Bacteria in the leaf ecosystem with emphasis on Pseudomonas syringae -- a pathogen, ice nucleus, and epiphyte

Article Abstract:

Pseudomonas syringae is the most well-researched example of plant-microorganism interactions. It is a pathogen but can also live on the surface of healthy leaves as an epiphyte.

Dynamics, spread, and persistence of a single genotype of Pseudomonas syringae relative to those of its conspecifics on populations of snap bean leaflets

Article Abstract:

The various aspects of the ecology of Pseudomonas syringae was studied. Different sampling procedures were used to determine the population dynamics, the spread, the likelihood of its growth and persistence in the generations of the host plant of the introduced Pseudomonas genotype. The likelihood of growth by a bacteria on a leaf surface distant from its site of introduction was emphasized.

Raindrop momentum triggers growth of leaf-associated populations of Pseudomonas syringae on field-grown snap bean plants

Article Abstract:

The momentum of raindrops increases the population size of the phytopathogenic bacteria Pseudomonas syringae pv. syringae present on the leaves of the snap bean Phaseolus vulgaris L. The bacterial population size on bean plants covered by a fine mesh screen shows no change. The effect of rain is due to its momentum as the screens affect only the momentum and have no effect on the quality or volume of rain that falls on the plants. Rainfalls that last for one to three days increase the bacterial population size by 10 to 1,000 times.
