The plant hormone jasmonate (JA) fulfils essential roles in plant defense and development. While most of our current understanding of the JA pathway comes from the dicotyledonous model plant Arabidopsis thaliana, new studies in monocotyledonous plants are providing additional insights into this important hormone signaling pathway. In this review, we present a comparative overview of the JA biosynthetic and signaling pathways in monocots. We highlight recent studies that have revealed molecular mechanisms (mostly conserved but also diverged) underlying JA signaling and biosynthesis in the economically important plants: maize and rice. A better understanding of the JA pathway in monocots should lead to significant improvements in pest and pathogen resistance in cereal crops, which provide the bulk of the world's food and feed supply.
植物激素茉莉酸（JA）在植物防御和发育中发挥着重要作用。虽然我们目前对 JA 途径的大部分了解来自双子叶模式植物拟南芥，但单子叶植物的新研究为这一重要激素信号通路提供了更多的见解。在这篇综述中，我们对单子叶植物的 JA 生物合成和信号通路进行了比较概述。我们强调了最近的研究，这些研究揭示了 JA 信号转导和生物合成的分子机制（大多数保守但也有分歧），这些机制在经济上重要的植物中：玉米和水稻。更好地了解单子叶植物中的 JA 途径应该会显著提高谷类作物对害虫和病原体的抗性，这些作物提供了世界上大部分的食物和饲料供应。
