“…In an experiment comparing ROS formation and antioxidant enzymes in C 3 and C 4 plants, Uzilday et al (2012) proposed that although the induction rate of antioxidant enzymes in C 4 plants was lower, their antioxidant system was more effective at coping with ROS formation under stress conditions. The study by Kandoi et al (2018) greater drought and salt resistance in C 4 plants (Figures 2 and 7b) (Gohil et al, 2022;Koetle et al, 2022;Wang et al, 2022). The L r of C 4 plants decreased more, but the DW p of C 4 plants decreased less than that of C 3 plants under drought and combined stresses, indicating better stress resistance in C 4 plants through the maintenance of aboveground growth (Kumar et al, 2014).…”

In nature, drought and salt stresses often occur simultaneously and affect plant growth at multiple levels. However, the mechanisms underlying plant responses to drought and salt stresses and their interactions are still not fully understood. We performed a meta‐analysis to compare the effects of drought, salt, and combined stresses on plant physiological, biochemical, morphological and growth traits, analyze the different responses of C3 and C4 plants, as well as halophytes and non‐halophytes, and identify the interactive effects on plants. There were numerous similarities in plant responses to drought, salt, and combined stresses. C4 plants had a more effective antioxidant defense system, and could better maintain above‐ground growth. Halophytes could better maintain photosynthetic rate (Pn) and relative water content (RWC), and reduce growth as an adaptation strategy. The responses of most traits (Pn, RWC, chlorophyll content, soluble sugar content, H2O2 content, plant dry weight, etc.) to combined stress were less‐than‐additive, indicating cross‐resistance rather than cross‐sensitivity of plants to drought and salt stresses. These results are important to improve our understanding of drought and salt cross‐resistance mechanisms and further induce resistance or screen‐resistant varieties under stress combination.

“…have been studied in recent years for their potential as biocontrol agents and for enhancing industrial enzyme production in extreme environments. [31][32][33][34][35] Metagenomic analysis indicated that the colonization of the microbial community in neem gum is a complex consequence and requires thorough investigation to understand the mechanism and guiding forces of colonization. In summary, it can be concluded that neem gum is a good source of diverse microorganisms which can have multiple agricultural and biotechnological applications.…”

Indian lilac or neem (Azadirachta indica) is found in tropical and subtropical regions of the Indian subcontinent. Each part of the tree is a source of various phytochemicals. Neem gum is an exudate from mature parts of the plant stem. Biochemically, it has an acidic pH range (5–6) and is composed of monosaccharides, saponins, phenols, and tannins. This study aimed to elucidate the diversity of neem gum-associated microflora through high throughput metagenomics approach using 16S rRNA variable region sequencing. The bacterial community of neem gum was dominated by Firmicutes (~82%), Proteobacteria (~18%), and Actinobacteria (~0.02%). Among the genera, Lactococcus was found to be the most dominant bacterium. The predominance of Lactococcus in neem gum is probably due to its acidic nature, which provides a suitable microenvironment for its proliferation. In addition, Lactococcus and beneficial microorganisms such as Pseudomonas, Burkholderia, Pantoea, Klebsiella, and Methylobacterium were also present in the gum. This study highlights the fact that neem gum can be exploited as a unique source of microorganisms for biotechnological and agricultural applications.

“…As a result, the current global scenario emphasizes the importance of adopting eco-friendly agricultural practices for long-term and high-quality food production [1]. Furthermore, to address the issue of declining soil fertility caused by synthetic fertilizers and pesticides, it is urgently necessary to establish a viable solution for nutrient maintenance in soil by effective microorganisms utilizing the organic resources for agricultural crops [2,3]. Sustainable environmentally friendly farming practices, such as organic farming, forego the use of synthetic fertilizers and pesticides in lieu of the use of biofertilizers, which enhance and maintain the soil's nutrient levels [4].…”

“…It is made by combining five major cow by-products: dung, urine, milk, curd, ghee, and other ingredients. Such bio-stimulants contains distinct macro and micronutrients, amino acids, and growth-promoting substances, in addition to beneficial microorganisms that boost in the production of high-quality crop yields [2,10]. To improve soil fertility, earthworm quality, and crop health, this bioformulation can be applied as a liquid manure at minimal expense, and it has been shown to increase plant growth and nutrient uptake while reducing biotic and abiotic stresses in crop plants.…”

Due to the alarming effect of synthetic and chemical-based agriculture on human health and the environment, organic farming has been receiving increasing attention around the world. Panchagavya (PG) and farmyard manure play crucial roles in organic farming's nutrient management. Despite its known potential in crop applications, Panchagavya microbial profile has yet to be mapped. The aim of this study is to unveil the succession of bacterial communities in Panchagavya during the fermentation process using targeted amplicon analysis. The results revealed that 45 phyla, 92 classes, 168 orders, 333 families, 899 genera, and 2026 species were obtained from all samples, along with 5144 OTUs. Proteobacteria (36.61-70.98%) and Bacteroidetes (14.59-23.81%) were found in greater abundance in all samples, with Proteobacteria being the most common in all samples, followed by Bacteroidetes and Firmicutes (12.67-29.58%). Pseudomonas was a dominant member of the fermentation process, along with Romboutsia, Paeniclostridium, Clostridium, Enterococcus, Lactobacillus, Bifidobacterium, and Ruminococcus. The findings indicate that Panchagavya demonstrates effectiveness as a fertilizer due to its inclusion of advantageous microorganisms and growth stimulants for plants. Furthermore, some bacterial members that have not yet been characterized for any role in the soil and plant systems, urging a comprehensive investigation into the potential functions for future agricultural applications and practices.
