      Markers Left of nit-6: chol-2 (6%)
      Markers Right ofnit-6: ser-7 (10%) and ad-8(17%)
Marker description or requirements:
      VIL. Right of chol-2 (6%). Left of ser-7 (10%) and ad-8(17%) (PB; O.C. Yoder, personal communication). Unable to use nitrate or nitrite as a nitrogen source (185). Lacks nitrite reductase (185) (Fig. 19), which is subject to positive nitrogen metabolite repression (186). Affected by nit-2 and MS5 regulator genes (838, 1076a) (see nmr-1). Used to study repression of nitrate reductase (26) and nonenzymatic reduction of nitrite (185). Induced by nitrite (198).
