os-1	IR. Between nic-1 (10 to 29%) and arg-13 (1%) (789, 812, 816). (M.R. Emerson, cited in reference 789) Sensitive to high osmotic pressure. Readily scored by morphology on nonmoist slants or by failure to grow on media with 4% NaCl. Most os-1 alleles result in cultures that form no or few conidia on agar slants. Alleles NM233t and NM204t are heat sensitive (25°C versus 34°C). In media of high osmolarity, os-1 strains form protoplasts (323, 438). os-1 (Bl35) is an essential genotypic component of the wall-less strain slime (321). Protoplasts of strains carrying heatsensitive allele NM233t are stable at 37 C, with a 7.5-h redoubling time, and show good regeneration. The biochemical defect differs from that affected by either polyoxin or sorbose (chitin or glucan syntheses) (970, 971). Cell wall pores are four times larger in an os-1 mutant than in the wild type; os-1 also has a higher exclusion threshold and a 30-fold-higher galactosamine/ glucosamine ratio (1083, 1084). Intralocus complementation (676). Allele Y256M209 called flm-1.	IR	B
