Integration of transcriptomics and metabolomics provides insights into secondary cell wall deposition and terpenoid biosynthesis during stem development in Camphora officinarum.

ABSTRACT: Camphora officinarum Nees (Cinnamomum camphora) has traditionally been cultivated as bushes for essential oil extraction from its leaves and twigs (small stems). terpenoid deposition in leaves is well-studied, While the stems have received less attention. Using the camphor tree reference genome, we profiled stem transcriptomes and metabolomes across four developmental stages in linalool- and borneol-type camphor trees to elucidate key genes underlying secondary cell wall deposition and terpenoid biosynthesis. Weighted Gene Co-expression Network Analysis (WGCNA) highlighted enrichment of phenylpropanoid and starch and sucrose metabolism pathways, consistent with active secondary cell wall formation. Expression of the full complement of lignin biosynthesis genes, including those participatin
