摘要：

Key message: Plant defensin AtPDF2.6 is not secreted to the apoplast and localized in cytoplasm. AtPDF2.6 is mainly expressed in root vascular bundles of xylem parenchyma cell, and significantly induced by Cd stress. AtPDF2.6 detoxicate cytoplasmic Cd via chelation, thus enhanced Cd tolerance in Arabidopsis. Abstract: In order to detoxify the heavy metal cadmium (Cd), plants have evolved several mechanisms, among which chelation represents the major Cd-detoxification mechanism. In this study, we aimed to identify a new defensin protein involved...
