Lesion: sn snowflake
Lesion Information for Marker:
      Linkage Group of sn: IR
      Markers Left of sn: T(39311) and arg-3 (1 to 6%)
      Markers Right ofsn: T(AR173) and his-2 (<1 to 12%)
Marker description or requirements:
      I. Right of T(39311) and arg-3 (1 to 6%). Left of T(AR173) and his-2 (<1 to 12%) (174, 808). (687) Spreading colonial growth with good conidiation. Linear growth is less than 1/10 that of the wild type (19). Detectable immediately after ascospore germination by hyphal patterns which suggested the name (688). Abnormal microfilaments (19). Contains actin-like protein (20). Said not to exhibit cytoplasmic streaming (18). Meiosis and ascospore formation are normal in homozygous sn x sn crosses (N.B. Raju, personal communication). Good female fertility. Morphology similar to that of sp, cum, and cot-4mutants (at 25 C) (PB). Used to study development of crystalline inclusions (17). The cr sn double mutant grows as small, discrete, conidiating colonies suitable for velvet replication. The double mutant cr snresembles the rg cr double mutant phenotypically and has the advantage of fertility in homozygous crosses (796); for example of application, see reference 180.
