    Plant Electrophysiological Parameters Represent Leaf Intracellular Water–Nutrient Metabolism and Immunoregulations in <i>Brassica rapa</i> During <i>Plasmodiophora</i> Infection by Antong Xia, Yanyou Wu, Kun Zhai, Dongshan Xiang, Lin Li, Zhanghui Qin, Gratien Twagirayezu

    Published 2025-07-01
    “…Typically, based on distribution of B-type dielectric substance transfer percentage (BPn), we found PWB4 (8 × 10<sup>9</sup> spores/mL) was the maximal immune response concentration, as evidenced by a maximal BPn<sub>R</sub> (B-type dielectric substance transfer percentage based on resistance), with increasing lignin and cork deposition to enhance immunity, and a minimum BPn<sub>Xc</sub> (B-type dielectric substance transfer percentage based on capacitive reactance), with a decreasing quantity of surface proteins in the <i>B. rapa</i> leaves. This study suggests plant electrophysiological parameters could characterize intracellular water–nutrient metabolism and immunoregulation of <i>B. rapa</i> leaves under various <i>Plasmodiophora</i> infection concentrations, offering a dynamic detection method for agricultural disease management.…”
