^aThe chloroplast genome sequence of Cucumis sativus 'Chipper' line (GenBank Acc. No. DQ865976.1) was used for the comparison
¹Positions where the C. melo sequence has a gap in comparison to cucumber
²Relative to the cucumber genome length
³Positions where the C. sativus sequence has a gap in comparison to melon
⁴Relative to the melon genome length
⁵Cucumber → melon
⁶Highly divergent regions found between the melons at coordinates 126,000 and 130,000
