Study of the correlation between endophyte abundances and metabolite levels in different tissue parts of cultivated and wild Arnebia euchroma (Royle) Johnst based on microbiome analysis and metabolomics
Background Arnebia euchroma (Royle) Johnst. has high medicinal and economic value, but in recent years, wild resources of this species have been depleted, and the quality of artificially cultivated A. euchroma has been poor. The endophyte community of medicinal plants is rich, serving as an internal resource that promotes the growth of medicinal plants and the accumulation of secondary metabolites, and has important potential application value in improving the quality of medicinal materials. A. euchroma cultivars and wild varieties contain abundant endophyte communities and metabolites in different tissues. However, the relationships between A. euchroma endophytes and their metabolites in different growth patterns and different tissue sites remain unclear.
