Nano‐selenium foliar intervention‐induced resistance of cucumber to <scp> <i>Botrytis cinerea</i> </scp> by activating jasmonic acid biosynthesis and regulating phenolic acid and cucurbitacin

Abstract

In conclusion, the activation of the phenylpropane biosynthesis and branched-chain fatty acid pathways by Nano-Se promotes the accumulation of jasmonic acid and cucurbitacin in cucumber plants. This enhancement enables the plants to exhibit resistance against B. cinerea infections. Additionally, this study identified a potential candidate gene for cucumber resistance to B. cinerea induced by Nano-Se, thereby laying a theoretical foundation for further research in this area. © 2023 Society of Chemical Industry.
