Special Issue Information
Dear Colleagues,
Over the years, secondary compounds have been known to be associated with many photochemical processes in forest plants, such as improving the resistance of conifer xylem to insects and fungi, mediating plant responses to biotic or abiotic environmental stresses, and contributing to fruits’ flavor and flower colors. The production and distribution of secondary metabolites are usually specific to plant species, organs, tissues, and growth stages. In many forest trees, the biosynthetic pathways of secondary metabolites are complex and diverse, and the discovery of regulatory genes and enzymes involved in the accumulation of their secondary metabolites is still very limited. Research on improving important biological traits of forest trees through genetic improvement is lagging behind. Therefore, this Special Issue plans to provide an overview of the most recent advances in the discovery and characterization of secondary metabolic pathways in forest trees. This Special Issue is aimed at providing selected contributions on advances in the synthesis, characterization, and applications of secondary metabolites in different forest trees.
Potential topics include, but are not limited to, the following:
- Secondary metabolite biosynthesis of forest trees;
- Mining of gene clusters in biosynthetic pathways;
- Functions of key genes in secondary metabolic pathways;
- Regulatory networks of secondary metabolites;
- Prospects of secondary metabolites in forest trees.

Abstract: Scent is the key character of the horticultural ornamental plant rose, and ben-zenoid-phenylpropanoid compounds are the main source of scent. However, the underlying bi-osynthesis mechanism of these benzenoid-phenylpropanoid scent metabolites during rosa flowering is poorly understand. In this study, we conducted the volatile metabolome and tran-scriptome conjoint analysis to the six stage petals of the variety ‘Lanxing’ to investigate ben-zenoid-phenylpropanoid metabolites synthesis. A total of 25 benzenoid-phenylpropanoid vola-tile compounds were identified, of which eugenol possessed the highest content. Meanwhile, we obtained 87.9 million clean reads and 22,004 differentially expressed genes (DEGs) in transcrip-tome analysis. By combining eugenol content variation trend, spatio-temporal gene expression, kyoto encyclopedia of genes and genomes (KEGG) enrichment, gene ontology (GO) enrichment and phenotype correlation analysis, we found a key candidate gene RcEGS32 related to the eu-genol synthesis. Co-expression network analysis found that five transcription factor RcMYB1, RcBES1, RcERF2, RcbHLH1, and RcTUB may act as regulator in eugenol synthesis process by di-rectly binding to RcEGS32 or form complex unit. Our study provides key insight into the for-mation of the scent substance eugenol during flowering, offering valuable volatile metabolome and transcriptome resource for the future target trait related gene discovery of roses.
