Figure 3

Inhibition of tomato fruit ripening process by treatment with different substances.

Illustrated are representative pictures of the tomato fruit ripening study. (a) Immature tomato fruits were surface-treated with 200 μM NOP-1, 200 μM AVG and 200 μM MCP, respectively. A control tomato fruit population remained untreated. All NOP-1 treatments led to a delay in fruit ripening of at least 15 days, representing the high inhibitory potential of the synthetic peptide reflecting the EIN2-NLS motif to affect fruit ripening as ethylene response. (b) A related delay in ripening was not observed when fruits were treated with buffer only or treated with random sequence control peptide ROP-1(EFLYMSVN) (adopted from Ref. 26). (c) Green, immature tomato fruits were surface-treated, incubated or injected with 200 μM of NOP-1 as described. Control tomato fruits remained untreated. All applications of NOP-1 led to a delay in fruit ripening of at least 5 days. Delay in maturation process is most evident for fruit surface application.
