Lesion Information for Marker:
      Linkage Group of nit-4: IVR
      Markers Left of nit-4: pyr-1 (1 to 6%)
      Markers Right ofnit-4: pan-1 (6 to 27%)
Marker description or requirements:
      IVR. Right of pyr-1 (1 to 6%). Probably right of col-4(2%). Left of pan-1 (6 to 27%) (1000, PB). (94) Cannot use nitrate or nitrite as a nitrogen source, but uses ammonia and amino acids (94). Regulator for induction by nitrate of nitrate reductase and nitrite reductase (1080). Allele nr15, called nit-5 (1000), is phenotypically identical to other nit-4 alleles; shown to be allelic by failure to complement or recombine (0 prototrophs per 2,080 progeny) (1080). Original allele was discovered in a wild isolate of N. intermedia from Borneo and introgressed into N. crassa (94).
