説明
<jats:title>Abstract</jats:title><jats:p>Jasmonic acid (<jats:styled-content style="fixed-case">JA</jats:styled-content>) is involved in the regulation of host immunity in plants. Recently, we demonstrated that <jats:styled-content style="fixed-case">JA</jats:styled-content> signalling has an important role in resistance to rice bacterial blight caused by <jats:italic><jats:styled-content style="fixed-case">X</jats:styled-content>anthomonas oryzae</jats:italic> pv. <jats:italic>oryzae</jats:italic> (<jats:italic>Xoo</jats:italic>) in rice. Here, we report that many volatile compounds accumulate in response to exogenous application of <jats:styled-content style="fixed-case">JA</jats:styled-content>, including the monoterpene linalool. Expression of <jats:italic>linalool synthase</jats:italic> was up‐regulated by <jats:styled-content style="fixed-case">JA</jats:styled-content>. Vapour treatment with linalool induced resistance to <jats:italic>Xoo</jats:italic>, and transgenic rice plants overexpressing <jats:italic>linalool synthase</jats:italic> were more resistance to <jats:italic>Xoo</jats:italic>, presumably due to the up‐regulation of defence‐related genes in the absence of any treatment. <jats:styled-content style="fixed-case">JA</jats:styled-content>‐induced accumulation of linalool was regulated by <jats:styled-content style="fixed-case">OsJAZ</jats:styled-content>8, a rice jasmonate <jats:styled-content style="fixed-case">ZIM</jats:styled-content>‐domain protein involving the <jats:styled-content style="fixed-case">JA</jats:styled-content> signalling pathway at the transcriptional level, suggesting that linalool plays an important role in <jats:styled-content style="fixed-case">JA</jats:styled-content>‐induced resistance to <jats:italic>Xoo</jats:italic> in rice.</jats:p>
