Plant Growth-Promoting Rhizobacteria in Management of Biotic and Abiotic Stresses

Abstract

Plant Growth-Promoting Rhizobacteria (PGPR) modifies the activity of the relevant genes to affect the physiological traits, metabolites, pathways, and proteins of plants. Traditional methods for creating salt-tolerant crops are expensive, laborious, and occasionally difficult to adopt. It has been proposed that using microorganisms that encourage plant growth is a suitable and economical method of raising plant tolerance. These evocative microbes can act as a mediator between plants and their morphological, physiological, and molecular responses. Extensive research has been done on the signaling pathways used by hormones, plant receptors, and microbial signals to stimulate PGPR in plants. This chapter aims to increase comprehension of the convergence mechanisms used by these signaling molecules as well as the ambiguities of signaling activities that occur in the host as a result of interactions with PGPR under demanding environmental situations. In order to address biotic and abiotic stressors in agricultural areas and hence raise global food production, the use of rhizobacteria inoculants is a viable strategy.
