“…Beneficial microbes can play an important role in increasing yields of the crop, remove contaminants, inhibit pathogens, and produce novel substances. The growth stimulation by beneficial microbes can be a consequence of biological nitrogen fixation, production of plant growth regulators such as IAA, gibberellic acids, and cytokines, and biocontrol of phytopathogens through the production of antibiotic, antifungal, or antibacterial, Fe-chelating compounds, induction of acquired host resistance, enhancing the bioavailability of minerals (Kour et al 2019;Kumar et al 2019b;Yadav et al 2019a).…”

The phyllosphere referred to the total aerial plant surfaces (above-ground portions), as habitat for microorganisms. Microorganisms establish compositionally complex communities on the leaf surface. The microbiome of phyllosphere is rich in diversity of bacteria, fungi, actinomycetes, cyanobacteria, and viruses. The diversity, dispersal, and community development on the leaf surface are based on the physiochemistry, environment, and also the immunity of the host plant. A colonization process is an important event where both the microbe and the host plant have been benefited. Microbes commonly established either epiphytic or endophytic mode of life cycle on phyllosphere environment, which helps the host plant and functional communication with the surrounding environment. To the scientific advancement, several molecular techniques like metagenomics and metaproteomics have been used to study and understand the physiology and functional relationship of microbes to the host and its environment. Based on the available information, this chapter describes the basic understanding of microbiome in leaf structure and physiology, microbial interactions, especially bacteria, fungi, and actinomycetes, and their adaptation in the phyllosphere environment. Further, the detailed information related to the importance of the microbiome in phyllosphere to the host plant and their environment has been analyzed. Besides, biopotentials of the phyllosphere microbiome have been reviewed.

“…Komagataella phaffii has two key properties that make it an attractive expression host. First, it can grow to very high cell densities (>300 g/L of wet cells), and second, it can utilize methanol as a sole carbon source (Kumar et al., 2019; Liu et al., 2019). As discussed in Section 2.1.3, this latter characteristic is of particular interest for the PCAg industry since it allows for very strong induction of gene expression (Ergün et al., 2019).…”

Cellular agriculture is a rapidly emerging field, within which cultured meat has attracted the majority of media attention in recent years. An equally promising area of cellular agriculture, and one that has produced far more actual food ingredients that have been incorporated into commercially available products, is the use of cellular hosts to produce soluble proteins, herein referred to as precision cellular agriculture (PCAg). In PCAg, specific animal‐ or plant‐sourced proteins are expressed recombinantly in unicellular hosts—the majority of which are yeast—and harvested for food use. The numerous advantages of PCAg over traditional agriculture, including a smaller carbon footprint and more consistent products, have led to extensive research on its utility. This review is the first to survey proteins currently being expressed using PCAg for food purposes. A growing number of viable expression hosts and recent advances for increased protein yields and process optimization have led to its application for producing milk, egg, and muscle proteins; plant hemoglobin; sweet‐tasting plant proteins; and ice‐binding proteins. Current knowledge gaps present research opportunities for optimizing expression hosts, tailoring posttranslational modifications, and expanding the scope of proteins produced. Considerations for the expansion of PCAg and its implications on food regulation, society, ethics, and the environment are also discussed. Considering the current trajectory of PCAg, food proteins from any biological source can likely be expressed recombinantly and used as purified food ingredients to create novel and tailored food products.

“…Mechanisms, such as the production of siderophore, 1-aminocyclopropane-1-carboxylate deaminase (ACC), volatile organic compounds and phytohormones, biofilm formation, signal interference, quorum sensing, etc., are used to bioremediate the polluted soil by PGPR [148]. Rhizoremediation is the combination of phytoremediation and bio-augmentation which can be applied for better results compared to any of the single approaches to eliminate or transform pollutants from the contaminated sites [149][150][151]. PGPR show symbiotic and non-symbiotic relationships with plants, which is essential for rhizoremediation [152].…”

Prospect and Challenges for Sustainable Management of Climate Change-Associated Stresses to Soil and Plant Health by Beneficial Rhizobacteria

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.
