Transcriptomic Analysis Identifies New Non-Target Site Glyphosate-Resistance Genes in Conyza bonariensis

Plants, 2019
Conyza bonariensis (hairy fleabane) is one of the most problematic and widespread glyphosate-resistant weeds in the world. This highly competitive weed species significantly interferes with crop growth and substantially decreases crop yield.

Weed Resistance to Herbicides in Mexico: A Review

Agronomy
Herbicide resistance in weeds has become a critical challenge in worldwide and Mexican agriculture. Many of these cases involve single, cross and multiple resistance to herbicides that inhibit Acetyl CoA Carboxylase (ACCase), Acetolactate Synthase (ALS),

Resistance Mechanisms to Glyphosate in Lamarckia aurea (L.) Moench Found in Southern Spain

Agronomy
Glyphosate has been used for roadside weed control in southern Spain for over 40 years, and most populations of goldentop (Lamarckia aurea L.) Moench have putatively developed resistance to this active ingredient.

The Unsung Champions of Evolution: Weeds and Their Management in Agricultural Systems

Agriculture
The history of weeds is closely intertwined with the development of agriculture. As early farmers began to select crops, weeds emerged as formidable competitors, evolving alongside them in a continuous struggle for survival.

Transcriptome analysis and non-target-site resistance mechanism of multi-resistant Lolium multiflorum under herbicide stress

Current Plant Biology
Lolium multiflorum, one of the most problematic weeds in winter cereal crops, is resistant to herbicidal stress. However, the genome-wide full-length transcripts of L. multiflorum have not been identified, and the mechanism of non-target-site resistance (

Multi-gene metabolic detoxification conferring cyhalofop-butyl resistance in Echinochloa crus-galli (Barnyard grass)

Ecotoxicology and Environmental Safety
With the long-term and widespread application of cyhalofop-butyl in Chinese rice cultivation systems, resistant barnyard grass (Echinochloa crus-galli) populations have been continuously detected and reported, indicating that herbicide resistance has ...

What Is New for the Mechanisms of Plant Resistance to Paraquat After Decades of Research?

Agriculture
Paraquat is one of the most widely used nonselective herbicides globally. Although the emergence of weed resistance to paraquat has progressed relatively slowly since the first reported case in Japan in 1980, it has been steadily increasing.
