wc-1	VIIR. Right of met-9 (1 to 4%). Left of un-10 (7%) and for (6%) (724, 812, 816). Carotenoids absent from mycelia; conidia become pigmented with some delay. Named because nonconidiating rim at top of agar slant remains white. A double mutant with flor other nonconidiating mutant would be classed as albino. Regulatory mutants for photoinduced carotenogenesis via blue light receptor might be expected to have a similar phenotype (444, 445). A blue light treatment (given in vivo), which increases the activity of soluble and microsomal enzymes required for phytoene biosynthesis in the wild type, does not do so in the mutant wc-1 (445). Fails to show phototropism of perithecial beaks when used as the female (protoperithecial) parent, but not when used as the male (fertilizing) parent (R. W. Harding, personal communication). Useful genetic marker (725, 800). Scoring clearest at high temperatures (34 C).	VIIR	B
