“…While the spread of chilli root affected water and nutrition absorption of the plant. This study was in line with Kumari et al (2018) who found that both the identified species P. aeruginosa BHU B13-398 and B. subtilis BHU M were found to enhance most of the growth characteristics associated with PGPR including phosphate solubilization, IAA, ammonia, siderophore, and HCN production. Gechemba et al (2015) reported that the species of Pseudomonas and Bacillus have the potential for phosphate solubilization, IAA production, and siderophore activity.…”

“…Plants use these osmolytes to cope up with the stress conditions by employing different mechanisms such as change in cell osmotic pressure, contribution in reactive oxygen species (ROS) detoxification, assurance of membrane respectability and adjustment of compounds/proteins (Ashraf and Foolad, 2007; Hayat et al, 2012). Among them, the aggregation of L-proline upon osmotic pressure are all around seen in an enormous number of various creatures, comprising protozoa (Poulin et al, 1987; Inbar et al, 2013), eubacteria (Csonka, 1989; Verbruggen et al, 1993; Otvos et al, 2018), marine invertebrates (Burton, 1991; Sperstad et al, 2011), and algae (Brown and Hellebust, 1978; Liang et al, 2013; Kumari et al, 2018a, b), as well as in various plant species (Nakashima et al, 1998; Mattioli et al, 2008; Székely et al, 2008; Chun and Chandrasekaran, 2018). Besides acting as an osmolyte, L-proline additionally assumes significant character throughout stress as a metal chelator and an antioxidative defense molecule.…”

BackgroundIn response to various environmental stresses, many plant species synthesize L-proline in the cytosol and accumulates in the chloroplasts. L-Proline accumulation in plants is a well-recognized physiological reaction to osmotic stress prompted by salinity, drought and other abiotic stresses. L-Proline plays several protective functions such as osmoprotectant, stabilizing cellular structures, enzymes, and scavenging reactive oxygen species (ROS), and keeps up redox balance in adverse situations. In addition, ample-studied osmoprotective capacity, L-proline has been also ensnared in the regulation of plant improvement, including flowering, pollen, embryo, and leaf enlargement.Scope and conclusionsAlbeit, ample is now well-known about L-proline metabolism, but certain characteristics of its biological roles are still indistinct. In the present review, we discuss the L-proline accumulation, metabolism, signaling, transport and regulation in the plants. We also discuss the effects of exogenous L-proline during different environmental conditions. L-Proline biosynthesis and catabolism are controlled by several cellular mechanisms, of which we identify only very fewer mechanisms. So, in the future, there is a requirement to identify such types of cellular mechanisms.

“…For example, in wild-type tobacco plants, salicylic acid (SA) accumulation is essential for the mechanism of SAR, whereas transgenic tobacco plants do not show SAR expressions because of having salicylate hydroxylase gene of Pseudomonas putida, which causes constitutive expression of nahG gene [22]. ISR by Pseudomonas fluorescens WCS417r has been shown to be independent of SA accumulation in transgenic Arabidiopsis thaliana, which constitutively expresses nahG gene, but a response to ethylene or jasmonic acid (JA) is essential for the expression of ISR [23,24].…”

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.
