Basal resistance (BR, a local resistance against pathogens induced by general elicitors) is a multi-faceted defence mechanism appearing in many shapes and with many given names, such as induced (acquired) resistance (protection, defence), as well as a part of innate immunity. Here, we give a historical overview of concepts, present results and an outlook associated with bacteriological studies in the Plant Protection Institute (PPI). The topics on BR briefly covered are its elicitors, light and temperature dependence, changes in plant physiology, transcription and protein expression during it and its effect on bacteria. We emphasize the importance and relevance of its quick form, early BR, which might be a plant defence mechanism in nature against all kinds of pathogenic and saprophytic bacteria.
