Lavender Gene Expression and Terpene Volatile Data for Plant Defense Research

Three genes from Lavandula angustifolia—LaTPS7, LaTPS8, and LaCYP71D582—were cloned and characterized for their role in producing defense-related volatiles during early plant development. In-vitro assays identified specific compounds produced, including camphene, myrcene, limonene, α-pinene, and sylvestrene. The research, led by Ling Zheng at the Chinese Academy of Sciences, demonstrates how these volatiles repel aphids and attract ladybugs, suggesting agricultural applications for reducing insecticide use.

Use Cases

• Modeling terpene biosynthesis pathways based on gene expression patterns described in the study.
• Training classifiers to predict plant defense responses based on volatile organic compound profiles.
• Analyzing correlations between specific gene activity (e.g., LaTPS7) and production of repellent compounds like limonene.
• Investigating ecological interactions by linking volatile emissions (e.g., α-pinene) to predator-prey behavior data.

Strengths

• Identifies three specific genes (LaTPS7, LaTPS8, LaCYP71D582) and their enzymatic products.
• Describes assays quantifying eight compounds from LaTPS7 and nine from LaTPS8.
• Includes behavioral data showing volatiles repel aphids (Myzus persicae) and attract ladybugs (Harmonia axyridis).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect a specific experimental bias inherent to paperswithcode platform entries.
