|a Essential oils (EOs) from Lavandula angustifolia are known for high commercial value, mainly consisting of monoterpenoids and sesquiterpenoids. Treatment with methyl jasmonate (MeJA) affects the biosynthesis of terpenoids, but the genetic mechanisms remain largely unknown. In this study, the blooming lavender was exposed to 8 mM MeJA for 12 h and a transcriptome was constructed from eighteen samples of lavender. The results showed that MeJA treatment can affect the transcript abundance of genes in biosynthetic pathway. Among glandular trichome, sepal and leaf tissues, the genes related to terpenoid biosynthesis were more responsive to MeJA in the leaf than in the other tissues tested. The use of MeJA had a significant impact on gene expression associated with metabolic pathways, particularly phenylalanine metabolism, plant-pathogen interaction, environmental adaptation, transcription factors, cytochrome P450 and terpenoid backbone biosynthesis. The results of co-expression network analysis showed that transcription factors such as bHLH, MYB and ERF probably play a key role in the biosynthesis of terpenoids. Various stress treatments and analysis of a potential transcription factor LabHLH74 demonstrated that this gene reacts to a variety of environmental stressors. D-limonene levels were also increased in LabHLH74-overexpressing plants. This research will open the door to deciphering the transcription regulatory network about the biosynthesis of volatile terpenoids, and LabHLH74 may be a candidate gene for the development of high-limonene plants
