A restriction map of the Cucumis melo L. (melon) plastome was constructed by using several mapping approaches: single and double digestions of the chloroplast DNA (chlDNA) with endonucleases (XhoI, SmaI, SacI and PvuII) and hybridization to heterologous chlDNA probes and to isolated melon chlDNA fragments. Four plastome-coded genes were located using heterologous probes. The overall organization and gene position of the melon plastome was found to be similar to that of tobacco and other angiosperm species. Restriction patterns based on digestion of the chlDNA with nine endonucleases were obtained in over 20 wild species and cultivated varieties of Cucumis. These led to mutational analysis of the restiction sites yielding the most parsimonious phylogenetic tree of the Cucumis plastome. Most African species from a compact group ("Anguria group") which is distant from the melon, the cucumber and a few other species (C. sagittatus, C. metuliferus and C. humifructus). All of these are also far apart from each other. The distribution of polymorphic restriction sites along the Cucumis plastome is described and conservative regions as well as "hot spots" are suggested.
