Wounding Triggers Multi-Layered Leaf Barriers via Hormones

Wounding Triggers Multi-Layered Leaf Barriers via Hormones

In an illuminating breakthrough in plant biology, researchers have unveiled a sophisticated wound healing mechanism in mature leaves of Arabidopsis that challenges previous understandings of how plants respond to physical damage. While the plant epidermis is already known to serve as a vital protective interface against environmental stressors, the intricate processes by which breaches to this outer layer are repaired—especially in mature tissue…
