Pseudomonas syringae is a aerobic bacterium that has both pathogenic and non-pathogenic strains. Optimal temperature for the pathogenic strain is a damp surface with temperatures between 12-25 °C, depending on this specific pathovar. P. syringae tends to be dispersed between plants by rain dispersal on seeds. There have been a number of studies that suggests that this species also can also do well in stressful conditions such as the dry environment of intracellular spaces on leaf surfaces and other plant tissues. This species is commonly associated with a variety of apple, cherries, bananas, citrus fruits, tomatoes, beans, and a number of other fruit and vegetable plants.

 

Pseudomonas syringae is a bacterium hence it's growth is not measured in terms of individual cell such as animal or plant growth, but is rather measured in terms of growth of the population of the species as a whole. The major steps that bacterial growth is determined by over time is the initial lag phase(A), the exponential growth phase (B), the stationary phase (C), and the exponential death phase (D).
 

 

 

 

 

 

 

• Individual bacterial growth occurs through a process called binary fission. Binary fission is a form of asexual reproduction by which one cell divides into two cells of equal size with the relatively equal sized cell parts.
