“…One of the best-known mechanisms to improve plant growth and development by PGPM is the modification of the level of antioxidants including antioxidative enzymes, e.g., superoxide dismutase (SOD), ascorbate peroxidase (APX), peroxidase (POD), catalase (CAT), glutathione reductase (GR), and non-enzymatic antioxidants, e.g., proline, glutathione (GSH), ascorbic acid, carotenoids, and phenolics [25,[273][274][275][276][277]. Islam et al [278] demonstrated that inoculation of Vigna radiata (L.) R. Wilczek with Bacillus cereus Pb25 increased dry biomass and yield in salt stress conditions.…”

“…A potato co-inoculated with T. viride and plant pathogen Alternaria solani showed improved redox homeostasis via increased activity of CAT and SOD, and enhanced concentration of free phenolics. Moreover, co-inoculation with T. viride and A. solani resulted in increased H 2 O 2 production which induced the expression of plant defense genes [274]. Chen et al [25] reported increased salt stress tolerance in maize after inoculation with B. amyloliquefaciens SQR9.…”

In the face of climate change, progressive degradation of the environment, including agricultural land negatively affecting plant growth and development, endangers plant productivity. Seeking efficient and sustainable agricultural techniques to replace agricultural chemicals is one of the most important challenges nowadays. The use of plant growth-promoting microorganisms is among the most promising approaches; however, molecular mechanisms underneath plant–microbe interactions are still poorly understood. In this review, we summarized the knowledge on plant–microbe interactions, highlighting the role of microbial and plant proteins and metabolites in the formation of symbiotic relationships. This review covers rhizosphere and phyllosphere microbiomes, the role of root exudates in plant–microorganism interactions, the functioning of the plant’s immune system during the plant–microorganism interactions. We also emphasized the possible role of the stringent response and the evolutionarily conserved mechanism during the established interaction between plants and microorganisms. As a case study, we discussed fungi belonging to the genus Trichoderma. Our review aims to summarize the existing knowledge about plant–microorganism interactions and to highlight molecular pathways that need further investigation.

“…The ISR defense system has gained substantial attention as a valuable response in plants when plants show elevated defensive capacity with respect to external elicitors. Jasmonic acid and ethylene are the key components of ISR expressed when plants treated with PGPM induce defense-related enzymes, for instance, phenylalanine ammonia-lyase (PAL) and pathogenesis-related (PR) proteins [ 49 ], and ROS-scavenging enzymes such as SOD and CAT, along with the synthesis of phenols and flavonoids, which prevent infection incited by phytopathogens [ [50] , [51] , [52] ].…”

“…Reactive oxygen species (ROS) play critical a role in cellular necrosis, apoptosis, migration, differentiation, and proliferation. Low to intermediate levels of ROS and reactive nitrogen species (RNS) are required for the upkeep of various important gene factor regulation, redox homeostasis, and physiological function (Kumar et al, 2022; Zehra et al, 2021). High levels of ROS formation, on the other hand, are accountable for interrupted redox homeostasis, which leads to oxidative stress and ROS‐directed damage to all valuable biomolecules including, DNA, proteins, and membranes (Jomova et al, 2023; Meena, Prasad, & Upadhyay, 2016; Meena, Zehra, Dubey, Aamir, et al, 2016; Meena, Zehra, Dubey, & Upadhyay, 2016).…”

Euphorbia neriifolia (EN) is a medicinal plant used to treat a variety of ailments in traditional systems. Despite numerous studies on pharmacological activities, no information was available on the microscopic study of this plant. This is the first study that has been attempted to fill this need by performing the light and field emission scanning electron microscopy (FESEM) of leaf, stem, and latex. The powder microscopy of several organs (leaves, stem, and bark) and exudate (latex) of EN was carried out using safranine, fast green, phloroglucinol, and other standard solutions at different magnifications. The chemical fingerprinting of petroleum ether extract was accomplished by using thin layer chromatography. The optimization of total lipid content from the EN leaf under ultrasound‐assisted extraction (UAE) and soxhlet extraction (SE) procedure was determined using response surface methodology (RSM). The studied factors that affect the lipid content were: solvent ratio, extraction temperature, and extraction time. Several notable characteristics observed in the leaf of EN are amphistomatic leaves with anticlinical cell walls, anomocytic stomata, spongy mesophyll cells, elongated palisade cells, angular collenchyma, and U‐shaped vascular bundle. The plano‐convex midrib is covered by polygonal to oval‐shaped cuticles and contains anomocytic stomata. The circular petiole has no trichomes and contains laticifers, crystals, and idioblasts. The circular stem was observed with trichomes, hypodermis, collenchyma, parenchymatous cells, central pith, pentagonal stellar region, cambium, and 2–4 times more xylem that of phloem. All of the powdered plant parts and exudate under study contained trichomes, xylem vessels, wood fibers, cork cells, starch grains, calcium oxalate crystals, idioblasts, lignified cork, tannin content, stone cells, and oil globules. The blackish‐green colored petroleum ether extract with semi‐solid consistency showed the greatest percent (%) yield of 4% in the latex of EN. The thin layer chromatography (TLC) examination of petroleum ether extract of EN leaf produced a maximum 6 spots with Rf values of 0.16, 0.58, 0.62, 0.73, and 0.96 in the mobile phase of petroleum ether‐acetone (8:2). In terms of optimization, the dark green colored UAE extract with semi‐sticky consistency showed highest % yield of 4.5% whereas the yellowish green colored SE extract of sticky consistency showed the highest % yield of 4.9%. The findings showed that there were not many differences in the total lipid content between UAE (0.16%) and SE (0.11%). However, the best optimum condition for lipid content extraction analysis was obtained as follows: solvent ratio (PE:HE) 50:50, extraction temperature 50°C, extraction time 45 min for UAE, and solvent ratio (PE:HE) 60:40, extraction temperature 45°C, and extraction time of 24 h for SE. Hence, this study signifies the various noteworthy microscopic features along with the presence of different phytocompounds through TLC and best optimized condition for the extraction of lipids from different parts of EN. As no previous study has been reported, the outcomes obtained from the current study prove to be beneficial in the identification of species, quality control, and detection of any adulteration from the laboratory and commercial samples of EN.Research Highlights The percent yield was found to be maximum in latex extract (4%). The leaf pet ether extract was separated into 6 bands with different Rf values. The extracted compounds from Euphorbia neriifolia leaves were categorized into non‐polar heat tolerant. The highest total lipid yield (0.1119) was obtained at solvent ratios 60:40 of PE:HE (petroleum ether: petroleum hexane).
