Key Points

To characterize the physiological, biochemical, and transcriptomic responses of castor (Ricinus communis L.) exposed to various concentrations of foliar selenium.
Treated castor plants with foliar selenium applications across a concentration gradient, focusing on 20–40 mg/L and a high dose of 60 mg/L.
Assessed antioxidant enzyme activities (SOD, CAT, APX) alongside RNA sequencing to measure transcriptomic changes in hormone signaling and metabolic pathways.
Moderate selenium concentrations (20–40 mg/L) significantly elevated SOD, CAT, and APX activities, activated hormone signaling (JA, SA, auxin, ethylene, ABA), and upregulated phenylpropanoid biosynthesis genes (PAL, CCR, CAD) and transporter families (PHTs, NIPs, ABC).
High selenium exposure (60 mg/L) suppressed antioxidant enzyme activities and downregulated related antioxidant genes, producing physiological stress and toxicity.
