Transcriptional Regulation in Leaves of Cut Chrysanthemum (Chrysanthemum morifolium) ‘FenDante’ in Response to Post-Harvest Ethylene Treatment

The early wilting and yellowing of leaves in response to ethylene is the main limitation affecting vase quality cut chrysanthemums. Therefore, leaf senescence most difficult problem post-harvest production Nevertheless, molecular mechanism on regulation chrysanthemum still unclear. In this study, we identified an ethylene-sensitive ‘FenDante,’ which showed rapid chlorophyll content decrease under treatment, resulting before flower senescence. A new generation Illumina sequencing platform was used identify differentially expressed genes treatment chrysanthemum. total 1.04 Gb raw reads obtained, including 753 2790 at 3 h 24 after respectively. KEGG analysis revealed that are mainly involved plant hormone synthesis signal transduction, metabolism, aquaporins, reactive oxygen species. gene expression regulatory networks chrysanthemums were studied, lays foundation for future research mechanisms ethylene-mediated
