“…However, the minor components of the essential oil were not significantly altered under the conditions of the experiment. In Borago officinalis L. (borage) foliar application of AgNPs (diameter ∼35 nm) was found to increase the phenol, tannin and alkaloid contents along with other vegetative and phytochemical properties, the most effective concentration being 0.6 mM [ 31 ]. Hydroponically grown Calendula officinalis L. (marigold) plants, when treated with 0.4 mM AgNPs (diameter 30–50 nm) and 100 mM methyl jasmonate (MeJa) showed 117% increase in saponin content but a decrease in anthocyanin and flavonoid contents [ 32 ].…”

Nanoparticles possess some unique properties which improve their biochemical reactivity. Plants, due to their stationary nature, are constantly exposed to nanoparticles present in the environment, which act as abiotic stress agents at sub‐toxic concentrations and phytotoxic agents at higher concentrations. In general, nanoparticles exert their toxicological effect by the generation of reactive oxygen species to which plants respond by activating both enzymatic and non‐enzymatic anti‐oxidant defence mechanisms. One important manifestation of the defence response is the increased or de novo biosynthesis of secondary metabolites, many of which have commercial application. The present review extensively summarizes current knowledge about the application of different metallic, non‐metallic and carbon‐based nanoparticles as elicitors of economically important secondary metabolites in different plants, both in vivo and in vitro. Elicitation of secondary metabolites with nanoparticles in plant cultures, including hairy root cultures, is discussed. Another emergent technology is the ligand‐harvesting of secondary metabolites using surface‐functionalized nanoparticles, which is also mentioned. A brief explanation of the mechanism of action of nanoparticles on plant secondary metabolism is included. Optimum conditions and parameters to be evaluated and standardized for the successful commercial exploitation of this technology are also mentioned.

Introduction: Water and nitrogen deficits are the most important limiting factors for plant growth and crop production in the world. Drought stress would be amplified by the global warming. Moreover, nitrogen scarcity is occurred in most arid and semi-arid areas. Cumin (Cuminum cyminum L.) is an important plant due to export benefits and low water demand. This study was aimed to evaluate nitrogen fertilizer effect on yield and some physiological characteristics of cumin under different irrigation regimens. Methods: The experiment was performed based on a split plot as randomized complete block design. Experiment treatments were irrigation regimens (field capacity, irrigation by draining 40% of soil water as middle stress, and irrigation by draining 80% of soil water as severe stress) and nitrogen fertilizers (60 kg ha-1 urea, 30 kg ha-1 urea, Nitroxin, and Nitroxin + 30 kg ha-1 urea). Results: Drought stress reduced cumin dry weight, seed yield, and chlorophyll content. In contrary, proline content, malondialdehyde (MDA) rate, phenol content, anthocyanin amount, and activity of catalase (CAT) and peroxidase (POX) increased by water stress. Increment urea use resulted in amending cumin growth and seed yield in the field capacity. Also, nitrogen use and raising its rate under the middle water stress caused to improve cumin drought tolerance. However, under the severe water stress, nitrogen application had not a significant impress on drought acclimation and seed yield. Conclusion: Nitroxin inoculation with use of 30 kg ha-1 urea was the most effective treatment to ameliorate seed yield and drought tolerance.
