Genetic interactions of SmB-Ala mutants. Yeast smb1▵ strains bearing the indicated SMB1-Ala allele on a CEN HIS3 plasmid in an otherwise wild-type (top panel), mud2▵, mud1▵, nam8▵, or tgs1▵ background as indicated were spot-tested for growth on YPD agar at the temperatures specified. Synthetic growth defects are denoted by •.
