“…The incorporation of nSe as a supplement in the culture medium influenced morphology, growth, anatomy, and development in a manner dependent on the applied dose and the Se form. Responses to the nSe exposure were partly distinct from that of BSe, in line with the findings of Babajani et al, [6] in Melissa officinalis and Sotoodehnia-Korani et al, in Capsicum annuum [7]. The nano-type Se (nSe) exhibited a higher efficiency to stimulate plant growth and organogenesis than the bulk form.…”

“…On the other hand, several lines of evidence highlighted risks associated with high concentrations of Se [6,7,11,12]. Moreover, recent reports point out the plant cell may differentially respond to the nano-based materials relative to the bulk counterparts [6,7,13]. The elemental red Se nano-substance (nSe) exhibits efficient antimicrobial properties, great bioactivity, considerable antioxidant capacity, and anti-proliferative effects [14].…”

To gain a better insight into the selenium nanoparticle (nSe) benefits/toxicity, this experiment was carried out to address the behavior of bitter melon seedlings to nSe (0, 1, 4, 10, 30, and 50 mgL-1) or bulk form (selenate). Low doses of nSe increased biomass accumulation, while concentrations of 10 mgL-1 and above were associated with stem bending, impaired root meristem, and severe toxicity. Responses to nSe were distinct from that of bulk in that the nano-type exhibited a higher efficiency to stimulate growth and organogenesis than the bulk. The bulk form displayed higher phytotoxicity than the nano-type counterpart. According to the MSAP-based analysis, nSe mediated substantial variation in DNA cytosine methylation, reflecting the epigenetic modification. By increasing the concentration of nSe, the expression of the WRKY1 transcription factor linearly up-regulated (mean = 7.9fold). Transcriptions of phenylalanine ammonia-lyase (PAL) and 4-Coumarate: CoA-ligase (4CL) genes were also induced. The nSe treatments at low concentrations enhanced the activity of leaf nitrate reductase (mean = 52%) in contrast with the treatment at toxic concentrations. The toxic concentration of nSe increased leaf proline concentration by 80%. The nSe supplement also stimulated the activities of peroxidase (mean = 35%) and catalase (mean = 10%) enzymes. The nSe-treated seedlings exhibited higher PAL activity (mean = 39%) and soluble phenols (mean = 50%). The nSe toxicity was associated with a disrupted differentiation of xylem conducting tissue. The callus formation and performance of the explants originated from the nSe-treated seedlings had a different trend than that of the control. This experiment provides new insights into the nSe-associated advantage/ cytotoxicity

“…To prepare enzyme extracts, the well‐powdered leaves in liquid nitrogen were homogenized using a phosphate buffer (0.1 M, pH 7.3) supplemented by ascorbate and Na 2 EDTA . Peroxidase activity was spectrophotometrically measured based on absorbance variations at 470 nm per min in the enzyme reaction mixture . In addition, the activity of catalase enzyme was determined according to the protocol of Dhindsa et al…”

“…Plenty of bioactive compounds are utilized as elicitors, such as H 2 O 2 , nitric oxide (NO), H 2 S, salicylic acid, jasmonic acid, chitosan, etc., to stimulate secondary metabolism in medicinal plants . Hence, treating seeds or tissue explants with cold plasma may offer an opportunity to reduce the risk of tissue contamination, accelerate seedling growth, and/or elicit production of secondary metabolites.…”

The plasma-primed seeds of Catharanthus roseus were cultured in a hormone-free culture medium under sterile conditions. Plasma of 30 or 60 s improved root length (mean = 41.4%) and biomass (mean = 47%), whereas plasma of 90 s delayed plant growth. The plasma treatments enhanced concentrations of photosynthetic pigments and soluble phenols. Plasma of 90 s increased the proline level. With a similar trend, plasma priming induced activities of phenylalanine ammonia-lyase, catalase (about twofold) and peroxidase (31%) enzymes. Plasma also upregulated the expressions of deacetylvindoline O-acetyltransferase gene by an average of 7.8 times. Similarly, the plasma-treated seedlings contained higher concentrations of alkaloids (mean = 72%). Here, molecular evidence is provided on the plasma-associated modifications in secondary metabolism.
