“…They also reduce water infiltration and hence prevent soil erosion [94]. Biofilmed biofertilizers (BFBFs) prepared with microbial consortia have proved to be a sustainable means of increasing crop yield [95]. Addition of cyanobacteria into areas undergoing desertification was found to stimulate biocrust formation, which improved soil properties and triggered plant succession [96].…”

Microalgae have been identified to produce a plethora of bioactive compounds exerting growth stimulating effects on plants. The objective of this study was to investigate the plant-growth-promoting effects of three selected strains of eukaryotic green microalgae. The biostimulatory effects of two Chlorella species (MACC-360 and MACC-38) and a Chlamydomonas reinhardtii strain (cc124) were investigated in a Medicago truncatula model plant grown under controlled greenhouse conditions. The physiological responses of the M. truncatula A17 ecotype to algal biomass addition were characterized thoroughly. The plants were cultivated in pots containing a mixture of vermiculite and soil (1:3) layered with clay at the bottom. The application of live algae cells using the soil drench method significantly increased the plants’ shoot length, leaf size, fresh weight, number of flowers and pigment content. For most of the parameters analyzed, the effects of treatment proved to be specific for the applied algae strains. Overall, Chlorella application led to more robust plants with increased fresh biomass, bigger leaves and more flowers/pods compared to the control and Chlamydomonas-treated samples receiving identical total nutrients.

“…The reduced number of seedlings may be explained by the high density of inoculated bacteria at the beginning of seed germination, given that seedlings are a vulnerable stage in plant development ( Nelson, 2018 ). Additionally, at early germination stages, the high density of microbes may compete for the available nutrients in the soil ( Kozdrój et al, 2004 ; Zakeel and Safeena, 2019 ). Since hybrids were differentially affected by SynCom inoculation, it is more likely that plant genetic background and plant-SynCom crosstalk might have been involved.…”

Modulating Drought Stress Response of Maize by a Synthetic Bacterial Community

Plant perception and responses to environmental stresses are known to encompass a complex set of mechanisms in which the microbiome is involved. Knowledge about plant physiological responses is therefore critical for understanding the contribution of the microbiome to plant resilience. However, as plant growth is a dynamic process, a major hurdle is to find appropriate tools to effectively measure temporal variations of different plant physiological parameters. Here, we used a non-invasive real-time phenotyping platform in a one-to-one (plant–sensors) set up to investigate the impact of a synthetic community (SynCom) harboring plant-beneficial bacteria on the physiology and response of three commercial maize hybrids to drought stress (DS). SynCom inoculation significantly reduced yield loss and modulated vital physiological traits. SynCom-inoculated plants displayed lower leaf temperature, reduced turgor loss under severe DS and a faster recovery upon rehydration, likely as a result of sap flow modulation and better water usage. Microbiome profiling revealed that SynCom bacterial members were able to robustly colonize mature plants and recruit soil/seed-borne beneficial microbes. The high-resolution temporal data allowed us to record instant plant responses to daily environmental fluctuations, thus revealing the impact of the microbiome in modulating maize physiology, resilience to drought, and crop productivity.

“…They live side by side, interacting with each other and with plants. These interactions can benefit plants, such as N-fixing bacteria and P-solubilizing microbes, etc., or be harmful, such as soil-borne disease-causing microbes [10,40]. The microbial biofilm formed in the root systems is an access point for associating multiple kingdoms that include microbial groups [11].…”

“…The diversity of soil microorganisms contributes significantly to sustainable farming. Diverse soil microorganisms play multiple roles in developing the soil's structural properties and enhancing its fertility [10]. Microorganisms in the soil stimulate crop growth by mobilisation nutrients in the soil, producing different growth regulators, increasing stress tolerance, stabilizing soil structure, and enhancing organic matter content and soil health.…”

The increase in temperature due to global warming leads to a rise in abiotic and biotic stresses for plants. Biofilms can aid plants in overcoming multiple environmental stresses. The purpose of this article is to examine biofilm technology, mechanisms, and efficacy in assisting plant performance under multiple stresses. The methodology used to write this literature review is based on references that can be accessed online via Science Direct, Google Scholar, scopus.com, and other sources. The results demonstrated that interaction between plants and microorganisms in the rhizospheres could aid plants in coping with environmental stress caused by the formation of a biofilm on the root surface by a consortium of microorganisms in the rhizosphere. Biofilm provides numerous benefits for plants, including improved soil health, protection from pathogens, promotion of plant growth, assistance with nutrient absorption, decreased use of inorganic fertilizer, and increased environmental tolerance. Biofilm technology is a promising soil management strategy for assisting plant adaptation to environmental stresses, enhancing plant growth and productivity, and promoting soil health.
