Genes

Locus	Cultural Requirements	Link Group	Type
col-4	IVR. Between met-1 (4%) and arg-2 (<1 to 2%) (692, 876, 991). (695) Spreading colonial morphology, forming dense balls of conidia high in slants (47). Probably dominant in heterozygous duplications from T(S1229) (E.G. Barry, personal communication). Cell wall-autolyzing enzyme (631). Reduced amount of cell wall peptides (1165). Used in combination with pe fl to produce microconidiating colonial growth suitable for reversion experiments (386). Called spco-1 (382); called c (386).	IVR	B
pan-1	IVR. Between ad-6 (1 to 2%) and cot-1 (2 to 3%) (633, 692, PB). (482). cel, col-1, int, pho-3, and thi-5 all appear to be closely linked in this crowded region. Requires intact pantothenic acid for growth under standard conditions. Able to synthesize both precursors, beta-alanine and pantoyl lactone (1058). Ability to synthesize pantothenic acid from beta-alanine plus pantoyl lactone is demonstrable in vitro but not in vivo unless cultures are aerated (1111, 1113, 1114). Unlike pan-2, pan-1 has no effect on ascospore ripening in heterozygous crosses. Called group A. For alleles see reference 138.	IVR	B
