Effects of Bacillus subtilis on some physiological and biochemical parameters of Triticum aestivum L. (wheat) under salinity

Bacillus subtilis ameliorates water stress tolerance in maize and common bean

“…As previously mentioned, PGPR release phytohormones directly in plant cells or in the rhizosphere and stimulate the plant growth (Numan et al 2018). According to Lastochkina et al (2017), B. subtilis promotes plant growth and increases plant stress tolerance through of direct and indirect ways, such as synthesis of siderophores and/or plant hormones and improvement of nutrient availability. Furthermore, it is related that plants associated with PGPR display better relative water content, especially in abiotic stress situations (Parray et al 2016;Enebe and Babalola 2018).…”

“…Nutrient acquisition, synthesis of phytohormones, production of siderophore and improvement of antioxidant system are direct mechanisms performed by PGPR (Parray et al 2016). Indirectly, PGPR can stimulate plant growth by triggering the plant immune system against phytopathogens (Lastochkina et al 2017;Numan et al 2018). In addition, PGPR play important roles on plant physiology, including the amelioration of abiotic stress responses (Figueiredo et al 2008;Islam et al 2015).…”

Effects of Endophytic Bacillus Subtilis and Salicylic Acid on Postharvest Diseases (Phytophthora infestans, Fusarium oxysporum) Development in Stored Potato Tubers

“…), one of the earliest responses of plant cells to pathogens infection, which induce range of defense responses in plants, including the synthesis of a whole spectrum of protective compounds [13,19,39,44,45,47]. If ROS production increases dramatically, as occurs under environmental stresses, hydroxyl radical reacts with membrane lipids, inducing their peroxidation-the final product of which is MDA [13,25,53]. Thus, the development of the protective reactions of a plant organism to pathogens can be assayed by the degree of MDA accumulation.…”

“…Due to the fact that as the most optimal treatments for the simultaneous suppression of late blight and fusarium were determined to be 10 8 CFU/mL (for strains 10-4 and 26D), 10 7 CFU/mL (for strain 10-4 + SA) and 10 6 CFU/mL (for strain 26D + SA) further microbiological, molecular, and physiological-biochemical studies would continue to use these established concentrations. Colonization of the internal tissues of plants by bacteria is one of the most important indicators of their endophytic properties and a factor influencing biological activity in plant-microbial relationships [25,43]. Using the prints of slices of surface sterilized tubers and quantitative accounting (titer B. subtilis), it was experimentally shown that B. subtilis 10-4 and 26D, when applied immediately prior to storage, effectively penetrate the internal tissues of the tubers and colonize them from the inside ( Figure 4A).…”
