TABLE 5.

Mating efficiency conferred by Fig2p and different Aga1 proteins

Interacting pairs	Mating %
WT−WT	56.96 ± 5.74 (a)
Fig2p−none	0.00008 ± 0.00001 (c)
Fig2p−Aga1p	19.19 ± 3.65 (b)
Fig2p−(Aga1p−WCPLΔ)	2.17 ± 0. 44 (c)
Fig2p−(Aga1p−CX4CΔ)	0.84 ± 0.19 (c)
Fig2p−(Aga1p−WCPLΔCX4CΔ)	0.00069 ± 0.00038 (c)
Fig2p−(Aga1p−CX2CΔ)	20.65 ± 1.35 (b)

A quantitative mating assay was performed on crosses between a MATa aga1 aga2 strain and the MATα mating partners as shown in Figure 3A. In all of the crosses except the wild type, the only adhesin interaction present is that between Fig2p and different forms of Aga1p (wild-type or truncated proteins lacking different domains). The letters after the mating percentages indicate statistical significance, with the same letter indicating no significant differences at α = 0.05 level.
