Genes

Locus	Cultural Requirements	Link Group	Type
cl	VR. Right of pk (<1 %, 2%) (296, 1007). Spreading flat colonies, forming dense bands. Noncircadian periodicity. Mycelium becomes increasingly dense until growth ceases in all but a few hyphae, which reinitiate the cycle. Grows 1 cm per day. Band size and period modifiable. Photographs (296, 1046). Asci from cl x wild type crosses are normal. Homozygous cl x cl crosses (with backcrossed derivatives) give flaccid asci with unordered ascospores similar to those from pk x pkcrosses. cl x pkcrosses do also, suggesting allelism (1007). pk (bis) mutants sometimes form growth bands (296). However, substantial crossing-over frequencies and the recovery of pk cl double mutants (296) indicate that pk and clare at separate loci. Increased activity of L-glutamine:D-fructose-6-phosphate amidotransferase was found in crude extracts of cl and five other morphological mutants (899).	VR	B
