Lesion: pdx-1 pyridoxine-1
Lesion Information for Marker:
      Linkage Group of pdx-1: IVR
      Markers Left of pdx-1: pyr-1 (<1 to 10%)
      Markers Right ofpdx-1: T(S1229) and pt (2%)
Marker description or requirements:
      IVR. Right of pyr-1 (<1 to 10%). Left of T(S1229) and pt (2%) (40, 55, 692, 808). (482) Uses pyridoxine, pyridoxal, or pyridoxamine (843, 845, 846). Shows intralocus complementation (845, 846) and recombination (848), Provided the first proven example of gene conversion (686). Scoring is sharpened by addition of 100 mg of desoxypyridoxine per liter (845). Several alleles (called pdxp: e.g., 44602) are pH sensitive and can grow without pyridoxine on medium containing ammonium ions at a pH above 6 (1029). Conidia are subject to death by unbalanced growth on minimal medium (1033). A yellow pigment is excreted under certain conditions by the pdx-1;En(pdx) double mutant; see En(pdx). Allele 44204 originally called pdx-2 (see reference 848).
