Papers should be submitted to the respective Coordinating Committee members by 31 December 1991. The report will be published by June 1992. As always, we are eager to hear from CGC members regarding our current activities and the future direction of CGC. Gary W. Elmstrom (muskmelon) J. Brent Loy (Cucurbita spp.) Dennis T. Ray (watermelon) Mark Hutton (other genera) Todd C. Wehner (cucumber) Timothy J. Ng, chair Comments from the CGC Gene List Committee Lists of known genes for the Cucurbitaceae have been published previously in HortScience and in reports of the Cucurbit Genetics Cooperative. GCG is currently publishing complete lists of known genes for cucumber (Cucumis sativus), muskmelon (Cucumis melo), watermelon (Citrullus lanatus), and Cucurbita spp. on a rotating basis. It is hoped that scientists will consult these lists as well as the rules of gene nomenclature for the Cucurbitaceae (see page 140) before selecting 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 of genes previously reported and those that 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.
