FIGURES AND TABLE LIST
FIGURE 1. Tricoplusia ni plant consumption for five crops. Graph show differences between the control (CTRL) and insect (INSECT) groups for fresh biomass in the first sowing. The numbers in percent, above the bars correspond to the difference in percentage in plant consumption for the control group and the treatment for each cultivated plant. The numbers with two decimal places on each of the bars, corresponds to the average of six repetitions evaluated for the variable fresh biomass. The numerical averages are represented in grams. (*) Statistical significance was tested using ANOVA one-way test (p<0.05) followed by the test T-Student (Bonferroni) for each one of the crop plants separately.
FIGURE 2. Principal coordinate analysis (PCoA) ofpairwise dissimilarities (Bray–Curtis index) for bacterial communities in Arabidopsis , tomato, red beet, sweet corn, and bean rhizospheres of (A) Insect attack group and (B) Control group.
FIGURE 3. Principal coordinates analysis (PCoA) of pairwise dissimilarities (Bray–Curtis index) for bacterial rhizosphere communities in taxonomic composition present in (A) sweet corn,(B) beans, (C) A. thaliana , (D)tomato, and (E) red beet. The PCoA compares rhizosphere in control groups and rhizosphere after the insect attack. *PERMANOVA (p<0.05) and ns PERMANOVA(p<0.05). (E, F, G, H, I). Taxonomical composition of bacteria by phylum level in (F) sweet corn, (G) beans,(H) A. thaliana , (I) tomato, and (J)red beet. The relative abundance of each phylum is shown in a scale from 0 to 100%. *ANOVA & Tukey’s HSD post-hoc test (p< 0.05) and ns ANOVA & Tukey’s HSD post-hoc test( p<0.05).
FIGURE 4. Venn diagram showing the distribution of common ASVs assigned to the indicated genus among different plant species between the (A) insect attack group and (B) control group. The names from the genera in the Venn diagrams that are specific for each experimental group (eleven to insect group and nine to control group) and shared between the groups (forty-nine) are shown in supplementary table 6.
FIGURE 5. Difference in plant biomass between the control group (CTRL) and insect group (INSECT) in the second sowing. The numbers above the bars correspond to the difference in percentage between the two groups for each cultivated plant. The numbers with two decimal places on each of the bars, corresponding to the average of six repetitions evaluated for the variable fresh biomass. The numerical averages are represented in grams. (*) ANOVA one-way significant forp< 0.05 followed by the T- Student test (Bonferroni).
TABLE 1. Eleven bacterial genera and their respective relative abundance across crop rhizosphere samples under insect attack.(A) Corn, (B) Beans, (C) A. thaliana ,(D) Tomato, and (E) Red Beet. Eleven taxa were analyzed based on their relative abundance values using analysis of variance (ANOVA) and Tukey’s HSD post-hoc test. Significant difference (p< 0.05) are highlighted and labeled (*).
