|a Chinese bayberry (Myrica rubra Sieb. et Zucc.) is a typical fruit tree grown in the hilly region of Southern China. The fruit is sensitive to storage and transportation conditions and presents a major problem in its commercialization. The present study was conducted to investigate the regulation of gene expression involved in plant hormone signaling pathway in the Chinese bayberry with different treatments of heat and 1-methylcyclopene (1-MCP) during postharvest storage. In one treatment group (HM group), we exposed Chinese bayberry fruit to 48 °C for 10 min and then sealed them in a desiccator with 5 μl·L-1 of 1-MCP for 24 h at 20 °C, followed by storage at 10 °C. Another group (CK group) was directly stored at 10 °C without any prior treatment. Samples of fruit were collected every three days, at 3, 6, 9, 12 and 15 d (CK3, CK6, CK9, CK12 and CK15; and HM3, HM6, HM9, HM12, and HM15, respectively). The decay index of fruits in the CK group increased after six days of storage but did not increase until nine days of storage in the HM group. Superoxide dismutase (SOD) activity in the CK group was shown a downtrend during storage, and almost no fluctuation from six days. In the HM group, SOD activity increased after three days, but decreased sharply after six days storage. Besides, peroxidase (POD) and catalase (CAT) activities were shown the similar trend during the storage, both of them first increased and then decreased form the six days of storage. These physiological data indicated that the sixth day is a crucial time during the storage of Chinese bayberry treated with heat and 1-MCP. Therefore, the transcriptome libraries were constructed from CK0, CK6, HM6 group, respectively. The analysis of top 20 KEGG pathways showed that most differentially expressed genes were involved in the biosynthesis of secondary metabolites, particularly flavonoids and flavanols biosynthesis, in CK0 vs. CK6 and CK0 vs. HM6. However, the top three KEGG pathways in CK6 vs. HM6 were the ribosome, RNA transport and endocytosis during the storage. Expression of six ethylene receptor (ETR) genes and four ethylene-responsive transcription factor (ERF) genes were activated at transcriptional level during the postharvest stage and were decreased by heat and 1-MCP treatment, and serine/threonine-protein kinase 1 (CTR1) was also repressed by treatment. Abscisic acid (ABA) -responsive element binding factor (ABF) gene, auxin-responsive GH3 gene and transcription factor MYC2 gene also showed similar expression pattern with ethylene pathway genes. These results might improve our understanding of the mechanisms of heat and 1-MCP inhibition of fruit postharvest physiology and prolongation of fruit shelf life
