Quantifying resistance to very-long-chain fatty acid-inhibiting herbicides in Amaranthus tuberculatus using a soilless assay. [PDF]
PLoS ONE, 2023 Resistance to preemergence (PRE) soil-applied herbicides, such as inhibitors of very-long-chain fatty acid (VLCFA) elongases, was documented in two waterhemp [Amaranthus tuberculatus (Moq.) J.D. Sauer] populations (SIR and CHR) from Illinois, USA.

Confirmation of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in New York
Weed TechnologyWaterhemp has become a serious management challenge for field crop growers in New York. Two putative glyphosate-resistant (GR) waterhemp populations (NY1 and NY2) were collected in 2023 from two soybean fields in Seneca County, NY. The objectives of this

Automated approaches for the early stage distinguishing of Palmer amaranth from waterhemp
Frontiers in AgronomyPalmer amaranth and waterhemp are two invasive pigweed species, which have become most troublesome to crops, especially corn and soybean. Among these two weed species, Palmer amaranth is more harmful to crops as it can grow faster, spread rapidly, and ...

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism [PDF]
Plant Direct, Volume 9, Issue 8, August 2025.ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

A molecular cytogenetic perspective on chromosome biology and crop improvement [PDF]
The Plant Genome, Volume 18, Issue 4, December 2025.Abstract The age of molecular cytogenetic analysis of crop plants dawned in the late 1960s and early 1970s with new advances in the identification of somatic chromosomes by C‐banding and fluorescence in situ hybridization concurrent with advances in DNA cloning, sequencing, and mapping. In this perspective article dedicated to Ronald Phillips, I review

Different nontarget‐site mechanisms underlie resistance to dicamba and 2,4‐D in an Amaranthus tuberculatus population [PDF]
Pest Management Science, Volume 81, Issue 7, Page 3464-3473, July 2025.Weak phenotypic and genetic associations between resistance to dicamba and 2,4‐D suggest that different nontarget‐site mechanisms contribute to these traits in an Amaranthus tuberculatus population from Illinois. Abstract BACKGROUND Amaranthus tuberculatus (Moq.) Sauer (waterhemp) has emerged as one of several weed species that is resistant to ...

Comparative analysis of Palmer amaranth (Amaranthus palmeri) and waterhemp (A. tuberculatus) in Iowa [PDF]
, 2021 Waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer), a native to the Midwestern United States, is difficult to control in crops and has become resistant to several herbicides. Emergence and growth of waterhemp have been studied extensively in Iowa. Palmer amaranth (A.
