Transcriptomic analysis of Phoebe bournei twigs and leaves reveals

Phoebe bournei is a potential medicinal plant. Its essential oils (EOs) are mainly composed of sesquiterpenes with inhibitory activities against certain bacteria and tumors. Nutrient enrichment had a certain impact on the composition of the EOs. In the present study the effects of compost and compound fertilizer on the total amount and main components of P. bournei EOs were evaluated, and differentially expressed genes involved in the biosynthesis of sesquiterpenes and in response to fertilization were identified by transcriptome sequencing. Significant differences were found in the number of differentially expressed genes (DEGs) with the leaves showing a greater number of DEGs as compared to the twigs after the compost treatment.
