Tumor Induction by Pseudomonas savastonai

About Pseudomonas 

 The genus Pseudomonas is a group of ubiquitous microorganisms found in diverse habitats such as water, soil, and plant surfaces. 

 It has simple nutritional requirements. 

 It is a gram-negative bacterium. 

 It is a motile, rod shaped bacterium with polar flagella. 

 The rhizosphere is a microbial zone area in which root associated pseudomonads play a important role as plant health managers. 

 Beneficial Pseudomonas are rapid root colonizers, they directly and indirectly improving plant growth and yield.

Tumor induction by Pseudomonas savastonai 

 P.savastonai cuses KNOTS and GALL on members of genera Oleaceae. 

  Symptoms of infected plant include OVERGROWTH on the stem and branches of host plants. 

  Overgrowth may also be seen on leaves and fruits. 

  At present only P. savastonia determinant is known to be involved in knot development. 

  It is also involved in Auxin and Cytokinin biosynthesis. 

  Also known as Plant Growth Promoting bacteria. 

  Symptoms of infected trees include hyperplastic growths (tumorous galls or knots) on the stems and branches of the host plant and, occasionally, on leaves and fruits.
