A Comprehensive Molecular Modeling Study of Phenyltriazolinone Derivatives as Protoporphyrinogen Oxidase (PPO) Inhibitors

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
An integrated computational strategy (QSAR, docking, molecular dynamics, and PBSA) identified novel phenyltriazolinone‐based PPO inhibitors with enhanced predicted activity. Compound P7 emerged as the most promising candidate, while P4 and P5 also outperformed sulfentrazone.

Butafenacil: A positive control for identifying anemia- and variegate porphyria-inducing chemicals

Toxicology Reports, 2015
Butafenacil is an herbicide that inhibits protoporphyrinogen oxidase (PPOX), an enzyme that catalyzes oxidation of protoporphyrinogen IX to protoporphyrin IX during chlorophyll and heme biosynthesis.

Molecular Targeted Suppression of Male Fertility in Amaranthus palmeri S. Watson: Function and Layered Double Hydroxide Nanosheets‐Based Delivery System of ApmiR319

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3296-3307, May 2026.
ABSTRACT Amaranthus palmeri is one of the most troublesome invasive agricultural weeds worldwide, exhibiting super invasiveness and high resistance to conventional management strategies. Artificial microRNA‐mediated silencing technology, coupled with a nanoparticle‐mediated delivery system, represents an attractive approach for fertility control in A ...

A Trp574Leu Target-Site Mutation Confers Imazamox Resistance in Multiple Herbicide-Resistant Wild Poinsettia Populations from Brazil

Agronomy, 2020
Wild poinsettia (Euphorbia heterophylla L.) is an important weed species in southern Brazil, especially due to the evolution of multiple herbicide resistance (e.g., acetolactate synthase (ALS)- inhibitors, protoporphyrinogen oxidase inhibitors, and ...

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells

Reproduction in Domestic Animals, Volume 61, Issue 4, April 2026.
ABSTRACT Linuron, chloridazon and metribuzin are herbicides thought to have potential endocrine disruption (ED) effects. This study investigated the effects of linuron, chloridazon and metribuzin on bovine granulosa cell viability and oestrogen (E2) and progesterone (P4) secretion in vitro.

Transcriptome and metabolome reprogramming in tomato plants by Trichoderma harzianum strain T22 primes and enhances defence responses against aphids [PDF]

, 2019
Beneficial fungi in the genus Trichoderma are among the most widespread biocontrol agents of plant pathogens. Their role in triggering plant defences against pathogens has been intensely investigated, while, in contrast, very limited information is ...

Purification and Properties of Protoporphyrinogen Oxidase from Spinach Chloroplasts [PDF]

Plant and Cell Physiology, 2000
Protoporphyrinogen oxidase (Protox), an enzyme that catalyzes the common step of chlorophyll and heme biosynthetic pathways, was purified from spinach chloroplasts. The molecular weight of purified protein was estimated to be approximately 60,000 by SDS-PAGE. Protox activity was stimulated by addition of FAD, suggesting that chloroplast Protox requires

Synthesis and Biological Profile of Substituted Pyrrolidinyl Carboxamides for Acyl‐ACP Thioesterase Inhibition

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...

Physiological and transcriptomic evidence for a close coupling between chloroplast ontogeny and cell cycle progression in the pennate diatom Seminavis robusta [PDF]

, 2008
Despite the growing interest in diatom genomics, detailed time series of gene expression in relation to key cellular processes are still lacking. Here, we investigated the relationships between the cell cycle and chloroplast development in the pennate ...
