Fig. 6.

Expression of MaNAC and MaEIL genes in banana fruit peel with four different ripening characteristics: natural (control), ethylene-induced, 1-MCP-delayed, and a combination of 1-MCP and ethylene-treated ripening. The expression levels of each gene are expressed as a ratio relative to the harvest time (0 d of control), which was set at 1. Each value represents the mean ±SE of three replicates. The broken arrow and full arrow represent the time point of ethylene production beginning to increase and its peak for each treatment, respectively.
