pyr-1	IVR. Right of psi (4%) and T(ALS159) (808, PB). Left of pdx-1 (<1 to 10%) (692). (482) Requires uracil or other pyrimidine. Lacks dihydroorotate dehydrogenase activity (133, 134) (Fig. 20). All ascospores from pyr-1 x pyr-1crosses are white if cross is on medium containing 0.1 mg of uracil per ml; they are black if the cross is on medium containing 1.0 mg/ml (632).	IVR	B
