In-vitro colonization of沙门氏菌is dependent on lateral roots. (a) Representative image depicting沙门氏菌(mcherry tagged) colonization near the lateral root emerging area. Root is stained with DAPI. (b) Number of lateral roots upon inoculation of various organisms on Day 1, 5 and 10. ANOVA was used to analyze the data. The comparison shown is between uninfected and infected plants at 10th day. *** = P < 0.001; ns = not significant. (c)沙门氏菌colonization upon inhibition and induction of lateral roots by NAA for Col-0 andaxr 1–3respectively. ANOVA was used to evaluate the significance. *** = P < 0.001. Each experiment was repeated 3 times with 5 replicate each. (d) Correlation of沙门氏菌colonization with lateral root (at 95% CI).Ralstonia solanacearum ΔhrpBwas used as positive control andE.coliwas used as non phytopathogenic bacteria control respectively.N = 50 for each organism for calculating correlation
