Locus	Cultural Requirements	Link Group	Type
ser-1	IIIR. Between sc (4%) and pro-1 (9%) (504). Uses serine or glycine (504). Slightly deficient in serine hydroxymethyltransferase: raised levels of 10-formyltetrahydrofolate synthetase. Lacks ability to incorporate C1 units from glycine. Extracts lack detectable methylfolates. Negligibly deficient in 5,10-methylene tetrahydrofolate reductase. (209). Ascospores from ser-1 x ser-1crosses do not blacken or do so only after a long delay (816). Morphologically normal; abnormal morphology at elevated temperatures that was reported in reference 816 was not due to ser-1 but to scot (810).	IIIR	B
pr(Sk-2)	IIIR. Between ser-1 and ad-4. Within the recombination block that is associated with Sk-2. Confers partial resistance to the killing of ascospores by Sk-2.	IIIR	B
