Abstract Greenhouse and laboratory experiments were conducted to investigate mechanisms of glyphosate resistance in horseweed populations from Mississippi, Arkansas, Delaware, and Tennessee. A nondestructive leaf-dip bioassay was developed to confirm resistance and susceptibility in individual test plants. A single leaf was excised from each plant, and the petiole and bottom one-fourth of leaf was dipped in a 600 mg ae L−1 glyphosate solution for 2 d followed by visually estimating the injury… 
SHIKIMATE ACCUMULATION , GLYPHOSATE ABSORPTION AND TRANSLOCATION IN HORSEWEED BIOTYPES
In Brazil, few research works on mechanisms of weed resistance to glyphosate have been conducted so far. Therefore, this research aimed to study analytical procedures determining the relation between
Shikimate accumulation, glyphosate absorption and translocation in horseweed biotypes
TLDR
The procedure for quantification of shikimic acid was suitable for Rand S plants differentiation to glyphosate, indicating that the R population is actually resistant to glyphosate.
Assessment of two nondestructive assays for detecting glyphosate resistance in horseweed (Conyza canadensis)
TLDR
Two rapid, nondestructive assays were developed and tested for their potential in differentiating glyphosate-resistant from glyphosate-susceptible biotypes of horseweed and might have utility for screening other weed populations for resistance to glyphosate.
Assessment of two nondestructive assays for detecting glyphosate resistance in horseweed (Conyza canadensis)
Abstract Two rapid, nondestructive assays were developed and tested for their potential in differentiating glyphosate-resistant from glyphosate-susceptible biotypes of horseweed. In one assay, leaves
Glyphosate translocation in hairy fleabane (Conyza bonariensis)..
The objective of this work was to evaluate the translocation of glyphosate in C. bonariensis plants resistant and susceptible to that herbicide. The C-glyphosate was mixed with commercial gyhphosate
Confirmation, Characterization, and Management of Glyphosate-Resistant Ragweed Parthenium (Parthenium hysterophorus L.) in the Everglades Agricultural Area of South Florida
TLDR
It is shown that absorption or translocation is not a mechanism of glyphosate resistance by ragweed parthenium, and the resistant biotype was 40- to 43-fold less sensitive to glyphosate when compared to the susceptible biotype.
Sourgrass resistance mechanism to the herbicide glyphosate 3 Absorption and translocation of glyphosate in resistant and susceptible biotypes of Digitaria insularis
The knowledge on the mechanism that gives a weed resistance to a particular herbicide is essential regarding scientific, academic, and practical aspects because it determines the recommendations for
Physiological and molecular bases of glyphosate resistance in Conyza bonariensis biotypes from Spain
TLDR
The results suggest that two factors may be related to glyphosate resistance in the R biotypes: impaired translocation and high basal EPSPS transcript levels.

Investigations into glyphosate-resistant horseweed (Conyza canadensis): retention, uptake, translocation, and metabolism
TLDR
The results suggest that resistance is likely due to altered cellular distribution that impaired phloem loading and plastidic import of glyphosate resulting in reduced overall translocation as well as inhibition of EPSPS.
Glyphosate-Resistant Horseweed (Conyza canadensis) in Mississippi1
TLDR
It is demonstrated that the difficult-to-control biotypes were resistant to glyphosate, that resistant biotypes could survive glyphosate rates of up to 6.72 kg/ha, and that plant size affected both resistant and susceptible biotypes in a similar manner.
Shikimate accumulates in both glyphosate-sensitive and glyphosate-resistant horseweed (Conyza canadensis L. Cronq.).
TLDR
This direct comparison conclusively confirms that horseweed plants collected in western Tennessee in 2002 are resistant to 4 times the normal application dosage of glyphosate, implying that alternative control strategies for glyphosate-resistant horseweed will be needed in those no-tillage production systems where it commonly occurs.
RESISTANCE TO GLYPHOSATE IN LOLIUM RIGIDUM. II. UPTAKE, TRANSLOCATION, ANDMETABOLISM

Investigating the mechanism of glyphosate resistance in rigid ryegrass (Lolium ridigum)
Abstract Glyphosate is a broad-spectrum herbicide that has been used extensively for more than 20 yr. The first glyphosate-resistant weed biotype appeared in 1996; it involved a rigid ryegrass
Factors Affecting Toxicity, Absorption, and Translocation of Glyphosate in Redvine (Brunnichia ovata)1
TLDR
Results suggest that longer periods of leaf exposure to the herbicide and high temperatures could increase glyphosate absorption, translocation to redvine rootstocks, and subsequent control, and suggest that effective control of redvine in the field will require glyphosate rates higher than those recommended for use in glyphosate-resistant crops.
Resistance to glyphosate in Lolium rigidum
TLDR
It is speculated that movement of glyphosate to its site of action in the plastid is involved in the resistance mechanism of annual ryegrass populations that have developed resistance to most major herbicides.
A first report of glyphosate‐resistant goosegrass (Eleusine indica (L) Gaertn) in Malaysia
TLDR
In an attempt to rule out environmental and other agronomic factors, and to further quantify the level of resistance, seeds of the ‘Teluk Intan’ biotype was found to be 8- to 12-fold resistant to glyphosate.
Absorption and translocation of glyphosate in Erythroxylum coca and E. novogranatense
TLDR
Differences in absorption and translocation of glyphosate in E. novogranatense may partially explain the reported differential response to glyphosate.
Evolved resistance to glyphosate in rigid ryegrass (Lolium rigidum) in Australia.
TLDR
Following 15 yr of successful use, glyphosate failed to control a population of the widespread grass weed rigid ryegrass in Australia and the presence of glyphosate resistance in a major weed species indicates a need for changes in glyphosate use patterns.
