Pseudomonas Syringae Research Paper

Pseudomonas syringae

Finding a bacterium that I felt even a shred of confidence to discuss in a paper was no easy task, but while doing research I discovered this (probably more well-known than I realize) bacteria that had some properties that were incredibly interesting to me. The basic properties of Pseudomonas syringae is that it 's gram-negative, has a rod-shaped morphology, and is an aerobic respirator. It 's categorized as gram-negative due to crystal violet being washed away, and stained pink by the counter stain safranin during a gram-stain. The crystal violet can be washed away due to a gram-negative organisms thinner peptidoglycan layer. It 's rod-shappedness is merely a morphological characteristic, and doesn 't seemingly mean much in describing it 's toxicity in plants. It 's aerobic nature is characterized by utilizing oxygen to create energy. More specifically oxygen is the final electron acceptor in the Electron Transport Chain for Pseudomonas syringae which is responsible for most of it 's energy production.
It 's pathogenic nature, and the reason I found this bacteria so interesting was it 's ability to produce ice nucleation (INA) proteins. When these proteins are present water 's freezing point is drastically higher causing damage to plants when the freezing occurs. Only one strain of Pseudomonas syringae can infect one species of plant generally. It was implicated during my research that because it has a different strain for all the species it can infect that it 's metabolism is hard to generalize since each strain has a fairly unique metabolism which is geared toward the plant it 's most suited for. There is a vast amount of information about Pseudomonas syringae 's pathogenicity in plants, but I wanted to discuss potentially Pseudomonas syringae 's most incredible attribute, which is it 's importance in the production of rain and
