Infiltration of Agrobacterium tumefaciens in Avr2/I-2 tomato plants triggers cell death. (A) Four-week-old wild-type Moneymaker, I-2 and Avr2/I-2 tomato plants infiltrated with either infiltration buffer (“-”) or Agrobacterium expressing GUS or ΔspAvr2. The left side of each leaf is buffer infiltrated and the right site is infiltrated with Agrobacterium carrying either a GUS or ΔspAvr2 construct. Photographs were taken 4 dpi. The bottom panel shows the same leaves stained with trypan blue to visualize cell death. (B) 20 leaves of wild-type Moneymaker, I-2 and Avr2/I-2 tomato plants were scored for their response following infiltration. The assay was repeated twice with similar results.
