“…Alike, P being a component of EO precursors (isopentyl diphosphate and dimethylallyl diphosphate) can also enhance EO production (Dehsheikh et al, 2020). The observed increase in EO yield reported in the current investigation might be attributed to the increased number of glandular trichomes and antioxidants, as some posterior studies have already claimed these factors are responsible for the increase in EO yield after combined treatment of plant beneficial microbes in MAPs like sweet basil (Gupta and Pandey, 2015) and Pelargonium graveolens L'Heŕ (Gupta et al, 2016).…”

Ocimum basilicum L. and its derived products are primarily consumed by humans; hence, agrochemical use seems inappropriate for its cultivation. However, farmers are accustomed to using rampant inorganic fertilizers to augment crop productivity, which has unintendedly engendered severe environmental perturbations. Concomitantly, farmers will soon have to confront the challenges of growing crops under suboptimal conditions driven by global climate change. Consequently, to develop a clean, sustainable, and resilient production technology, field experiments spanning over two years (2020 and 2021) were conducted, comprising three biostimulants, viz., vermicompost (0, 4, and 8 Mg ha−1), biofertilizer (uninoculated and inoculated), and liquid seaweed extract (without and at 7 ml L−1) in the Indian western Himalaya for the first time. Soil health indicators, leaf photosynthetic pigments, gaseous exchange, mineral contents, essential oil (EO) quantity, and composition were evaluated. Soil microbial respiration (SMR), microbial biomass carbon (MBC), organic carbon (OC), dehydrogenase (DHA), alkaline phosphatase (ALP), and β-glucosidase activities were increased by 36.23, 83.98, 30.61, 42.69, 34.00, and 40.57%, respectively, when compared with the initial soil status. The net photosynthetic rate (Pn) was significantly increased with the highest (8 Mg ha−1) and moderate (4 Mg ha−1) vermicompost dosages by 13.96% and 4.56%, respectively, as compared with the unfertilized control (0 Mg ha−1). Likewise, the biofertilizer and seaweed extract also enhanced Pn by 15.09% and 10.09%, respectively. The crop’s key EO constituents, viz., methyl chavicol and linalool, were significantly improved with the highest and moderate vermicompost rates of 2.71, 9.85%, and 1.18, 5.03%, respectively. Similarly, biofertilization and seaweed application also boosted methyl chavicol and linalool by 3.29, 8.67%, and 1.93, 3.66%, respectively. In both years, significantly higher herbage (8.86 and 11.25 Mg ha−1) and EO yield (113.78 and 154.87 kg ha−1) were recorded with a congregate treatment of the highest vermicompost dose, biofertilizer, and liquid seaweed extract. In conclusion, the integrated use of biostimulants having complementary properties can sustainably maximize the quantity and quality of O. basilicum and concomitantly ameliorate soil health. This study can inspire scientific communities and industries to develop second-generation biostimulant products, delivering better sustainability and resilience for a renaissance in agriculture.

“…Endophytes are known to exert beneficial effect on plants by assisting in an adjustment of plant phenolic compound content and anti-oxidative systems in response to unfavorable conditions [15,16]. Anti-radical activity of certain medicinal plants is promoted by endophytic microorganisms [17]. Antibiotic treated S. nigra flowers were likely deprived of TPC-and ARA-promoting effect of endophytes leading to a significantly decreased TPC and ARA.…”

Accumulating scientific evidence suggests that medicinal plant-associated microbiota has a significant role in biosynthesis of pharmacologically relevant compounds. Suppression of S. nigra microbiota by an antibiotic treatment leads to a decreased emission of volatile terpenoids from S. nigra flowers and an altered metabolome of a host plant. However, it is not known if suppression of microbiota also affects an abundance of health promoting compounds and pharmacologically relevant properties of S. nigra. The present study reveals, that suppression of phyllospheric microbiota by an antibiotic treatment affects total phenolic content (TPC), anti-radical activity (ARA) and total flavonol content (Flav) of wild S. nigra flowers. Significance analysis of metabolites (SAM) performed using ultra high performance liquid chromatography-time of flight-masspectrometry (UHPLC-TOF-MS) based metabolomics data identifies pharmacologically relevant flavonols as metabolites discriminating between antibiotic treated and control flowers of S. nigra. Reported results substantiate need for a research investigating an effect of microbiota suppression on a biological activity of S. nigra flowers.

“…The maximum increase in withaferin A by 4.00 fold was recorded in BS_CC followed by 3.00 fold in both STR_CF and TH_CC treatments as compared to the control plants (Table 1). Recently, a study showed that application of plant growth promoting microbes significantly enhanced secondary metabolite content in medicinal and aromatic plants like Bacopa monnieri, W. somnifera and Pelargonium graveolens (Rajasekar and Elango 2011;Gupta et al 2015bGupta et al , 2016. Increase in antioxidant capacity in TH_CF could also be positively correlated with increased Withanolide A, a well known antioxidant molecule.…”

In the present investigation, metabolites of Streptomyces sp. MTN14 and Trichoderma harzianum ThU significantly enhanced biomass yield (3.58 and 3.48 fold respectively) in comparison to the control plants. The secondary metabolites treatments also showed significant augmentation (0.75-2.25 fold) in withanolide A, a plant secondary metabolite. Lignin deposition, total phenolic and flavonoid content in W. somnifera were maximally induced in treatment having T. harzianum metabolites. Also, Trichoderma and Streptomyces metabolites were found much better in invoking in planta contents and antioxidants compared with their live culture treatments. Therefore, identification of new molecular effectors from metabolites of efficient microbes may be used as biopesticide and biofertilizer for commercial production of W. somnifera globally.
