Integrated Transcriptomic and Metabolomic Analysis Reveals Biochar-Induced Enhancement of Growth and Secondary Metabolism in the Medicinal Plant <i>Echinacea purpurea</i>.

ABSTRACT: Echinacea purpurea (L.) Moench is a medicinally valuable plant with well-documented pharmacological properties; however, its physiological and molecular responses to biochar amendment remain largely unexplored. This study applied integrated transcriptomic and metabolomic approaches to investigate the underlying mechanisms of biochar-induced effects in E. purpurea. Biochar amendment significantly promoted plant growth and improved nutrient status. Concurrent transcriptomic analysis revealed the molecular basis for these changes, identifying 4733 differentially expressed genes (DEGs). Further analysis showed significant enrichment in plant hormone signal transduction pathways, particularly those of auxin and jasmonic acid (JA). The activation of the JA pathway was specifically
