“…Environmental stress can affect the survival, diversity of microbes, and plant growth-promoting microbes potential to improve plant growth and stress tolerance (Lopes et al 2021). This is observed in Brachiaria inoculated with Sarocladium implicatum.…”

“…Biostimulants are also beneficial in mitigating other effects of abiotic stresses, by increase the photosynthetic pigments, carbohydrates, proteins concentrations, and total biomass (Lopes et al, 2021), as related in Cicer arietinum L. (Khan et al, 2019) and Triticum aestivum L. (Singh et al, 2018) both under drought. Our results showed that the biostimulants attenuated the effect of shading by the accumulation of sugars, resulting in a higher concentration of starch, carbohydrate, and nitrogen, increasing biomass production.…”

“…These biostimulants can be used as an alternative to increasing shade tolerance in pasture plants. Plant growth-promoting rhizobacteria (PGPR) act as biostimulants enhancing nutrient uptake, modulating hormones, and mitigating the effects of biotic and abiotic stress (Lopes et al, 2021;Riaz et al, 2021). Biostimulants can mitigate the deleterious effects of shade in Solanum quitoense Lam.…”

“…Primary metabolites, such as amino acids, proteins, carbohydrates, and organic acids, guarantee the maintenance of cell reproduction and plant development (Mundim & Pringle, 2018, Wang et al, 2019. These osmoregulants increase plant tolerance against environmental stress conditions (Lopes et al, 2021), and shade reduced it is the concentration (Kooke & Keurentjes, 2012).…”

Shade is considered an abiotic stress factor which reduce the primary metabolism and restricts normal growth in forage grass in integrated systems. Biostimulants are beneficial in promoting growth and protecting plants against environmental stresses. This is the first study that links biostimulants and the primary metabolism of plants grown under contrasting light intensities. We investigated how the use of biostimulants modifies the primary metabolism, reducing the deleterious effects of shading in the development of tropical forage grass Brachiaria brizantha cv. BRS Piatã. The association of Pseudomonas fluorescens and Burkholderia pyrrocinia, inoculated by soil drench, were used as biostimulants. We measured leaf anatomy, plant growth, and biochemical parameters. The use of biostimulants increased the shade tolerance on B. brizantha by modifying leaf structure, increasing the chlorophyll content, and inducing the production of osmoregulants, such as carbohydrates and proteins. In turn, increasing the accumulation of primary metabolites, promoted root development, plant height, and leaf area, resulting in more vigorous plants with greater biomass production. These results suggested that forage grass can be protected from inhibitory effects of the shade stress by the biostimulants, and this would improve its survival and growth in integrated crop-livestock-forestry systems.

“…Such biofertilizers are available in both solid and liquid forms, and liquid formulations are found to be more effective. Liquid formulations are primarily of three types, i.e., root inoculation, seed inoculation and soil inoculation (Lopes et al, 2021). Upon applying Burkholderia phytofirmans biofertiliser to Ryegrass root, seed, and soil, soil inoculation method was most efficient in improving the production of plant biomass, phytoremediation and hydrocarbon degradation (Afzal et al, 2013).…”

A multitude of roles is played by microbes in food and agriculture that include nutrient cycling and management, organic matter decomposition and fermentation. Plant growth promoting rhizobacteria (PGPR), representing microbial groups and with ability of colonizing plant roots, influence plant growth through various indirect and direct modes in order to promote its growth and/or protect it from diseases or damage due to insect attack. Thus, PGPR research has received renewed interest worldwide. Increasing number of crop-specific PGPR are being commercialized these days. Approaches like seed-inoculation and soil application either alone or in combination with bacterial culture/product for increased nutrient availability through phosphate solubilisation, potassium solubilisation, sulfur oxidation, nitrogen fixation, iron, and copper chelation are gaining popularity. Arbuscular mycorrhizal fungi (AMF) are root fungal symbiont that improve management of abiotic stress such as phosphorus deficiency. PGPR involves roles like production of indole acetic acid (IAA), ammonia (NH3), hydrogen cyanide (HCN), catalase, etc. PGPR also improve nutrient uptake by altering the level of plant hormone that enhances root surface area by increasing its girth and shape, thereby helping in absorbing more nutrients. PGPR facilitate seed germination, seedling growth and crop yield. An array of microbes including Pseudomonas, Azospirillum, Azotobacter, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus, and Serratia enhance plant growth. Various Pseudomonas sp. have demonstrated significant increase in germination, seedling growth and yield in different agricultural crops, including wheat. Hence, developing a successful crop-specific PGPR formulation, the candidate should possess characteristics like high rhizosphere competence, extensive competitive saprophytic ability, growth enhancing ability, ease of mass production, broad-spectrum action, safety toward the environment and compatibility with other partnering organisms.

Land degradation and soil contamination have become global problem due to irresponsible anthropogenic activities and the overutilization of natural resources by humans. Land degradation and contamination due to toxic heavy metals have adversely impacted not only crop productivity but also the overall environmental health of our planet. Mitigation and management of polluted land are urgently required to achieve the goal of sustainable development because of the continuous human population explosion. In recent years, the biodiversity under phytoremediation is gaining scientists' attention for utilizing polluted lands and obtaining a bio‐based economy aimed at economically valuable and nonedible native plants. In the present review, we have focused on the biodiversity prospecting and phytoremediation potentials of economically important native plants, which may open up new horizons for sustainable development and redevelopment of polluted land sites.
