Gene List for Muskmelon (Cucumis melo L.)

Three lists of the genes of Cucumis melo have been published previously (12, 13, 52). Following is a complete and updated list of the 74 known genes of muskmelon. We hope to continue this practice, andpublish a complete list for muskmelon every 3 years.

The names and symbols of two genes were changed: watermelon mosaic virus 1 is now regarded as strain of papaya ringspot virus (49) so Wmv has been changed to Prv. Paris et al. (41) proposed that bush symbolized b be changed to short internode (si) because it is more descriptive of the phenotypic effect of the gene, and because of a second gene that also affects internode length,m si-2. This list includes these proposed changes.

Four additional mutants have been described but not tested for allelism with known mutants of similar phenotypes. three affect leaf characteristics: cut leaf (57), dissected leaves (17) and lobed leaves (19). The fourth is a chlorophyll mutant, flava (42).

It is hoped that scientists will consult the above list as well as the rules of gene nomenclature for the Cucurbitaceae (11, 12, 13, 40) before choosing a gene name and symbol. Thus, inadvertent duplication of gene names and symbols will be prevented. The rules of gene nomenclature were adopted in order to provide guidelines for the naming and symbolizing genes previously reported and those which will be reported in the future. Scientists are urged to contact members of the gene list Committee regarding questions in interpreting the nomenclature rules and in naming and symbolizing new genes.
