摘要： The development of fungal rots is one of the main limitations of the storage and marketing of sweet cherry fruit. Sweet cherry ( Prunus avium L.) var 'Xiangquan No.1' fruit were treated with 1 g L- 1 5-aminolevulinic acid (5- ALA) hydrochloride and stored at 20 degrees C for 12 d. Results showed that fruit treated with 5-ALA hydrochloride had significantly lowered postharvest decay. Transcriptomic and metabolomic analysis indicated that 1031 differentially accumulated metabolites (DAMs) and 6903 differentially expressed genes (DEGs) were detected between 5-ALA hydrochloride treatment and the control at 6 d. A weighted gene co-correlation network analysis was employed to evaluate the gene regulatory network of DEGs. The DEGs and DAMs were co-enriched in the phenylpropanoid biosynthesis and flavonoid biosynthesis pathways. Moreover, the 5-ALA hydrochloride treatment improved disease resistance of the fruit by activating genes related to salicylic acid signal transduction and down-regulation of the metabolite gibberellin in sweet cherry fruit. The multiple transcription factors, including NAC50, MYB62, LEP and WRKY40 were also activated by 5-ALA hydrochloride treatment. These results provided new ideas for research on the postharvest management and maintenance of sweet cherry fruit during storage.
