Pseudomonas syringae - Gram-negative, aerobic, enteric, rod prokaryote. Pseudomonas syringae is a plant pathogen which can infect a wide range of plant species, and occurs as over 50 different pathovars. Pseudomonas syringae can act as nuclei for the formation of ice crystals once the temperature falls below a certain level. This ability was discovered during research into frost prevention for plants. The ice-minus variant of P. syringae a mutant, lacking the gene responsible for ice-nucleating surface protein production. This lack of surface protein provides a less favorable environment for ice formation. Pseudomonas spp. are able to grow in extreme environments. Any carbon or hydrocarbon source is a suitable place for them to live. The bacterial genus Pseudomonas (pseudomonad) includes plant pathogenic bacteria such as P. syringae, the human pathogen P. aeruginosa, the ubiquitous soil bacterium P. putida, and some species that are known to cause problems in dairy products. P. aeruginosa usually causes problems to humans who have already have had their immune systems weakened.
