Rhizosphere Microorganisms with Different Strategies and Mechanisms to Enhance Plant Growth in the Occurrence of Different Environmental Stress Factors

Every minute, the world’s population grows, and in order to feed them, crop output agricultural productivity must be improved by adding crucial microorganisms that boost plant yields various ways through nitrogen fixation, secretion of both growth regulators 1-aminocyclopropane 1-carboxylate deaminase, as well some antimicrobial agents. Numerous endophytic bacteria have recently been used increase yields, production addition reducing salt stresses. Many scientists made an effort clarify comprehend processes which promote production. A vital substance known 1-aminocyclopropane-1-carboxylate (ACC) deaminase is produced several bacteria, plants, fungi decrease ethylene levels a grown under different environmental stress. The gaseous hormone (C2H4) synthesized tissues from precursor ACC, it has numerous biochemical roles such cells differentiation tissue development, seedling, root hair, leaf, flower development fruit ripening formation anthocyanin volatile compounds. Thus, this critical enzyme had influential plants during their positive interaction with due auxin protect against stress like drought, high salts, wilting, level heavy metals, contaminants pesticides, microbial pathogen infections. Different bacterial genera are highly ACC deaminase-producer, these support process. In conclusion, can replace chemicals variety environmentally benign methods soil fertility productivity. However, much research required determine efficacy before suggesting use on broad scale field.
