Table 2.

Multiple response permutation procedure (MRPP) of differences in phyllosphere bacteria structure between symptomatic and asymptomatic group.

Group	A	Observed-delta	Expected-delta	Significance (p value)
he1-in1	0.06706	0.28	0.3001	0.011
he2-in2	0.2777	0.3075	0.4258	0.007
he3-in3	0.4039	0.3196	0.5361	0.009
he4-in4	0.6013	0.195	0.4891	0.008
he5-in5	0.4341	0.238	0.4206	0.004

Smaller values of Observe-delta indicate smaller within-group differences, and larger values of Expect-delta indicate larger between-group differences. A > 0, Between-group differences were greater than within-group differences; A < 0, Differences within groups were greater than differences between groups. Significance < 0.05, the difference is significant.
