Jasminum sambac(jasmine flower),a world-renowned plant appreciated for its excep-tional flower fragrance,is of cultural and economic importance.However,the genetic basis of its fragrance is largely unknown.Here,we present the first de novo genome assembly of J.sambac with 550.12 Mb(scaffold N50=40.10 Mb)assembled into 13 pseudochromosomes.Terpene synthase(TPS)genes associated with flower fragrance are considerably amplified in the form of gene clusters through tandem duplications in the genome.Gene clusters within the salicylic acid/benzoic acid/theobromine(SABATH)and benzylalcohol O-acetyltransferase/anthocyanin O-hydroxycinnamoyltransferases/anthranilate N-hydroxycinnamoyl/benzoyltransferase/deacetyl-vindoline 4-O-acetyltransferase(BAHD)superfamilies were identified to be related to the biosyn-thesis of phenylpropanoid/benzenoid compounds.Several key genes involved in jasmonate biosyn-thesis were duplicated,causing an increase in copy numbers.In addition,multi-omics analyses identified various aromatic compounds and many genes involved in fragrance biosynthesis path-ways.Furthermore,the roles of JsTPS3 in β-ocimene biosynthesis,as well as JsAOC1 and JsAOS in jasmonic acid biosynthesis,were functionally validated.The genome assembled in this study for J.sambac offers a basic genetic resource for studying floral scent and jasmonate biosynthesis,and provides a foundation for functional genomic research and variety improvements in Jasminum.
