The Crystal Structures of Zea mays and Arabidopsis 4-Hydroxyphenylpyruvate Dioxygenase [PDF]

Plant Physiology, 2004
Abstract The transformation of 4-hydroxyphenylpyruvate to homogentisate, catalyzed by 4-hydroxyphenylpyruvate dioxygenase (HPPD), plays an important role in degrading aromatic amino acids. As the reaction product homogentisate serves as aromatic precursor for prenylquinone synthesis in plants, the enzyme is an interesting target for ...

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.

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 ...

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

Assessment of genetically modified soybean DAS‐44406 × FG72 (dossier GMFF‐2025‐34192)

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Genetically modified soybean DAS‐44406‐6 × FG72 was developed by conventional crossing to combine two single events: DAS‐44406‐6 and FG72. The soybean DAS‐44406‐6 × FG72 expresses the AAD‐12, 2mEPSPS, PAT and HPPD W336 proteins to confer herbicide tolerance to 2,4‐D‐, glyphosate‐, glufosinate‐containing and HPPD‐inhibiting herbicide products ...

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 ...

Hepatic‐Differentiated Subpopulation in Clear Cell Renal Cell Carcinoma: A Multi‐Omics Analysis of Tumors With Lymphovascular Invasion

Cancer Medicine, Volume 15, Issue 4, April 2026.
A hepatic‐differentiated subpopulation is associated with lymphovascular invasion in clear cell renal cell carcinoma. A visual summary of the key findings from our multi‐omics analysis. The TITANIA framework enabled the identification of a hepatic‐differentiated ccRCC subpopulation characterized by the upregulation of liver‐like metabolic pathways and ...
