“…Ethylene precursor aminocyclopropane-1-carboxylate (ACC), synthesized by plants in response to exposure to several types of environmental stress, such as drought, flooding, cold, high temperature, extreme light, presence of toxic heavy metals and organic pollutants, radiations, wounding, high salt, insect predation, various pathogen infection including fungi, bacteria, and viruses [291,342] ( Figure 4). To improve the growth and stress tolerance, ACC-deaminase producing bacteria considered as a possible biological approach in plants by decreasing the endogenous level of ethylene [343]. During salt stress conditions PGPR produces ACC-deaminase, which lowers ethylene level in plants [226].…”

Plant growth‐promoting rhizobacteria (PGPR) are diverse groups of plant‐associated microorganisms, which can reduce the severity or incidence of disease during antagonism among bacteria and soil‐borne pathogens, as well as by influencing a systemic resistance to elicit defense response in host plants. An amalgamation of various strains of PGPR has improved the efficacy by enhancing the systemic resistance opposed to various pathogens affecting the crop. Many PGPR used with seed treatment causes structural improvement of the cell wall and physiological/biochemical changes leading to the synthesis of proteins, peptides, and chemicals occupied in plant defense mechanisms. The major determinants of PGPR‐mediated induced systemic resistance (ISR) are lipopolysaccharides, lipopeptides, siderophores, pyocyanin, antibiotics 2,4‐diacetylphoroglucinol, the volatile 2,3‐butanediol, N‐alkylated benzylamine, and iron‐regulated compounds. Many PGPR inoculants have been commercialized and these inoculants consequently aid in the improvement of crop growth yield and provide effective reinforcement to the crop from disease, whereas other inoculants are used as biofertilizers for native as well as crops growing at diverse extreme habitat and exhibit multifunctional plant growth‐promoting attributes. A number of applications of PGPR formulation are needed to maintain the resistance levels in crop plants. Several microarray‐based studies have been done to identify the genes, which are associated with PGPR‐induced systemic resistance. Identification of these genes associated with ISR‐mediating disease suppression and biochemical changes in the crop plant is one of the essential steps in understanding the disease resistance mechanisms in crops. Therefore, in this review, we discuss the PGPR‐mediated innovative methods, focusing on the mode of action of compounds authorized that may be significant in the development contributing to enhance plant growth, disease resistance, and serve as an efficient bioinoculants for sustainable agriculture. The review also highlights current research progress in this field with a special emphasis on challenges, limitations, and their environmental and economic advantages.

“…Under drought, an increase in hydrolytic enzymes responsible for breaking down complex carbohydrates such as lignin, cellulose, and other plant metabolites within the microbial communities has been shown (Bouskill et al, 2016). Additionally, bacteria can alter ethylene production within the plant with ACC deaminase (Arshad et al, 2008), which in turn alters plant growth and metabolite profiles to the benefit of plants and microbes (Mayak et al, 2004; Zhang et al, 2018). Not only can the host plant alter its exudate profile to recruit organisms, the microbial community can influence what compounds are being exuded, potentially creating a reciprocal relationship between the community and exudate profile.…”

Plants serve as host to numerous microorganisms. The members of these microbial communities interact among each other and with the plant, and there is increasing evidence to suggest that the microbial community may promote plant growth, improve drought tolerance, facilitate pathogen defense and even assist in environmental remediation. Therefore, it is important to better understand the mechanisms that influence the composition and structure of microbial communities, and what role the host may play in the recruitment and control of its microbiome. In particular, there is a growing body of research to suggest that plant defense systems not only provide a layer of protection against pathogens but may also actively manage the composition of the overall microbiome. In this review, we provide an overview of the current research into mechanisms employed by the plant host to select for and control its microbiome. We specifically review recent research that expands upon the role of keystone microbial species, phytohormones, and abiotic stress, and in how they relate to plant driven dynamic microbial structuring.

“…Different bacterial groups inhabiting rhizospheric soil commonly consume ACC as the sole source of nitrogen. Arthrobacter, Bacillus, Burkholderia phytofirmans, Pseudomonas fluorescens, Pseudomonas putida, Klebsiella, Serratia, Enterobacter and Microbacterium are examples of ACC deaminase-containing bacterial species that have been reported to promote growth of different plants species (e.g., Brassica napus (canola), Oryza sativa (rice), and Triticum aestivum (wheat) (Sarkar et al, 2018, Zhang et al, 2018, Shameer and Prasad, 2018Mishra, et al, 2018). Salinity is an important obstacle limiting agricultural production and expansion of cultivated areas, which affects most areas of Saudi Arabia and other arid regions.…”

Plant growth-promoting bacteria are present in the rhizosphere, a soil zone around plant roots. An important mechanism of plant growth enhancement is the production of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase. Three ACC deaminase-producing bacterial strains were isolated from the rhizosphere of the halophytic plant Zygophyllum coccineum growing in Al-Uqair, Al-Ahsa, Saudi Arabia. The strains were identified as Bacillus filamentosus, Janibacter indicus, and Brevibacterium casei based on 16S rRNA sequence, and their taxonomic position was determined. Furthermore, the strains exhibited catalase and indoleacetic acid production and phosphate solubilization. The highest ACC deaminase activity was observed in B. filamentosus (~ 449 nmole α-ketobutyrate mg-1 h-1), followed by J. indicus and B. casei (~ 66 nmole α-ketobutyrate mg-1 h-1). Inoculation of wheat grains with each strain significantly enhanced growth. Z. coccineum rhizosphere harbors growth-promoting bacteria and ameliorated the negative effects of salt stress on wheat plants and may be used as an eco-friendly biofertilizer.
