Jh. Chang et al., avrPto enhances growth and necrosis caused by Pseudomonas syringae pv. tomato in tomato lines lacking either Pto or Prf, MOL PL MICR, 13(5), 2000, pp. 568-571
AvrPto was introduced into three tomato genotypes with two biotic agents to
study its role in compatible interactions. avrPto enhanced the capacity of
the Pseudomonas syringae pv. tomato strain T1 to induce necrotic symptoms
on tomato plants that lacked either Pto or Prf genes. The enhanced necrosis
correlated with a small increase in bacterial growth. In planta expression
of QvrPto in isolation did not elicit necrosis in the absence of a functio
nal Prf gene.
