Transcriptomics and metabolomics analyses provide insights into plant resistance of Alsophila spinulosa

Abstract Background : Tenthredinidae feeds on Alsophila. This study aimed to detect special metabolites that attract pests. Metabolomics and transcriptomics analyses were used on the Alsophila spinulosa and Gymnosphaera metteniana var. subglabra samples. Results : The results of transcriptome changes indicate that differentially expressed genes (degrees) are involved, such as genes expressing kaempferol-3-O-glucoside-7-O-rhamnoside. It has a wide range of expression patterns in plants and may lead to the color and morphology of leaves of the A. spinulosa and G. metteniana var. subglabra. Conclusions : These results are helpful to identify effective biological control methods and provide a scientific basis for maintaining a good habitat for Alsophila spp. in the nature reserve in later stages.
