The medicinal herb coriander ( L.), with a high linalool (LIN) content, is widely recognized for its therapeutic benefits. As a novel report, the goals of this study were to determine how methyl jasmonate (MeJA) affects total phenolic content (TPC), LIN content, flavonoid content (TFC), and changes in gene expression involved in the linalool biosynthesis pathway ( and ). Our findings showed that, in comparison to the control samples, MeJA treatment substantially enhanced the TPC, LIN, and TFC content in both ecotypes. Additionally, for both Iranian coriander ecotypes, treatment-induced increases in and expression were connected to LIN accumulation in all treatments. A 24 h treatment with 150 µM MeJA substantially increased the LIN content in the Mashhad and Zanjan ecotypes, which was between 1.48 and 1.69 times greater than that in untreated plants, according to gas chromatography-mass spectrometry (GC-MS) analysis. Our findings demonstrated that MeJA significantly affects the accumulation of LIN, TPC, and TFC in Iranian treated with MeJA, which is likely the consequence of gene activation from the monoterpene biosynthesis pathway. Our discoveries have improved the understanding of the molecular mechanisms behind LIN synthesis in coriander plants.
药用草本芫荽（L.）因其具有治疗功效而广为人知，其中含有较高含量的芳樟醇（LIN）。作为一项新颖的报告，本研究旨在确定茉莉酸甲酯（MeJA）如何影响总酚含量（TPC）、LIN 含量、类黄酮含量（TFC）以及涉及芳樟醇生物合成途径的基因表达的变化（和）。我们的研究结果表明，与对照样品相比，MeJA 处理可显著提高两种生态型的 TPC、LIN 和 TFC 含量。此外，对于伊朗芫荽的两种生态型，在所有处理中，诱导表达的和与 LIN 积累有关。用 150µM MeJA 处理 24 小时可显著提高马什哈德和赞詹生态型的 LIN 含量，根据气相色谱-质谱（GC-MS）分析，其含量比未处理植物高 1.48 至 1.69 倍。我们的研究结果表明，MeJA 显著影响经 MeJA 处理的伊朗芫荽中 LIN、TPC 和 TFC 的积累，这可能是单萜生物合成途径中基因激活的结果。我们的发现提高了对芫荽植物中 LIN 合成分子机制的理解。
