Combined drought and high temperature stress enhances saikosaponin biosynthesis in Bupleurum Chinense through multi-level regulatory mechanisms.

ABSTRACT:

Background

As an important medicinal plant, the synthesis of active ingredient saikosaponin in Bupleurum chinense DC. is significantly influenced by environmental factor stress. However, there is limited understanding of how secondary metabolites in medicinal plants change under the multiple combined stresses.

Results

This study investigated the changes in saikosaponins content in Bupleurum chinense under drought combined with temperature stress, as well as the potential molecular and ecological mechanisms involved. The experimental plants were divided into four groups: control (CK), drought with low temperature (DL), drought with medium temperature (DM), and drought with high temperature (DH). DL, DM, and DH inhibited plant height and root length, with DH exhibiting the str
