Abstract
Plants recognize the infection of both pathogenic and non-pathogenic bacteria and respond with specific and non-specific defense reactions after bacterial infections. One of the specific defense responses of plants is the hypersensitive reaction (HR). The HR is accompanied by an accumulation of active oxygen species including H2O2 and other resistance associated responses. The hrp/hrc genes are indispensable for phytopathogenic bacteria to induce HR or disease in plants. The plant cells sense not only the plant pathogenic bacteria and their elicitors (harpin or avr proteins) but also the non-pathogenic and the HR-negative bacteria (non-specific reactions). During these non-specific reactions plants respond with different resistance related reactions such as induction of mRNA accumulation of several defense associated genes, and large papilla formation at the site of attachment of bacteria. The plants probably recognize the bacterial common surface molecules e.g. flagellin protein (1) or bacterial lipopolysaccharides (2, Kecskés et al., unpublished).
