Phytosulfokine peptide regulates growth-immunity tradeoff through CAMTA3-mediated transcriptional signaling in Arabidopsis.
A PSK-triggered transcriptional signaling pathway that fine-tunes the tradeoff between growth and immunity in Arabidopsis thaliana is disclosed, uncovers a previously uncharacterized transcriptional regulatory pathway through which PSK orchestrates the balance between plant growth and immunity.
