Linkage Data for Group V Markers in Neurospora.

paper presents linkage data from crosses with markers in linkage group Ty", Neurospora cicrssa (Group E of HOULAHAN, BEADLE and CALHOUN 1949). Several new markers are reported, and the map relations of a number of other genes are clarified. Many of these data were obtained in the course of an investigation of interference ( STRICKLAND unpublished). Certain of the new markers are in positions where they should be useful for bracketing regions of special interest (e.g., spray, which was first mapped in the present study, has already been employed in investigations of recombination at the complex am locus (PATEMAN 1958)). A total of at least 17 gene loci are now known to belong to group V. These are listed, with references, in Table 1.
