The most recent complete gene list for Cucurbita species was published in CGC Rpt. 15:102-109 (1992). The following update includes only additions to that gene list and revisions of previous gene symbols. Before publishing a proposed new gene symbol for a Cucurbita species, researchers are urged to consult the gene lists in CGC 15 and CGC 19 in order to avoid using a symbol already assigned to another gene.
