Plant Defense Priming: ABA and JA Signaling Pathways in Local and Systemic Leaves #2326829 (License: Personal Use)

This scientific illustration depicts the molecular crosstalk between abscisic acid (ABA) and jasmonic acid (JA) pathways during induced defense priming in Arabidopsis. Local leaf damage (site A) initiates signaling that propagates systemically to undamaged leaves (B and C), where MYC2 transcription factor integrates ABA/JA inputs to upregulate the defense marker gene VSP1. The green-shaded leaves indicate systemic response zones, while darker green highlights the locally wounded leaf.

Used in plant biology or molecular botany webpages explaining induced systemic resistance, defense hormone crosstalk, or stress priming mechanisms; targets researchers, students, and educators seeking mechanistic diagrams for teaching or publication support.
