Two distinct modes of action of molecular glues in the plant hormone co-receptor COI1-JAZ system.

The plant hormone (3, 7)-jasmonoyl-L-isoleucine ((3, 7)-JA-Ile) is perceived by the COI1-JAZ co-receptor in , leading to the activation of gene expression for plant defense responses, growth, development, and other processes. Therefore, understanding the interaction between the COI1-JAZ co-receptor and its ligands is essential for the development of COI1-JAZ agonists and antagonists as potent chemical tools for regulating (3, 7)-JA-Ile signaling. This study demonstrated that COI1-JAZ has two independent modes of ligand perception using a differential scanning fluorimetry (DSF) assay.

12-Hydroxyjasmonic acid glucoside causes leaf-folding of Samanea saman through ROS accumulation.

Foliar nyctinasty, a circadian rhythmic movement in plants, is common among leguminous plants and has been widely studied. Biological studies on nyctinasty have been conducted using Samanea saman as a model plant. It has been shown that the circadian rhythmic potassium flux from/into motor cells triggers cell shrinking/swelling to cause nyctinastic leaf-folding/opening movement in S.
