Growth of Pst(avrPto) (A)
or Pst (B) in leaves of near-isogenic
lines containing different Pto loci. Four-week-old
plants of TA209 (L. esculentum Pto locus, ○),
TA537 (L. pimpinellifolium Pto locus, ■), and
96T133-3 (L. hirsutum Pto locus, ▴) were
vacuum-infiltrated with 105 colony-forming units per
milliliter (cfu/ml) of Pseudomonas, and bacterial
growth was measured as cfu/ml at the time points specified. Each time
point represents the average of three samples. Each sample contains
three 1-cm2 leaf discs in 1 ml of 10 mM MgCl2.
The error bars represent the standard error.
