PGPR‐mediated induction of systemic resistance and physiochemical alterations in plants against the pathogens: Current perspectives

et al. 2020

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.

“…The genera of PGPR that mostly stand out are Pseudomonas, Azospirillum, Azotobacter, Enterobacter, Bacillus, Rhizobium, among others (Berg, 2009;Barea, 2015;Kamou et al, 2015), which can be inoculated in plant, seed, root, or soil (Shen et al, 2013;Bashan et al, 2014). Plant response to PGPR inoculation varies considerably depending on rhizobacterial species, host, soil type, inoculum density, environmental conditions, and inoculation method (Berg, 2009;Shah et al, 2017). The method of incorporating PGPR has an influence on the establishment and permanency of bacterial populations in the rhizosphere and indirectly on its growth promoter effects (Sivakumar et al, 2014;He et al, 2016).…”

The objective of this study was to determine the efficiency of applying microcapsules and liquid inoculation of three Pseudomonas putida strains on growth and yield of tomato plants in greenhouse where the results showed differences between both treatments. Rhizobacterial strains FA-8, FA-56, and FA-60 of P. putida, were assessed individually and combined to determine their capacity to produce indoleacetic acid (IAA). The three strains demonstrated the capacity to produce IAA in vitro, of which FA-56 stood out with 23.02 µg mL -1 in the microcapsule treatment with significant increases in plant height, stem diameter, radical volume, dry biomass, fruit yield, and rhizobacterial population (CFU). These responses could have been associated to the intrinsic capacity of this strain to produce a greater amount of IAA, hormone related to promoting plant growth. The use of plant growth-promoting rhizobacteria (PGPR) as biofertilizers by means of microcapsules could be an alternative in agricultural management and sustainable production of tomato. Immobilization of P. putida rhizobacteria by alginate microcapsules confers protection and gradual release, improving adhesion, permanency, and colonization of cells on the roots, promoting a better effect as PGPR and productivity in tomato plants.Alginate microcapsules (mc) †MIX = mixture of three rhizobacterial strains of P. putida. ‡liquid medium bacterial (lm).Average values (n = 8) within the same column with different letters denote significant differences in the assay with randomized block design and Duncan's multiple range test (P < 0.05).

Plant growth–promoting rhizobacteria (PGPR) are a group of microorganisms of utmost interest in agricultural biotechnology for their stimulatory and protective effects on plants. Among the various PGPR species, some Pseudomonas putida strains combine outstanding traits such as phytohormone synthesis, nutrient solubilization, adaptation to different stress conditions, and excellent root colonization ability. In this review, we summarize the state of the art and the most relevant findings related to P. putida and its close relatives as PGPR, and we have compiled a detailed list of P. putida sensu stricto, sensu lato, and close relative strains that have been studied for their plant growth–promoting characteristics. However, the mere in vitro analysis of these characteristics does not guarantee correct plant performance under in vivo or field conditions. Therefore, the importance of studying adhesion and survival in the rhizosphere, as well as responses to environmental factors, is emphasized. Although numerous strains of this species have shown good performance in field trials, their use in commercial products is still very limited. Thus, we also analyze the opportunities and challenges related to the formulation and application of bioproducts based on these bacteria. Key points •The mini-review updates the knowledge on Pseudomonas putida as a PGPR. • Some rhizosphere strains are able to improve plant growth under stress conditions. • The metabolic versatility of this species encourages the development of a bioproduct.
