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

Our findings demonstrate that the synthesis and accumulation of saikosaponins exhibit a "short-term promotional effect" under combined stress, regulated by multiple factors. This study elucidates the molecular and ecological mechanisms underlying the rapid accumulation of saikosaponins and provides technical insights for ecological strategies to support B. chinense high-quality cultivation.
