  • a Gene names are derived from the definition given in the second column. The organism in which the gene has been identified is listed in the third column. In many instances, the gene name is used in more than one species, in many fungi, or in many biological systems. Many gene names represent families of genes in which the gene name is followed by a number which designates a specific gene from the family. For references, see the text.
