Ca2+ Waves and Ethylene/JA Crosstalk Orchestrate Wound Responses in Arabidopsis Roots

ABSTRACT: Wounding triggers complex and multi-faceted responses in plants. Among these, calcium (Ca²⁺) waves serve as an immediate and localized response to strong stimuli, such as nematode infection or laser ablation. Here, we investigate the propagation patterns of Ca²⁺ waves induced by laser ablation and observe that glutamate-receptor-like channels (GLR3.3/GLR3.6), the stretch-activated anion channel MSL10, and the mechanosensitive Ca²⁺-permeable channels MCA1/MCA2 influence this process. These channels contribute to ethylene-associated signaling pathways, potentially through the WRKY33-ACS6 regulatory network. Furthermore, our findings show that ACC/ethylene signaling modulates Ca²⁺ wave propagation following laser ablation. Ethylene perception and synthesis at the site of damage regulate the l
