PFT1 Is Required for Basal Resistance to the Leaf-Infecting Necrotrophic Pathogens A. brassicicola and B. cinerea.

(A) Schematic representation of the PFT1 gene and the locations of two independent T-DNA insertions designated as pft1-2 (SALK_129555) and pft1-3 (SALK_059316). Introns (solid line) and exons (boxes) are indicated.

(B) Symptoms on rosette leaves of 4-week-old soil-grown wild-type, pft1-2, and pft1-3 plants 2 weeks following drop inoculation with freshly harvested spores of A. brassicicola.

(C) The percentages of leaves showing chlorotic regions calculated 2 weeks after inoculations with A. brassicicola.

(D) Symptoms on rosette leaves of 4-week-old soil-grown wild-type, pft1-2, and pft1-3 plants following drop inoculation with freshly harvested spores of B. cinerea.

(E) The average lesion diameter measured 4 d after inoculation with B. cinerea.

Error bars in (C) and (E) represent se from three replicated experiments that contained 20 to 30 plants each.
