Plant, Cell &Environment, EarlyView.ABSTRACT Hydroxycinnamic acid amides (HCAAs) are phenylpropanoid‐derived metabolites traditionally associated with antimicrobial defence and cell wall reinforcement during plant–pathogen interactions. However, their contribution to plant responses to mechanical injury, particularly in wound healing and damage‐induced signalling, remains poorly ...

Mechanism and regulation of Arabidopsis polyamine acetylation by NATA1 and NATA2
Protein Science, Volume 35, Issue 12, December 2026.Abstract Polyamines are crucial for sustaining plant growth and stress resilience. Spermine/spermidine N1‐acetyl transferases (SSATs) regulate polyamine abundance by catalyzing their N‐acetylation, thereby reducing the pool of polyamines and producing other bioactive components.
