4-Hydroxyphenylpyruvate dioxygenase is an iron-tyrosinate protein.

Journal of Biological Chemistry, 1986
A resonance Raman investigation into the blue chromophore of 4-hydroxyphenylpyruvate dioxygenase, a non-heme iron enzyme from Pseudomonas P. J. 874, reveals the presence of enhanced vibrations characteristic of tyrosinate coordination to the iron center. The excitation profiles for these features show that they are associated with the 595 nm absorption

Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench). Research was conducted in 2023 and 2024 to evaluate grain sorghum tolerance and weed control from preemergence applications of ...

Effectiveness of bicyclopyrone alone and in combination with hexazinone for controlling Paspalum maritimum Trind. in pre- and post-emergence

Pesquisa Agropecuária Tropical
Ginger grass (Paspalum maritimum Trind.) is a perennial grass that is difficult to control due to the robustness of its rhizome system. This study aimed to evaluate the effectiveness of the bicyclopyrone herbicide in managing this species under ...

DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

Plant, Cell &Environment, Volume 49, Issue 8, Page 5477-5496, August 2026.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

Inheritance of Mesotrione Resistance in an Amaranthus tuberculatus (var. rudis) Population from Nebraska, USA

Frontiers in Plant Science, 2018
A population of Amaranthus tuberculatus (var. rudis) evolved resistance to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicides (mesotrione, tembotrione, and topramezone) in Nebraska.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, Volume 82, Issue 7, Page 6387-6398, July 2026.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

The Inhibitory Activity of Plants from Central Argentina on p-Hydroxyphenylpyruvate Dioxygenase: Isolation and Mechanism of Inhibition of a Flavanone from Flourensia oolepis [PDF]

, 2015
The enzyme 4-hydroxyphenylpyruvate dioxygenase catalyzes the second step in the tyrosine degradation pathway. In mammals, this enzyme is the molecular target of drugs used for the treatment of metabolic disorders associated with defects in the tyrosine ...

Expression of a Cytochrome P450 Gene from Bermuda Grass Cynodon dactylon in Soybean Confers Tolerance to Multiple Herbicides

Plants, 2022
Bermuda grass (Cynodon dactylon) is notoriously difficult to control with some commonly used herbicides. We cloned a cytochrome P450 gene from Bermuda grass, named P450-N-Z1, which was found to confer tolerance to multiple herbicides in transgenic ...

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.
