Insights from controlled, comparative experiments highlight the limitations of using BSMV and FoMV for virus‐enabled reverse genetics in rice

Annals of Applied Biology, Volume 188, Issue 3, Page 745-754, May 2026.
Virus‐enabled reverse genetics (VERG) enables transient gene expression modulation in plants but its efficacy varies across species. We evaluated the efficacy of barley stripe mosaic virus (BSMV) and foxtail mosaic virus (FoMV) for virus‐induced gene silencing (VIGS) and virus‐mediated overexpression (VOX) in rice (Oryza sativa).

Competitive N uptake between rice and weedy rice

Field Crops Research, 2006
Abstract Weedy rice, red rice ( Oryza sativa L.), is a serious problem in rice-producing areas of the southern U.S. and various regions worldwide. It competes for production inputs, increases weed control cost, reduces yield and grain quality, and could eliminate economic returns.

Signatures of adaptation in the weedy rice genome

Nature Genetics, 2017
Crop domestication provided the calories that fueled the rise of civilization. For many crop species, domestication was accompanied by the evolution of weedy crop relatives, which aggressively outcompete crops and reduce harvests. Understanding the genetic mechanisms that underlie the evolution of weedy crop relatives is critical for agricultural weed ...

Characterization of lodging variation of weedy rice

Journal of Experimental Botany, 2022
AbstractWeedy rice (Oryza spp.), one of the most notorious weeds of cultivated rice, evades eradication through stem lodging and seed shattering. Many studies have focused on seed shattering, whereas variations in lodging have received less attention and the underlying mechanisms that cause the differences in lodging between weedy and cultivated rice ...

A derived weedy rice × ancestral cultivar cross identifies evolutionarily relevant weediness QTLs

Molecular Ecology, 2023
AbstractWeedy rice (Oryza spp.) is a weedy relative of the cultivated rice that competes with the crop and causes significant production loss. The BHA (blackhull awned) US weedy rice group has evolved from aus cultivated rice and differs from its ancestors in several important weediness traits, including flowering time, plant height and seed shattering.

The origins of weedy rice

Molecular Ecology, 2007
AbstractWhere do weeds come from? How do they evolve from nonweedy ancestors? In this issue of Molecular Ecology, Londo and Schaal examine the origin of weedy rice (Oryza sativa) populations in the USA. Analysing nuclear DNA sequence and microsatellite data, they show the importance of parallel evolution, hybridization, gene flow, and migration in the ...

Competition between Rice and Weedy Rice under Different Water Regimes

Philippine Journal of Science, 2022
The rainfed lowland (RFL) rice ecosystem is prone to drought stress and high weed infestation, including weedy rice (WR), which often negatively affects the yield. This study examined the competitive ability of rice and WR under mixed culture and drought stress.

Evolving insights on weedy rice

Ecological Genetics and Genomics, 2018
Abstract Agricultural weeds that have evolved from de-domesticated (feral) crop plants cause millions of dollars in annual yield losses worldwide and are one of the primary barriers to global crop productivity. Weedy rice (Oryza sativa f. spontanea) is a de-domesticated form of rice that has evolved multiple times independently from different ...
