Abstract
The colony and sporidial phenotypes of the morphological mutations cauliflower (cf), dull (dl) and modified pseudohyphial (m ph) are described. Tetrad analysis by sporidial sampling of teliospore colonies gave the following centromere-linkage values (cM [centi Morgans]): cf-31.3, dl-15.8, and ph-12.2. The m ph phenotype resulted from a spontaneous mutation in the ph strain. The m and ph mutations are linked (19.3 cM) and are in the same chromosome arm (centromere-ph-m). Excepting teliospores heterozygous for both ph and dl, teliospores from crosses between mutant and wild type strains or between mutant strains gave obviously reduced numbers of teliospore colonies on complex medium.This publication has 2 references indexed in Scilit:
