Beneficial Bacteria for Disease Suppression and Plant Growth Promotion

Chapter

Abstract

Beneficial plant-microbe interactions in the rhizosphere are major factors in determining soil fertility and thus plant productivity and health. Plant growth-promoting bacteria (PGPB) can establish intimate associations with host plants via a great variety of mechanisms, which enhance plant growth and protect them from various biotic (e.g., phytopathogens) and abiotic stresses (e.g., drought, extreme temperature, salinity, and heavy metals). To meet the needs of sustainable and eco-friendly approach of agriculture, the use of transgenic plants and PGPB has been recommended as a part of mainstream agricultural applications. Since PGPB inoculation is more easily manipulated compared to transgenic plants, the application of PGPB in agriculture has attracted increasing attention. This article reviews the importance of plant-microbe interactions to the development of efficient PGPB inoculants and progresses of the recent researches on the role of PGPB to improve plant growth and health for sustainable agriculture.

Keywords
