AB  - Phytohormones are essential regulators of various processes in plant growth and 
      development. Several phytohormones are also known to regulate plant responses to 
      environmental stress and pathogens. Only recently, cytokinins have been 
      demonstrated to play an important role in plant immunity. Increased levels of 
      cytokinins such as trans-zeatin, which are considered highly active, induced 
      resistance against mainly (hemi)biotrophic pathogens in different plant species. 
      In contrast, cis-zeatin is commonly regarded as a cytokinin exhibiting low or no 
      activity. Here we comparatively study the impact of both zeatin isomers on the 
      infection of Nicotiana tabacum by the (hemi)biotrophic microbial pathogen 
      Pseudomonas syringae. We demonstrate a biological effect of cis-zeatin and a 
      differential effect of the two zeatin isomers on symptom development, defense 
      responses and bacterial multiplication.
