Transcriptomics and Metabolomics Analyses Reveal Defensive Responses and Flavonoid Biosynthesis of Dracaena cochinchinensis (Lour.) S. C. Chen under Wound Stress in Natural Conditions.

ABSTRACT: Dracaena cochinchinensis has special defensive reactions against wound stress. Under wound stress, D. cochinchinensis generates a resin that is an important medicine known as dragon's blood. However, the molecular mechanism underlying the defensive reactions is unclear. Metabolomics and transcriptomics analyses were performed on stems of D. cochinchinensis at different timepoints from the short term to the long term after wounding. According to the 378 identified compounds, wound-induced secondary metabolic processes exhibited three-phase characteristics: short term (0-5 days), middle term (10 days-3 months), and long term (6-17 months). The wound-induced transcriptome profile exhibited characteristics of four stages: within 24 h, 1-5 days, 10-30 days, and long term. T
