Abstract Background The tomato kinase Pto confers resistance to bacterial speck disease caused by Pseudomonas syringae pv. tomato in a gene for gene manner. Upon recognition of specific avirulence factors the Pto kinase activates multiple signal transduction pathways culminating in induction of pathogen defense. The soluble cytoplasmic serine threonine kinase Pti1 is one target of Pto phosphorylation and is involved in the hypersensitive response HR reaction. However a clear role of Pti1 in plant pathogen resistance is uncertain. So far no Pti1 homologues from monocotyledonous species have been studied. Results Here we report the identification and molecular analysis of four Pti1-like kinases from maize ZmPti1a
