serine-1

locus: ser-1

locus_name: serine-1

organism_type: B

chromosome_number: III

chromosome_side: R

link_group: IIIR

cultural_requirements: 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).
