I would like to suggest that we do not use "+" or "-" in any nomenclature.
It will be very confusing for genes that are sex-limited in their
expression or those linked to the mating-type loci. For example, the imp-1
mutation is linked to the mt+ locus but under the wrong nomenclature is
might be called imp-1^-.
