“…However, it is known that numerous legume nodule-forming symbiotic bacteria, such as effective strains of the genera Rhizobium , Bradyrhizobium , Sinorhizobium , Mesorhizobium , as well a group generically identified as beta-rhizobia and non-nodulating bacterial genera such as Azoarcus , Gluconacetobacter diazotrophicus , Azotobacter , Azospirillum , Paraburkholderia , Enterobacter , Pseudomonas, and Herbaspirillum , among others, stand out for their ability to fix atmospheric nitrogen and/or secrete bioactive compounds are commonly used as bioinoculants [ 56 ]. In addition, several worldwide studies have reported the use of microorganisms formulated as bioinoculants for plant growth promotion in a wide range of crops under field conditions, such as sugarcane, rice, soybean, bean, chickpeas, tomatoes, maize, tropical fruits, and wheat, among others [ 12 , 79 , 114 , 115 , 116 , 117 , 118 ].…”

Agricultural systems are highly affected by climatic factors such as temperature, rain, humidity, wind, and solar radiation, so the climate and its changes are major risk factors for agricultural activities. A small portion of the agricultural areas of Brazil is irrigated, while the vast majority directly depends on the natural variations of the rains. The increase in temperatures due to climate change will lead to increased water consumption by farmers and a reduction in water availability, putting production capacity at risk. Drought is a limiting environmental factor for plant growth and one of the natural phenomena that most affects agricultural productivity. The response of plants to water stress is complex and involves coordination between gene expression and its integration with hormones. Studies suggest that bacteria have mechanisms to mitigate the effects of water stress and promote more significant growth in these plant species. The underlined mechanism involves root-to-shoot phenotypic changes in growth rate, architecture, hydraulic conductivity, water conservation, plant cell protection, and damage restoration through integrating phytohormones modulation, stress-induced enzymatic apparatus, and metabolites. Thus, this review aims to demonstrate how plant growth-promoting bacteria could mitigate negative responses in plants exposed to water stress and provide examples of technological conversion applied to agroecosystems.

Temperature, rain, humidity, wind, and solar radiation are all climatic factors that affect agricultural activities. While some agricultural areas of the world are irrigated, the vast majority rely on natural rainfall patterns. Farmers will consume more water as a result of climate change and experience less water availability, resulting in a decrease in production capacity. As one of the most important natural phenomena affecting agricultural productivity, drought is a limiting environment for plant growth. Bacteria have been shown to reduce water stress in these plant species and promote greater growth by regulating gene expression and the integration of hormones. Phytohormones modulation, stress-induced enzymatic apparatus, and metabolites are integrated into the root-to-shoot phenotypic changes in growth rate, architecture, hydraulic conductivity, water conservation, plant cell protection, and damage restoration. By demonstrating how plant growth-promoting bacteria can mitigate plant stress and provide examples of technology conversion in agroecosystems, this review illustrates how water stress can be mitigated.

“…The first microbial inoculants used in agriculture were introduced by Nobbe and Hiltner (1895), who introduced "Nitragin," which contains rhizobia. In addition, numerous studies have examined the use of microorganisms as bioinoculants for the promotion of plant growth in sugarcane, rice, soybeans, beans, chickpeas, tomatoes, maize, tropical fruits, and wheat, among others [12,79,[114][115][116][117][118]. A rapid increase in farmers' adoption of bioinoculants has been observed [12], leveraging innovation and technologies to fulfill the growing demand for bioproducts.…”
