    Siderophores are specialized iron-chelating molecules produced by microorganisms to enhance iron acquisition, a critical adaptation for survival in iron-limited environments. This study investigates catecholate-type siderophores synthesized by Bacillus amyloliquefaciens D5, emphasizing their role in sequestering ferric iron and eliciting plant defense responses.Siderophore production was confirmed using CAS-agar and Arnow tests, followed by purification via ion-exchange chromatography. Application of these siderophores to mungbean plants demonstrated concentration-dependent effects on enzymatic activities and total phenolic content. Moreover, siderophore treatment induced the upregulation of defenserelated genes associated with the jasmonic acid/ethylene (JA/ET) pathway, thereby enhancing systemic resistance against Cercospora canescens. These findings underscore siderophores as potent elicitors in agricultural strategies aimed at augmenting plant disease resistance mechanisms.
