ABSTRACT
ABSTRACT Plant pathogenic bacteria (PPB) cause signicant economic losses globally in a wide variety of crops. In order to devise robust management strategies against these bacterial diseases, comprehensive understanding of varied aspects of their growth, multiplication, virulence, and modes of action is mandatory. Specically, the factors responsible for the are-ups of these bacterial diseases in economically important plants require much attention. This endeavor must include a thorough understanding of the growth habits and preferences of PPB. Herein, we highlight the most economically signicant bacterial diseases worldwide and critically discuss the different major and minor nutrient sources commonly used for in vitro culturing of PPB. The preferences by PPB to these nutrient supplements for growth and multiplication are also reviewed, and the roles of these nutrient supplements in promoting virulence or its suppression under in vitro conditions are compiled. Aspects related to exopolysaccharide (EPS) production, hypersensitive response and pathogenicity (Hrp) genes, and their induction in different PPB are reviewed as well. Last, the types of nutrients that trigger hypersensitive response (HR) in resistant plants and non-hosts is considered.
