Mycorrhizal colonization rates, disease incidences, and indices of AMF-inoculated and un-inoculated tomato plants inoculated by AMF Funneliformis mosseae and pathogen A. solani.

Microbial inoculation	Tomato genotype	Disease incidence (%)	Disease index (%)	Mycorrhizal colonization (%)
F. mosseae and A. solani	WT	60.2 ± 1.3 cd	36.8 ± 1.3 c	40.6 ± 4.1 a
	35S::PS	54.5 ± 4.4 d	28.5 ± 1.7 d	41.2 ± 1.2 a
	spr2	86.4 ± 2.1 a	53.4 ± 1.4 a	14.0 ± 1.9 b
A. solani	WT	73.1 ± 3.1 b	43.6 ± 2.4 b	0 c
	35S::PS	67.9 ± 3.6 bc	35.8 ± 1.2 c	0 c
	spr2	89.6 ± 1.4 a	56.2 ± 1.4 a	0 c

Three tomato genotypes included: (1) WT: wild type plant; (2) 35S::PS: Prosystemin-overexpressing 35S::PS plant; (3) spr2: JA biosynthesis mutant plant. Four sets of bioassays were independently carried out and three pots per treatment were set up for each set of bioassays. Values are means ± SE. Significant differences (P < 0.05 using Tukey post hoc test) among treatments in the same column are indicated by different letters.
