“…Grafting is a widely used biotechnological tool in vegetable crops and is considered to be a rapid and effective method to protect plants against the effects of soil-borne pathogens (Rahman et al 2021), and enhance plant's resistance to various abiotic stresses, such as high temperature (De Oliveira et al 2020), drought (Luo et al 2020), salinity (Lo'ay and Abo E-Ezz 2021). In addtion, rootstock grafting can also improve the absorption of potassium (K) and magnesium (Mg) by plants (Huang et al 2013(Huang et al , 2016, and rootstock is the decisive factor for grafted plants to absorb mineral nutrients (Huang et N acquisition capacity may enable grafted-plants grow better with less N-fertilizer.…”

Background Excessive and insufficient application of N fertilizer can inhibit plant growth, reduce N-use efficiency (NUE) and lead to production reduction. Watermelon is an important crop that often restricted by inappropriate N supply. The study aims to test whether grafting with bottle gourd rootstock can improve NUE and growth performance of watermelon under low N and to clarify the underlying physiological mechanism. Methods Grafted (self-grafted and rootstock-grafted watermelon) and ungrafted (watermelon and bottle gourd) seedlings were tested respectively, and treated with 9 mM (normal condition) and 4 mM (low N condition) NO3--N concentrations for 18 days under hydroponic conditions.Results The growth and NUE of bottle gourd rootstock-grafted watermelon seedlings increased under low-nitrate, while decreased slightly in self-grafted seedlings compared with control. Rootstock-grafted plants had higher root morphological characteristics, NO3- uptake, photosynthesis, and NUE traits than self-grafted plants under low-nitrate. The expression of nitrate transporter genes NRT1.5 and NRT2.1, and N metabolizing enzyme genes NR, NiR, GS1 and GS2 of rootstock-grafted plants were significantly up-regulated at low-nitrate treatment, which may lead to increased NO3- uptake and metabolism.Conclusion The bottle gourd rootstock grafting can improve the growth and NUE of watermelon seedlings under low-nitrate treatment. The improved plant performance is attributed to the vigorous root systems and higher NO3- uptake of rootstock roots, and the enhanced N metabolism and photosynthetic capacity of scion leaves. Grafting with the bottle gourd rootstock may be beneficial to the efficient production of watermelon and economic application of N fertilizer.

“…However, the main contribution of PGPR to agroecological systems is N 2 fixation, Psolubilization, antibiotic development, and secretion of related plant growth-promoting substances [8,58,59] (Figure 2). Countable encouraging studies have already shown that agronomic returns are dramatically increasing relative to the treatment of agricultural soils with PGPR inoculations [60][61][62]. The unlocking of the mechanism of BNF noticed the simultaneous performance of a complex enzyme called "nitrogenase" and Nif gene interactions [33,63].…”

“…PGPR are natural, economic, eco-friendly, biodegradable, and target-specific components asso-ciated with the plant root zone which offer protection against harmful pests directly or indirectly. The PGPR represents biocontrol properties against a wide range of soil-borne plant pathogens by producing siderophore, antibiotics, and HCN [8,59,62,156,157]. The identification and use of these beneficial microbes as biocontrol agents will reduce the use of toxic and hazardous chemical pesticides, and also decrease the problems associated with environmental pollution.…”

Climate change imposes biotic and abiotic stresses on soil and plant health all across the planet. Beneficial rhizobacterial genera, such as Bacillus, Pseudomonas, Paraburkholderia, Rhizobium, Serratia, and others, are gaining popularity due to their ability to provide simultaneous nutrition and protection of plants in adverse climatic conditions. Plant growth-promoting rhizobacteria are known to boost soil and plant health through a variety of direct and indirect mechanisms. However, various issues limit the wider commercialization of bacterial biostimulants, such as variable performance in different environmental conditions, poor shelf-life, application challenges, and our poor understanding on complex mechanisms of their interactions with plants and environment. This study focused on detecting the most recent findings on the improvement of plant and soil health under a stressful environment by the application of beneficial rhizobacteria. For a critical and systematic review story, we conducted a non-exhaustive but rigorous literature survey to assemble the most relevant literature (sorting of a total of 236 out of 300 articles produced from the search). In addition, a critical discussion deciphering the major challenges for the commercialization of these bioagents as biofertilizer, biostimulants, and biopesticides was undertaken to unlock the prospective research avenues and wider application of these natural resources. The advancement of biotechnological tools may help to enhance the sustainable use of bacterial biostimulants in agriculture. The perspective of biostimulants is also systematically evaluated for a better understanding of the molecular crosstalk between plants and beneficial bacteria in the changing climate towards sustainable soil and plant health.

“…Sowing cover crops acting as bio-fumigants is also an agricultural technique used against soil fungal pathogens with interesting results. Thus, Rahman et al [ 14 ] found that mustard plants grown in intercropping with tomato, and mowed at early flowering to be incorporated in the first 15 cm of topsoil, reduced the damage from Verticillium dahliae .…”

Many fungi, especially endophytes, have been found to produce multiple benefits in their plant hosts, with many of these benefits associated with the protection of plants against fungal diseases. This fact could be used in the development of new bio-products that could gradually reduce the need for chemical fungicides, which have been associated with multiple health and environmental problems. However, the utilization of the living organism may present several issues, such as an inconsistency in the results obtained and more complicated management and application, as fungal species are highly influenced by environmental conditions, the type of relationship with the plant host and interaction with other microorganisms. These issues could be addressed by using the bioactive compounds produced by the fungus, in cases where they were responsible for positive effects, instead of the living organism. Multiple bioactive compounds produced by fungal species, especially endophytes, with antifungal properties have been previously reported in the literature. However, despite the large amount of these metabolites and their potential, extensive in-field application on a large scale has not yet been implemented. In the present review, the main aspects explaining this limited implementation are analyzed, and the present and future perspectives for its development are discussed.
