Abstract

We have cloned theerg-3 gene, which encodes the ergosterol biosynthetic enzyme sterol C-14 reductase, from the tomato pathogenic fungusSeptoria lycopersici. Its nucleotide sequence, reported here, encodes a 512-amino-acid polypeptide with 54% sequence identity to sterol C-14 reductase ofNeurospora crassa. TheSeptoria gene complemented the pisatin-sensitive, tomatine-resistant and female-sterile phenotypes of aNeurospora erg-3 mutant.
