“…Additionally, these microbes can offer enhanced drought, moisture, and salinity tolerances, making them very appropriate for farming on marginal terrains [11]. They produce phytohormones, physiologically active substances, and some enzymes that can improve plant health and, productivity [12]. The use of endophytes as bioinoculants has the potential to improve crop production and lessen the need for artificial fertilisers and pesticides, providing a sustainable substitute for conventional farming methods [13,14].…”

Changing understanding of endophytes in the realm of agriculture suggests the possibility of improving soil health and productivity, as well as the overall environmental sustainability of agriculture. These non-pathogenic microorganisms living in a plant are capable of conferring stress tolerance, promoting growth, and suppressing pathogens. Nevertheless, navigating regulatory barriers and streamlining application techniques pose challenges. To maximize their agricultural utility, future research should focus on exploring new strains, optimizing application techniques, and integrating endophytes into crop breeding programs. Leveraging endophytes may further lead to the developing of sustainable agriculture and reduce many concerns related to global food security.

“…Rolli et al [16] indicated that beneficial bacteria rapidly and intimately colonize the rhizoplane and the root system of grapevine and can be successfully used to promote the growth of grapevines in the field. The use of PGPB in the form of biofertilizers or inoculants to reduce the application of fertilizers and pesticides, thereby improving the soil environment, and increase plant yield is currently a significant research area in the fields of agriculture, microbiology, and biotechnology [17]. However, few studies have combined organic fertilizers with PGPB to improve plant growth.…”

Plant growth-promoting bacteria (PGPB) have growth-promoting and disease-resisting effects and can be used as new types of plant growth promoters. This study was conducted to determine the plant growth-promoting traits of five strains and follow a 2-year field trial to evaluate their effects on grape growth and fruit quality. The five PGPB were combined with two organic fertilizers (cow dung fertilizer and distillers’ grain fertilizer) for application on grape fields; the control group only received the corresponding organic fertilizer. The five strains showed different growth promoting abilities, as indicated by their differing production of indole acetic acid (IAA) and siderophores and ability to dissolve phosphorus and potassium, fix nitrogen, and resist saline and alkali. During the field trial, vine growth and fruit quality were significantly better in the distillers’ grain fertilizer (high nutrient content) alone treatment than in the cow dung fertilizer (low nutrient content) alone treatment. However, after the two fertilizers were inoculated with the five different PGPB, only the five treatments with cow dung fertilizer inoculated with PGPB showed significant improvement. The five treatments of cow dung fertilizer inoculated with PGPB exhibited varied impacts on plant growth and fruit quality. And the promotion effects persisted significantly after two consecutive years. Among the PGPB, Bacillus velezensis 18, B. velezensis 20, and Rahnella aquatilis 5 emerged as consistently effective performers over the two-year period, demonstrating stable and commendable outcomes. These strains are recommended for prolonged application in grape cultivation to optimize growth and yield. This study provides a theoretical reference and an experimental basis for organic fertilizer inoculated with PGPB to improve grape production.

“…Plant growth promoting rhizobacteria (PGPR) represent a beneficial group of root-colonizing microorganisms that offer a natural approach to enhancing plant growth and health [1]. PGPR employ an array of mechanisms to foster plant growth including enhanced nutrient uptake, production of plant hormones, solubilization of insoluble minerals, nitrogen fixation, disease suppression, root growth promotion, improvement of soil structure and so on.…”

Plant growth-promoting rhizobacteria (PGPR) boost plant growth and agricultural sustainability in an ecologically friendly way. The cultivation of chrysanthemum, a globally significant flower crop, has relied heavily on substantial agrochemical inputs that have detrimental impact on the environment. To assess the potential of chrysanthemum rhizobacteria to reduce this reliance, bacterial strains were retrieved from the plant rhizosphere and subjected to an assessment of various plant growth-promoting traits. Out of the 34 rhizobacterial isolates, 21 demonstrated the production of the plant growth hormone auxin, 21 had phosphate solubilization ability, 22 were capable of nitrogen fixation, and 21 could produce ammonia. Based on these findings, seven preeminent PGPR strains, characterized by multifaceted plant growth-promoting traits, were selected for subsequent studies and identified as species belonging to Acinetobacter, Bacillus, Pantoea, Serratia and Staphylococcus. The selected strains were systematically analyzed for their capacity to endure an array of abiotic stresses. A majority of these strains demonstrated adaptation under osmotic stress ranging from -0.15 to -0.49 MPa, temperatures of 20°C and 30°C, and salt stress within the range of 3 to 7% NaCl, which suggests their potential to promote plant growth across diverse environmental conditions. Additionally, the secretion of hydrolytic enzymes such as protease, pectinase and amylase was examined, and only the Staphylococcus hominis PGPR-12 strain demonstrated the ability to produce all three extracellular hydrolases. These findings underscore the potential application of multiple isolates possessing promising plant-probiotic properties to enhance plant growth across various conditions, thereby necessitating further exploration through pot and field assays.
