Enhanced metabolic detoxification is associated with fluroxypyr resistance in Bassia scoparia [PDF]

Plant Direct, 2023
Auxin‐mimic herbicides chemically mimic the phytohormone indole‐3‐acetic‐acid (IAA). Within the auxin‐mimic herbicide class, the herbicide fluroxypyr has been extensively used to control kochia (Bassia scoparia).

Fluroxypyr Inhibits Maize Growth by Disturbing the Diversity of the Endophytic Bacterial Communities in Maize Roots [PDF]

Microorganisms
Fluroxypyr (4-amino-3,5-dichloro-6-fluoro-2-pyridyloxyacetic acid) is a widely used herbicide sprayed on crops worldwide. The effects of fluroxypyr on maize growth and the soil microbial community structure have not been reported.

A deletion upstream of the degron of AcIAA27 leads to auxinic herbicide resistance in Arctotheca calendula. [PDF]

Pest Manag Sci
An in‐frame deletion was identified in AcIAA27, compared to the susceptible population, which confer resistance to both 2,4‐D and dicamba. Abstract BACKGROUND Two populations of Arctotheca calendula (capeweed) from near Naracoorte, South Australia, were not controlled by 2,4‐D. These populations were investigated for resistance to 2,4‐D and other auxin

Cytotoxicity Mechanisms of Eight Major Herbicide Active Ingredients in Comparison to Their Commercial Formulations [PDF]

Toxics, 2022
Commercial pesticide formulations contain co-formulants, which are generally considered as having no toxic effects in mammals. This study aims to compare the toxicity of 8 major herbicide active ingredients–namely glyphosate, dicamba, 2,4-D, fluroxypyr ...

A point mutation in IAA34 confers resistance to the auxin herbicide 2,4-D in Sisymbrium orientale. [PDF]

Pest Manag Sci
A point mutation in domain IV of SoAux/IAA34‐R provides resistance to 2,4‐D. Abstract BACKGROUND Sisymbrium orientale has evolved resistance to 2,4‐D in Australia due to a 27 bp deletion in SoIAA2. However, one population of Sisymbrium orientale resistant to 2,4‐D (R1) did not contain the SoIAA2Δ27, suggesting another 2,4‐D resistance mechanism was ...

Identification, characterization, and expression of Oryza sativa tryptophan decarboxylase genes associated with fluroxypyr-meptyl metabolism. [PDF]

Plant Genome
Abstract Tryptophan decarboxylase (TDC) belongs to a family of aromatic amino acid decarboxylases and catalyzes the conversion of tryptophan to tryptamine. It is the enzyme involved in the first step of melatonin (MT) biosynthesis and mediates several key functions in abiotic stress tolerance.

A novel mutation in SoIAA20 confers cross-resistance to 2,4-Dichlorophenoxyacetic acid and other auxinic herbicides in Sonchus oleraceus. [PDF]

Pest Manag Sci
Several populations of Sonchus oleraceus were found to be highly resistant to 2,4‐Dichlorophenoxyacetic acid (2,4‐D), with cross‐resistance to other auxinic herbicides. The resistant populations all contained three amino acid deletions on either side of the highly conserved degron of SoIAA20, whereas the susceptible populations did not.
