Project description:Osmanthus fragrans is an important evergreen species with both medicinal and ornamental value in China. Given the low efficiency of callus proliferation and the difficulty of adventitious bud differentiation, tissue culture and regeneration systems have not been successfully established for this species. To understand the mechanism of callus proliferation, transcriptome sequencing and endogenous hormone content determination were performed from the initial growth stages to the early stages of senescence on O. fragrans calli. In total, 47,340 genes were identified by transcriptome sequencing, including 1798 previously unidentified genes specifically involved in callus development. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of differentially expressed genes (DEGs) was significantly enriched in plant hormone signal transduction pathways. Furthermore, our results from the orthogonal projections to latent structures discrimination analysis (OPLS-DA) of six typical hormones in five development stages of O. fragrans calli showed jasmonic acid (JA) could play important role in the initial stages of calli growth, whereas JA and auxin (IAA) were dominant in the early stages of calli senescence. Based on the weighted gene co-expression network analysis, OfSRC2, OfPP2CD5 and OfARR1, OfPYL3, OfEIL3b were selected as hub genes from the modules with the significant relevance to JA and IAA respectively. The gene regulation network and quantitative real-time PCR implied that during the initial stages of callus growth, the transcription factors (TFs) OfERF4 and OfMYC2a could down-regulate the expression of hub genes OfSRC2 and OfPP2CD5, resulting in decreased JA content and rapid callus growth; during the late stage of callus growth, the TFs OfERF4, OfMYC2a and OfTGA21c, OfHSFA1 could positively regulate the expression of hub genes OfSRC2, OfPP2CD5 and OfARR1, OfPYL3, OfEIL3b, respectively, leading to increased JA and IAA contents and inducing the senescence of O. fragrans calli. Hopefully, our results could provide new insights into the molecular mechanism of the proliferation of O. fragrans calli.
