A Pathogen-Responsive cDNA from Potato Encodes a Protein with Homology to a Phosphate Starvation-Induced Phosphatase
Institute of Plant Biochemistry, Department of Stress and Developmental Biology, Weinberg 3, D-06120 Halle / Saale, Germany
Abstract
Infiltration of potato leaves with the phytopathogenic bacteria Pseudomonas syringae pv. maculicola induces local and systemic defense gene expression as well as increased resistance against subsequent pathogen attacks. By cDNA-AFLP a gene was identified that is activated locally in potato leaves in response to bacterial infiltration and after infection with Phytophthora infestans, the causal agent of late blight disease. The encoded protein has high homology to a phosphate starvation-induced acid phosphatase from tomato. Possibly, decreased phosphate availability after pathogen infection acts as a signal for the activation of the potato phosphatase gene.
