ANOVA results for the effect of addition of inosine monophosphate (IMP) on chorda tympani (CT) fibre responses to amino acids in WT, T1R3-KO and TRPM5-KO mice

Fibre type
Strain	S1	S2	M1	M2
WT	F(1,106) = 106.6***	F(1,94) = 1.76	F(1,72) = 4.84*	F(1,85) = 0.39
T1R3-KO	Not found	F(1,68) = 3.08	F(1,56) = 4.76	F(1,118) = 0.09
TRPM5-KO	Not found	F(1,70) = 0.08	F(1,71) = 7.36**	F(1,124) = 0.08

Differences between CT fibre responses to amino acids (0.1 m MPG, 0.1 m Cys, 0.1 m l-Ala, 0.1 m l-ArgHCl, 0.1 m l-LysHCl, 10 mm l-AP4, 10 mm Quis and 10 mm NMDA) with 0.5 mm IMP and the sum of each component were assessed by two-way ANOVA. ‘Not found’, no such fibre was identified.
