blt1∆/gef2∆ mutant cells have decreased viability and are elongated at the completion of division. a Growth at 26 °C for 72 h or 37 °C for 48 h on YE5S agar plates with aliquots of 10-fold serial dilutions of wildtype cells (blt1⁺/gef2⁺) and blt1∆, gef2∆, and blt1∆/gef2∆ mutant strains. b Histograms of the mean cell length ± 1 SD in septated cells prior to the initiation of cell wall indentation for wildtype (blt1⁺/gef2⁺), blt1∆, gef2∆, and blt1∆/gef2∆ cells (n ≥ 25 cells for each condition). Asterisks indicate mean values of wildtype and mutant cells (blt1∆, gef2∆, blt1∆/gef2∆) that differed with p < 0.001. c White light transmission micrographs of wildtype (blt1⁺/gef2⁺), blt1∆, gef2∆, and blt1∆/gef2∆ cells. Scale bar = 10 μm.
