erg-1	VR. Between pk (2%) and asn (9%) (419).The cell membrane is deficient in ergosterol, conferring strong resistance to nystatin and other polyene antibiotics (418, 419). Defective in conversion of fecosterol to episterol (Fig. 13.). Lacks fecosterol delta8,delta7-isomerase (419). Infertile as female. Slow growth, reduced conidiation. The nysrmutants of reference 699 are blocked in the same reaction, but nysr has not been tested for allelism with erg-1.	VR	B
