Abstract:
Prestorage exposure to the ethylene-action inhibitor 1-methylcyclopropene (1-MCP) at a concentration of 1 μL L−1 at 20 °C for 24 h significantly retarded peel color change and reduced decay development of cactus pear fruit after 3 weeks of cold storage at 7 °C and 5 days at 20 °C. Exposure to 1-MCP had no significant effects on other fruit-quality attributes, including firmness, weight loss, total soluble solids and acidity levels, and flavor. Exposure to 1-MCP significantly reduced fruit respiration and ethylene production rates. RNA sequencing analysis revealed that 1-MCP mitigated the overall changes in the transcriptome of cactus pear fruit upon cold storage. Functional categorization analysis using the MapMan software revealed that the most pronounced effects of 1-MCP were in averting the massive down-regulation of transcripts belonging to stress, RNA and transcription, signaling and cell categories. Furthermore, exposure to 1-MCP significantly reduced pheophytinase and chlorophyllase transcript levels and increased chitinase transcript levels, thus providing molecular evidence for its observed effects on retardation of peel color change and enhancement of pathogen resistance. In commercial practice, 1-MCP could be applied to cactus pear fruit in order to retard ripening and reduce decay development. © 2017 Institute of Food Science and Technology
