Yeast replicative lifespan and terminal morphology in culture media of varying pH

The replicative lifespan of yeast (BY4742 strain background) cultured in media of varying pH. Column L (“lifespans”; LS) through AE represent the number of daughter cells produced by each mother cell and the endCode (column AF-AY) represents the terminal morphology of the corresponding numbered mother cell. End lost represents the number of cells that did not receive a terminal cell morphology designation. U = unbudded, S = small bud (<50% size of mother), L = large bud (>=50% size of mother), C = cluster of cells.
