New markers and map sequences inNeurospora crassa, with a description of mapping by duplication coverage, and of multiple translocation stocks for testing linkage

Thirty previously unmapped markers have been located; 13 are at newly designated loci. Numerous sequences for previously mapped genes have also been determined. A revised map of linkage group I is presented. The order from conventional mapping has been confirmed by testing recessive markers in IL for coverage by duplications. Assignment of new mutants to linkage groups is greatly facilitated by using gene-tagged multiple translocation strains for linkage detection; these “alcoy” tester strains and procedures for using them are described. Recent mapping data of other workers are compiled. Distal markers are now known for all but one of the 14 chromosome arms, but extensive map segments are still devoid of markers.
