Conclusion
The study assembled a chromosome-level genome of rosemary, demonstrating a high level of genomic integrity in comparison to previously reported genomes (Bornowski et al., 2020). Notably, S. rosmarinus differs significantly from other Salvia species in both of plant morphology and secondary metabolites. To investigate the genetic basis for these differences, our study provides a genomic resource for exploring the structural and genetic basis of monoterpene and diterpenoid accumulation in S. rosmarinus , which will facilitate the development of molecular breeding and quality improvement of this species.
