Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding

, 2019
: Herbicides of the imidazolinone group have been used in irrigated rice and presented a long persistence in the soil, especially in floodplain areas with a low drainage, and could cause environmental contamination.

Electronic and Steric Tuning of Molecular Acidity toward Unified Models for Excited State Proton Transfer

Advanced Science, Volume 13, Issue 4, 19 January 2026.
Conventional excited‐state proton transfer (ESPT) theories explain the kinetics of fluorescent photoacids, but face challenges for weakly or nonfluorescent ones. This missing link is bridged by making and dissecting series of green fluorescent protein chromophore derivatives with varied photoacidities via strategic substitutions. Structure‐photoacidity

The Bifunctionality of Tetramethylguanidine Enables the Synthesis of Poly Substituted Imidazolinones from Ketones

A novel strategy for the efficient construction of polysubstituted imidazolinones from simple ketones was developed based on the bifunctional role of tetramethylguanidine (TMG).

Systematic characterization of mutations in yeast acetohydroxyacid synthase: Interpretation of herbicide-resistance data

, 2003
Acetohydroxyacid synthase (AHAS, EC 4.1.3.18) catalyses the first step in branched-chain amino acid biosynthesis and is the target for sulfonylurea and imidazolinone herbicides, which act as potent and specific inhibitors. Mutants of the enzyme have been
