Inhibition of O-acetylserine (thiol) lyase as a promising new mechanism of action for herbicides.

Enzymes of the sulfur assimilation pathway of plants have been identified as potential targets for herbicide development, given their crucial role in synthesizing amino acids, coenzymes, and various sulfated compounds. In this pathway, O-acetylserine (thiol) lyase (OAS-TL; EC 2.5.

Aluminum oxide nanoparticles affect the cell wall structure and lignin composition slightly altering the soybean growth.

Aluminum oxide (AlO) nanoparticles (NPs) are among the nanoparticles most used industrially, but their impacts on living organisms are widely unknown. We evaluated the effects of 50-1000 mg L AlO NPs on the growth, metabolism of lignin and its monomeric composition in soybean plants. AlO NPs did not affect the length of roots and stems.

Lignin-induced growth inhibition in soybean exposed to iron oxide nanoparticles.

Plants are occasionally exposed to environmental perturbations that limit their growth. One of these perturbations is the exposure to and interaction with various nanoparticles (NPs) that are discarded continuously into the environment. Hitherto, no study has been carried out evaluating the effects of iron oxide (γ-FeO) NPs on soybean growth and lignin formation, as proposed herein.
