“…Plant growth-promoting microbes support plants to tolerate abiotic stress (drought, Cd, temperature, etc.) by producing indole-3-acetic acid (IAA) and siderophores, solubilizing phosphate, reducing stress ethylene content by synthesis of 1-aminocyclopropane-1-carboxylate (ACC) deaminase, and producing antioxidant enzymes like catalse (CAT), superoxide dismutase (SOD) and ascorbic peroxidase (APX) to scavenge ROS and promote nutrient uptake [223,224]. Orozco-Mosqueda et al [225] discovered that the enzyme activity of ACC deaminase results I the production of ammonia and α-ketobutyrate, which, by reducing ACC levels, hinders excessive increases in the synthesis of ethylene under different stress environments, and it one of the most effective mechanisms to lead to plant tolerance to salt stress.…”

A large number of studies have indicated that plant community modulate the yield, improve growth and promote development of host plants, and among them rhizosphere growth-promoting bacteria play an important role in increasing crop yield. Bacteria benefit from the plant nutrients provided by the roots, but plants can benefit from their rhizobacteria as well. Rhizobia are considered as the most important candidate for plant growth promotion in comparison with rhizobacteria due to their endophytic nature and nitrogen fixing ability. They can also provide auxins which play a notable function in plant growth and plant-microbe interactions. Bacillus spp., the sporulating Gram-positive bacteria, have important roles in plant growth promotion and induction of systemic resistance. Pseudomonas are Gram-negative aerobic chemoheterotroph and are usually found in the environment. Streptomyces are important groups of soil bacteria from the actinomycetes family. Most of them are efficient rhizosphere and rhizoplane colonizers, and they can also be endophytes colonizing inner tissues of host plants. The present review aims to present the most up-to-date findings and results regarding the effects of plant growth promoting bacteria on yield of different crops, especially sorghum. Furthermore, the mechanisms of the actions of different bacteria briefly illustrated, aiming to present future needs to be addressed in sustainable crop production. Plant growth promoting rhizobacteria inoculation with different plants or treating plants with microbe-to-plant signal constituents can be an effectual technique to stimulate crop growth. They are also active in protecting crops from phytopathogens and environmental stress, plant pathogens and they have positive roles in nutrient cycling.

“…To mitigate the adverse effects of abiotic stress on plants, various strategies have been developed, such as the application of exogenous plant growth regulators, like gibberellins, auxins, and cytokinins [8], and the addition of biochar [9,10]. Another approach involves inoculating root-colonizing bacteria into plants, known for their ability to produce plant growth phytohormones [11,12]. Currently, there is growing interest among researchers in microorganisms that stimulate plant growth, driven by environmental concerns and the need for sustainable food production [13].…”

The consumption of lettuce is associated with an increased risk of ingesting nitrate, a naturally occurring and potentially harmful compound that can have adverse effects on human health. Hydroponic cultivation systems serve as effective tools for regulating nutrient solutions and nitrogen availability, which are essential for controlling nitrate levels. However, the techniques for reducing nutrient levels need to be appropriately calibrated based on lettuce growth responses and their interactions with the environment and growing conditions. Previous studies have demonstrated that plant probiotic actinomycetes can alleviate nutritional stress in various crops. However, there is a noticeable gap in research concerning the effects of actinomycetes on hydroponically grown lettuce, particularly under nutrient-limiting conditions. This study aimed to evaluate the effectiveness of the actinomycete Streptomyces thermocarboxydus S3 in enhancing lettuce growth in a nutrient-restricted hydroponic system. The results indicated that the detrimental effects of nutrient stress on lettuce were mitigated by the inoculation of lettuce with S. thermocarboxydus S3. This mitigation was evident in various growth parameters, including leaf count, shoot length, and the fresh and dry weights of both shoots and roots. In the presence of nutritional stress, S. thermocarboxydus S3 likely mitigated the negative effects on lettuce by reducing hydrogen peroxide levels, presumably through the synthesis of H2O2-scavenging enzymes. Furthermore, S. thermocarboxydus S3 successfully survived and colonized lettuce roots. Therefore, the inoculation of lettuce with S. thermocarboxydus S3 offers significant advantages for promoting lettuce growth in nutrient-limited hydroponic systems.
