“…which can also form biofilms on abiotic surfaces [31]. The formation of biofilms in plant roots and abiotic surfaces has also been reported for Rhizobium strains able to nodulate different legumes [32] and for Rhizobium and Phyllobacterium able to promote the growth of strawberry and spinach plants [16,26]. These strains produce cellulose and cellulases, which are involved in biofilm formation [32] and developed microcolonies typical of biofilm initiation in the roots of strawberry [26] and spinach plants [16].…”

“…In addition to having several in vitro plant growth promotion mechanisms, good PGPR must be able to colonize the plant roots because this is an essential step for growth promotion [25]. The ability to colonize the roots of different non-leguminous plants has been shown for Rhizobium strains in tomato and pepper [14], strawberry [26], lettuce and carrots [15] and spinach [16], for a Phyllobacterium strain in strawberry [17] and for Mesorhizobium strains in lettuce and carrots [27]. Within these vegetables, the tomato (Solanum lycopersicon L.) is highlighted, whose production exceeds that of the other mentioned vegetables worldwide (http://www.fao.org/faostat/en/#home).…”

Mesorhizobium contains species widely known as nitrogen-fixing bacteria with legumes, but their ability to promote the growth of non-legumes has been poorly studied. Here, we analyzed the production of indole acetic acid (IAA), siderophores and the solubilization of phosphate and potassium in a collection of 24 strains belonging to different Mesorhizobium species. All these strains produce IAA, 46% solubilized potassium, 33% solubilize phosphate and 17% produce siderophores. The highest production of IAA was found in the strains Mesorhizobium ciceri CCANP14 and Mesorhizobium tamadayense CCANP122, which were also able to solubilize potassium. Moreover, the strain CCANP14 showed the maximum phosphate solubilization index, and the strain CCANP122 was able to produce siderophores. These two strains were able to produce cellulases and cellulose and to originate biofilms in abiotic surfaces and tomato root surface. Tomato seedlings responded positively to the inoculation with these two strains, showing significantly higher plant growth traits than uninoculated seedlings. This is the first report about the potential of different Mesorhizobium species to promote the growth of a vegetable. Considering their use as safe for humans, animals and plants, they are an environmentally friendly alternative to chemical fertilizers for non-legume crops in the framework of sustainable agriculture.

“…There is a plethora of previous work showing the beneficial effects of rhizobial strains on the growth and development of several non-legume crops, such as sorghum, lettuce, carrots, spinach, tomato, pepper, strawberries, barley, wheat, rice, and cotton, amongst others, improving in most of these crops the quality of both the edible and non-edible parts [52][53][54][55][56][57][58][59][60]. The majority of these studies have shown the effects of these interactions only under laboratory-or greenhouse-controlled conditions.…”

The overgrowth of human population and the demand for high-quality foods necessitate the search for sustainable alternatives to increase crop production. The use of biofertilizers, mostly based on plant probiotic bacteria (PPB), represents a reliable and eco-friendly solution. This heterogeneous group of bacteria possesses many features with positive effects on plants; however, how these bacteria with each other and with the environment when released into a field has still barely been studied. In this review, we focused on the diversity of root endophytic rhizobial and non-rhizobial bacteria existing within plant root tissues, and also on their potential applications as consortia exerting benefits for plants and the environment. We demonstrated the benefits of using bacterial inoculant consortia instead of single-strain inoculants. We then critically discussed several considerations that farmers, companies, governments, and the scientific community should take into account when a biofertilizer based on those PPBs is proposed, including (i) a proper taxonomic identification, (ii) the characterization of the beneficial features of PPB strains, and (iii) the ecological impacts on plants, environment, and plant/soil microbiomes. Overall, the success of a PPB consortium depends on many factors that must be considered and analyzed before its application as a biofertilizer in an agricultural system.

Climate change poses a great threat to the sustainability in agricultural crop production. Such circumstances demand the use of improved agricultural practices, environment friendly and climate resilient technologies. Microorganisms, being ubiquitous and abundant in the soil environment, are the key players regulating the earth's biogeochemical systems. The enormous potential of these microbes is being recognized and scientific community around the globe is involved in significant research towards the selection and commercialization of the microbes of biotechnological and environmental relevance. These microbes may be helpful in sustainable crop production by providing protection to plants from harmful pests and pathogens, by enhancing plant growth, by alleviating environmental and nutritional stresses, thus facilitating plants to Chapter contents Introduction ……………………………………………………………………………………………………..
