Locus	Cultural Requirements	Link Group	Type
phe-2	IIIR. Linked to vel (1%), between T(D305) and tyr-1(2 to 4%) (40, 316, 809). Lacks prephenic dehydratase (40, 316) (Fig. 11). Requirement is very leaky. Grows extensively and is treacherous to score by growth on minimal versus supplemented medium, but can be scored reliably by blue fluorescence under long-wave UV after growth on minimal medium without phenylalanine (816). Appearance of phenylalanine in culture medium (118) is due to spontaneous conversion of accumulated pretyrosine (519). Called phen-2. Allele Y16329 formerly called phen-3 (316).	IIIR	B
