Pseudomonas Syringae: An Overview and its future as a "Rain Making Bacteria"

Bioprecipitation is a process of precipitating water by precipitation causing microorganisms by its ice nucleating properties. The concept of rain-making bacteria is known since 1980’s but lack of research data makes it unrevised. Pseudomonas syringae is a Gram-negative bacterium mostly known to have ice-nucleating properties causing plant diseases. Their huge numbers of pathovars were identified in different hosts each having different modes of action. As always known for its pathogenesis in plant species with its ice-nucleating gene (ina), a concept of ice minus bacteria was created in 1970’s which is against wild type P.syringae. So the bacterium lacking ice nucleating gene (ina) competed with wild type strain and succeeded. But findings say that a bacterium (wild type Pseudomonas syringae) was found on rain drops of different parts of the world and that bacterium is literally raining. More studies in this bacterium as a rainmaking element may give as a better chance to know more about its role in life cycle.
