ergosterol-4

locus: erg-4

locus_name: ergosterol-4

organism_type: B

chromosome_number: I

chromosome_side: R

link_group: IR

cultural_requirements: IR. Linked to al-1 (10%) (PB).The cell membrane is deficient in ergosterol, conferring slight resistance to nystatin. Lacks C24 (zymosterol)-methyl transferase. Accumulates zymosterol (Fig. 13.). Infertile as female (419). Slow growth, colonial at 34 C, spreading at 25°C (PB)
