Lavender essential oils (EOs) are economically valuable, with biosynthesis linked to photosynthesis. NAD(P)H-quinone oxidoreductases (NDHs) play a crucial role in regulating photosynthetic processes. To better understand the functional roles and mechanisms of NDHs, we investigated NDHs (LaNDHs) using AlphaFold2 for structural prediction and RT-qPCR for expression analysis. Gene showed highest expression in leaves compared to other tissues (stems, roots and flowers), with upregulation under cadmium ion, heat, salt, and blue light. These findings suggest LaNDHs enhance stress tolerance and photosynthesis, offering potential for improving EO yield.
薰衣草精油具有经济价值，其生物合成与光合作用相关。NAD(P)H-醌氧化还原酶（NDHs）在调节光合过程中起关键作用。为了更好地了解NDHs的功能作用和机制，我们使用AlphaFold2进行结构预测，并通过RT-qPCR进行表达分析，对NDHs（LaNDHs）展开了研究。与其他组织（茎、根和花）相比，基因在叶片中表达最高，在镉离子、热、盐和蓝光处理下上调。这些发现表明LaNDHs增强了胁迫耐受性和光合作用，为提高精油产量提供了潜力。
