Locus	Cultural Requirements	Link Group	Type
un-2	IR. Between the T(AR173) left breakpoint and T(AR190); hence, right of the centromere and arg-3 (1 to 2%) and left of his-2 (1%). Included in duplications from T(AR173) but not from T(AR190) (808). (482). Unknown function. Heat sensitive (482). Growth at 25°C but not at 39°C. Scorable but leaky at 34°C. Formerly called un(46006).	IR	B
thi-4	III. Linked to acr-2, spg, and sc (< 1%). Left of pro-1(3%) and ace-2 (4 to 9%) (812). (482). Requires thiamine (301). Anomalous in condensation of the pyrimidine and thiazole precursors. Very leaky (301). A probable allele called "thi-lo" greatly increases the thiamine requirement of thi-1 strains and decreases the ability to synthesize thiamine from pyrimidine and thiazole. thi-lo strains have no detectable nutritional requirement in the absence of thi-1. thi-lo failed to recombine with thi-4 among 55 scorable progeny (301).
