spermidine-1

locus: spe-1

locus_name: spermidine-1

organism_type: B

chromosome_number: V

chromosome_side: R

link_group: VR

cultural_requirements: 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.
