spe-1	VR. Linked to cyh-2 (2%); left of inl (12%) (657, PB). Uses putrescine, spermidine, or spermine. Affects ornithine decarboxylase (L-ornithine carboxy-lyase) (Fig. 10). Does not suppress pro-4 (657). Excretes yellow pigment into synthetic cross medium (PB). Meiosis normal in homozygous crosses (on 50 µg of spermidine per ml), which produce mostly white and a few viable black ascospores (N.B. Raju, personal communication; R. H. Davis, personal communication). Formerly called put-1.	VR
