Spatial metabolomics reveals brassinosteroid-mediated compartmentalization of saikosaponin biosynthesis in Bupleurum chinense DC. under abiotic stress.
Although the biosynthesis of active ingredients in medicinal plants is co-regulated by diverse environmental stimuli, the endocrine mechanism by which brassinosteroids (BRs) coordinate physiological resilience with the in situ spatial distribution of saikosaponins in Bupleurum chinense DC. under combined drought and sa...
