The transcriptional mechanism behind Mimosa pudica leaf folding in response to mechanical disturbance.

ABSTRACT:

Main conclusions

Repeated stress in Mimosa pudica reduces photosystem efficiency, alters gene expression, shifting from flavonoid biosynthesis to stress resistance pathways, offering insights for sustainable plant stress defense strategies. Mimosa pudica is a plant known for its ability to fold leaves in response to mechanical disturbances, which serves as a visible phenotypic stress marker. Leaf folding response occurs with a timing and an intensity that vary depending on the stimulus. This adaptive behavior may function as a defense mechanism, helping plant resist herbivores and environmental stressors. In this study, we investigated the gene regulatory networks underlying M. pudica leaf closure following single and multiple mechanical disturbances (whole pot drops). Chlorophyll
