  • a Complete genotypes of the strains are listed in Table 1.

  • b Relative proportion of cells exhibitingINT1-induced filaments. In each case, the strain was compared with the appropriate isogenic or congenic wild-type strain listed in Table 1. +++, similar to wild type; ++, ∼25 to 75% of wild-type levels; +, less than 25% of wild-type levels of filament formation.

  • c Appearance of filaments relative to how they appeared in the isogenic or congenic wild-type strains. wt, filaments were indistinguishable from wild-type filaments; sh, average filament length was shorter than in the relevant wild-type strain; shm, polarized cells appeared similar to mating projections (shmoos).
