Microorganisms Used as Growth Regulators in Modern Agriculture

Abstract

Biofertilizers and biological products are increasingly being used to enlarge the productivity of crops. Of these, microbes known as Plant Growth-Promoting Microorganisms (PGPM) are the most valuable as biofertilizers, having the capacity to directly impact the growth and development of plants. Plant Growth-Promoting Fungi (PGPF) and Plant Growth-Promoting Bacteria (PGPB) help crops to face biotic and abiotic stresses by enhancing the defense system and several other parameters related to plant growth. This chapter is focused on explaining the function and positive influence of the PGPF and PGPB on several crops, and also to provide a general view of the application of microorganisms in modern agriculture.
