FIG 5.

Comparison of in planta and extract growth rates for E. coli isolates Sakai and ZAP1589. Growth rates for in planta estimates were plotted against estimates for plant extracts on a log₁₀(number of CFU day⁻¹ [d⁻¹]) basis for E. coli isolates Sakai and ZAP1589 and were normalized per gram (fresh weight) for plant tissues or per milliliter for plant extracts. Estimates were obtained for growth at 25°C for sprouted seeds (alfalfa [Alf], fenugreek [Fen]) and at 18°C for spinach (Sp.) or lettuce (Lt.) tissues (A, apoplast; L, leaves; R, roots).
