As revealed by the relative accumulation of ACO1 and ERF
transcripts, UV-C treatment affected the expression of most genes
investigated (Fig. 1). There was an increase in the accumulation of
ACO1 gene transcripts when fruits were treated with UV-C
(Fig. 1A), and the application of 1-MCP prior to UV-C treatment
reduced levels of ACO1 transcripts compared to UV-C treatment
alone; however, levels were still above those observed in the
control fruit.
