“…In fact, an incremental pigment production has already been reported for the diazotrophic cyanobacteria Nostochopsis lobatus upon supplementation with phosphorous and iron [28]. The alteration of chlorophyll production at the genetic level in terrestrial N. antarctica LEGE13457 can also be associated with rare earth oxide nanoparticles; for instance, it has been demonstrated that low cerium concentrations can act as catalysts in chlorophyll production [29]. Moreover, this strain originates from the Victoria Valley, Antarctica (Table 1), where the environment is harsh.…”

In this study, five cyanobacteria strains (Alkalinema aff. pantanalense LEGE15481, Cyanobium gracile LEGE12431, Nodosilinea (Leptolyngbya) antarctica LEGE13457, Cuspidothrix issatschenkoi LEGE03282 and Leptolyngbya-like sp. LEGE13412) from the Blue Biotechnology and Ecotoxicology Culture Collection (LEGE CC) of CIIMAR were explored for their biotechnological potential in the treatment of psoriasis. Different extracts were characterized for their pigment profile by HPLC-PDA. The antioxidant potential of the extracts was assessed against the superoxide anion radical (O2•-). Their anti-inflammatory and antiproliferative potential was assessed in vitro using the macrophages RAW 264.7 and the human keratinocytes HaCaT as cell-line models, respectively. Terrestrial and freshwater strains presented the highest carotenoid content (33193−63926 μg/g dry extract), with all-trans-β-carotene, zeaxanthin, echinenone and lutein derivatives being the most abundant carotenoids. Acetone was the most effective solvent for pigment extraction. The acetone extracts presented the lowest IC50 values (0.29−0.38 mg dry extract/mL) regarding O2•- scavenging, and revealed anti-inflammatory potential, with N. antarctica LEGE13457, A. pantanalense LEGE15481 and Leptolyngbya-like sp. LEGE13412 reducing the nitric oxide (NO) in RAW 264.7 cell culture medium in about 25% (p < 0.05). With the exception of A. pantanalense LEGE15481, all the extracts significantly reduced keratinocyte proliferation (p < 0.05), demonstrating a selective toxicity among the different cell lines. Overall, Leptolyngbya-like sp. LEGE13412 and N. antarctica LEGE13457 seem promising for further exploitation in the framework of psoriasis, due to their antioxidant, anti-inflammatory and antiproliferative potential.

“…Seed germination phenomenon and early growth are the crucial developmental phases in the life cycle for the prosperous establishment and performance of plants (Moghanloo et al 2019a;Babajani et al 2018;Seddighinia et al 2020). Many factors influence the onset and progression of seed germination; the germination process is very sensitive to environmental factors such as heavy metals and nanoparticles (Seneviratne et al 2017;Jahani et al 2019).…”

This study aimed to investigate the interaction effects of iron oxide nanoparticle (nα-Fe 2 O 3) and its bulk counterpart (bα-Fe 2 O 3) with and/or without citrate interaction on germination and seedling growth of Oenothera biennis L. We prepared buffered suspensions of nα-Fe 2 O 3 and bα-Fe 2 O 3 at 4 levels (0, 0.2, 0.5 and 1 g.L −1). The nα-Fe 2 O 3 increased 89.17% germination percentage, 53.36% germination tolerance index, 82.21% root tolerance index, and 79.42% ferric reducing antioxidant power. The nα-Fe 2 O 3 +citrate improved α-Fe 2 O 3 function with a 47% relative hypocotyl length, and 97.32% vigor index2 increase. Leaf area, tolerance index of seedling fresh weight increased at bα-Fe 2 O 3 +citrate. Antioxidant enzyme activities are increased in α-Fe 2 O 3 +citrate, through which increased biomass and tolerance indices. Oxidative stress control was an important component of this plant's ability to withstand environmental stress and to succeed in germination and seedling growth. This finding emphasizes that if nα-Fe 2 O 3 were used at low and intermediate concentrations, it would not have toxic effects on this plant, and potentially would result in successful stress tolerance and could act as iron fertilizers for the growth of Oenothera biennis L. Abbreviations: AC (allometric coefficient); bα-Fe 2 O 3 (bulk α-Fe 2 O 3); CAT (catalase); Cit (citrate); Control (deionized water); FRAP (ferric reducing antioxidant power); FGP (final germination percentage); GP (germination percentage); GR (germination rate); GTI (germination tolerance index); HL (hypocotyl length); IONP (iron oxide nanoparticle); LA (leaf area); MDA (malondialdehyde); nα-Fe 2 O 3 (α-Fe 2 O 3 nanoparticle); POD (peroxidase); RHL (relative hypocotyl length); RL (root length); RSG (relative seed germination); RTI (root tolerance index); SOD (superoxide dismutase); TIFW (tolerance index of seedling fresh weight); TISL(tolerance index of seedling length), and VI (vigor index).

“…Depending on their physicochemical characteristics, the NMs can modify the different metabolic processes of plants. Photosynthetic efficiency can be improved through some NMs [127] , or overproduction of free radicals can be generated that will result in oxidative stress [113] , [114] , [120] , [122] . In the first case, the observed effect will be a higher biomass production or plant yield, while in the second case, the opposite effect can be observed.…”

The damage caused by an excessive concentration of free radicals is mitigated by the antioxidant defense system, increasing the production of enzymatic and non-enzymatic compounds ( Fig.…”
