Sporulation efficiency and spore viability in S. cerevisiae cells expressing S. c. or K. l. ZIP1.

Sporulation efficiency and viability of spores produced by strains expressing either S. c. ZIP1 or K. l. ZIP1. Sporulation efficiency is the fraction of total sporulating cells that are 2, 3 or 4-spore asci. The far right column shows the overall spore viability of each strain. Displayed in each “Distribution of tetrad types” column is the frequency of tetrads containing four viable spores (4-sv), three viable spores (3-sv), two viable spores (2-sv), one viable spore (1-sv) or no viable spores (0-sv). Full strain genotypes are listed in S6 Table.
