“…Nitric oxide (NO), as a gaseous small molecule, was proven to play significant roles in plant growth and development by an increasing number of recent studies ( Guo and Crawford , ; Besson‐Bard et al, ; Baudouin , ; Mur et al, ; Yu et al, ). Our previous research revealed that NO ameliorated zinc oxide nanoparticles‐induced phytotoxicity in rice seedlings ( Chen et al, ), and enhanced Na + sequestration and salt resistance of mangrove plants ( Chen et al, , , ). Whether NO can promote Se concentration of rice seedling roots under selenite supply was investigated in this study.…”

Our lab revealed that NO ameliorated zinc oxide nanoparticles‐induced phytotoxicity in rice seedlings ( Chen et al, ). In mangrove wetland plants, we also demonstrated that NO could enhance salt secretion and Na + sequestration in Avicennia marina ( Chen et al, ), mediate root K + : Na + balance in Kandelia obovata ( Chen et al, ), through enhancing the expressions of genes endcoding H + ‐ATPase, Na + /H + antiporter, and AKT1‐type K + channel.…”

Nitric oxide (NO) plays a key role in regulating a wide range of physiological and biochemical processes. This study investigated possible effects of NO, which was supplied by sodium nitroprusside (SNP), NO donor, on selenium (Se) concentration, Se species within roots, activities and gene transcription of selenite uptake, and metabolism‐related transporters or enzymes using ICP‐MS, HPLC‐ICP/MS, qRT‐PCR, fluorescence imaging, and biochemical analysis in the roots of rice (Oryza sativa L.) seedling. A suitable SNP concentration (10 µM) increased Se concentration in rice roots. NO enhanced the gene transcription of phosphate transporter OsPT2 and sulfate transporters OsSultr1;2 and OsSultr4;1 that contribute to selenite uptake. Furthermore, NO increased selenocysteine and methyl‐selenocysteine concentrations in roots, stimulated glutathione biosynthesis by up‐regulating the transcript levels of γ‐glutamylcysteine synthetase (γ‐ECS) and glutathione synthetase (GS), and increased cysteine synthase (CS) activity. In conclusion, our results indicate that NO promotes Se concentration of rice seedling roots by enhancing selenite uptake, up‐regulating gene transcription of selenite uptake‐related transporters, and increasing Se metabolism through regulating glutathione biosynthesis.

“…For instance, AgNP-induced phytotoxicity could be alleviated by NO in P. sativum seedlings (Tripathi et al, 2017). Correspondingly, O. sativa NO excess mutant (noe1) plants were tolerant to ZnONP treatment, whereas OsNOA1-silenced (noa1) plants were susceptible to ZnONP-induced phytotoxicity (Chen et al, 2015). …”

Nanoparticles Alter Secondary Metabolism in Plants via ROS Burst

2017

The particles within the size range of 1 and 100 nm are known as nanoparticles (NPs). NP-containing wastes released from household, industrial and medical products are emerging as a new threat to the environment. Plants, being fixed to the two major environmental sinks where NPs accumulate — namely water and soil, cannot escape the impact of nanopollution. Recent studies have shown that plant growth, development and physiology are significantly affected by NPs. But, the effect of NPs on plant secondary metabolism is still obscure. The induction of reactive oxygen species (ROS) following interactions with NPs has been observed consistently across plant species. Taking into account the existing link between ROS and secondary signaling messengers that lead to transcriptional regulation of secondary metabolism, in this perspective we put forward the argument that ROS induced in plants upon their interaction with NPs will likely interfere with plant secondary metabolism. As plant secondary metabolites play vital roles in plant performance, communication, and adaptation, a comprehensive understanding of plant secondary metabolism in response to NPs is an utmost priority.

ÖZAmaç: Bu çalışmanın amacı, yeşil kimya yöntemiyle çinko oksit nanopartiküllerini (ZnONPs) sentezlemek ve bu nanopartiküllerin anti-bakteriyel ve anti-kanser etkilerini incelemektir. Gereç ve Yöntemler: Çinko iyonları ve sulu enginar yaprağı (Cynara scolymus) ekstraktı kullanılarak ZnONPs yeşil kimya yöntemiyle sentezlendi. ZnONPs oluşumunun doğrulanması ve karakterizasyonu için morötesi-görünür bölge spektroskopisi (UV-Vis), Fourier dönüşümü kızılötesi spektroskopisi (FTIR), taramalı elektron mikroskobu (SEM), zetasizer ve Enerji dağınım X-ışını spektroskopisi (EDX) analizleri kullanıldı. ZnONPs'nin 4 farklı bakteri türü (E. coli, S. aureus, P. aeruginosa ve E. faecalis) üzerindeki antibakteriyel aktiviteleri, minimal inhibe edici konsantrasyon (MİK) ve kuyucuk difüzyon yöntemiyle ölçüldü. ZnONPs'nin HT-29 insan kolon kanseri hücreleri üzerindeki sitotoksik etkileri konsantrasyon ve zamana bağlı olarak olarak belirlendi. Bulgular: UV-Vis spektrumunda ZnO'ya spesifik olan 320-335 nm aralığında absorbans artışı gözlemlendi. FTIR spektrumunda 426 cm -1 ve 540 cm -1 'de ZnO'ya ait gerilme titreşimleri belirlendi. SEM analizinde partikül boyutu 276-309 nm ölçüldü. ZnONPs'nin zeta-sizer analizlerinde partikül büyüklüğü 137,8 nm ve partikül yükü -6,34 meV olarak bulundu. Antibakteriyel aktivite ölçümlerinde, sentezlenen nanopartiküllerin E. coli ve S. aureus'ta bakteriyel aktivite inhibisyonu sağladığı tespit edildi. ZnONPs HT-29 kolon kanseri hücreleri üzerinde 10 µg/mL'den daha yüksek konsantrasyonlarda sitotoksik etki gösterdi. Sonuç: ZnONPs'nin düşük maliyetle hazırlanabileceği ve klinik tedavilerde yeni ilaç formülasyonları için taşıyıcı sistem olarak kullanılma potansiyeline sahip olduğu bu çalışma ile gösterilmiştir. ABSTRACTAim: The aim of this study is to synthesize zinc oxide nanoparticles (ZnONPs) by green chemistry method and investigate anti-bacterial and anticancer effects of these nanoparticles. Material and Methods: ZnONPs were synthesized by the green chemistry method using zinc ions and aqueous artichoke leaf (Cynara scolymus) extract. Ultraviolet-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), zetasizer and energy dispersive X-ray spectroscopy (EDX) were used to confirm the formation and characterization of ZnONPs. Antibacterial activities of ZnONPs on four different bacteria species (E. coli, S. aureus, P. aeruginosa and E. faecalis) were measured by minimal inhibitory concentration (MIC) and agar well diffusion method. Cytotoxic effects of ZnONPs on HT-29 human colon cancer cells were determined as concentration and time dependent. Results: In the UV-Vis spectrum, absorbance increase was observed in 320-335 nm range which is specific to ZnO. In the FTIR spectrum, stretching vibrations of ZnO were determined in 426 cm -1 and 540 cm -1 . The particle size was 276-309 nm in SEM analysis. In the zeta-sizer measurements of ZnONPs, the particle size was 137.8 nm and the particle charge was -6.34 meV. In the antibacterial activity measu...
