, 2011
The Pi-ta gene in rice has been effectively used to control rice blast disease caused by Magnaporthe oryzae worldwide. Despite a number of studies that reported the Pi-ta gene in domesticated rice and wild species, little is known about how the Pi-ta ...
