Molecular Characterization of Abiotic Stress Tolerant Chickpea Rhizobia

Abstract

Rhizobacteria are root-colonizing bacteria that form a symbiotic relationship with many legumes. Though parasitic varieties of rhizobacteria exist, the term usually refers to bacteria that form a relationship beneficial for both the parties (mutualism). Such bacteria are often referred to as plant growth promoting rhizobacterias (PGPRs). Though microbial inoculants are indisputably beneficial for crops, they are not widely used in industrial agriculture, as large-scale application techniques have yet to become economically viable. Many rhizobial and fungal pathogens are not restricted to infecting aerial or root tissues exclusively. As such, communication between aboveground and belowground components can confer a survival advantage and potentially limit or prevent diseases. Current literature suggests that the metabolic levels of low-M_r compounds play a significant role in triggering plant innate defense responses. A corresponding induced defense response initiating intraplant signaling between leaves and roots has been implicated in herbivory.
