| Description |
We built the first reference full-length transcriptome of postharvest jasmine flowers, which had 366,081 nonredundant isoforms. Among them, 280,326 (76.57%) were annotated at least one hit in NT, NR, Swissprot, KEGG, KOG, Pfam, and GO databases. Combined with second-generation transcriptome analysis, we identified that 52 differentially expressed transcripts (DETs) involved in terpenoid metabolic pathway, 28 DETs involved in phenylpropanoid/benzenoids metabolic pathway, and 31 β-glucosidase transcripts may relate to aroma formation of postharvest jasmine during flowering. In addition, the expression of 42 heat shock protein (HSP) transcripts were identified that had positively correlated with the content of 11 key odorants by using weighted gene co-expression network analysis (WGCNA). The results described herein advance the knowledge of the regulatory mechanism of aroma formation of postharvest jasmine during flowering, and provide an abundant genetic resource for further studies on gene discovery in jasmine. |
