“…Swarna) and described as phytostimulants in some active compounds (i.e., chlorophyll and carotenoids) without negative impacts on the plant [ 126 ]. On the other hand, the NP excess could produce phytotoxicity, oxidative stress damage, and genotoxic effects [ 125 , 127 ]. For example, growth inhibition, especially in the root zone, was evident in wheat ( Triticum aestivum L.) using copper nanoparticles (CuNPs) [ 128 ].…”

Numerous environmental and endogenous factors affect the level of genetic diversity in natural populations. Genetic variability is the cornerstone of evolution and adaptation of species. However, currently, more and more plant species and local varieties (landraces) are on the brink of extinction due to anthropopression and climate change. Their preservation is imperative for the sake of future breeding programs. Gene banks have been created worldwide to conserve different plant species of cultural and economic importance. Many of them apply cryopreservation, a conservation method in which ultra-low temperatures (−135 °C to −196 °C) are used for long-term storage of tissue samples, with little risk of variation occurrence. Cells can be successfully cryopreserved in liquid nitrogen (LN) when the adverse effect of ice crystal formation and growth is mitigated by the removal of water and the formation of the so-called biological glass (vitrification). This state can be achieved in several ways. The involvement of key cold-regulated genes and proteins in the acquisition of cold tolerance in plant tissues may additionally improve the survival of LN-stored explants. The present review explains the importance of cryostorage in agronomy and presents an overview of the recent works accomplished with this strategy. The most widely used cryopreservation techniques, classic and modern cryoprotective agents, and some protocols applied in crops are considered to understand which parameters provide the establishment of high quality and broadly applicable cryopreservation. Attention is also focused on the issues of genetic integrity and functional genomics in plant cryobiology.

“…Nevertheless, nanomaterials may also negatively influence plant metabolism, growth, and development. They are also used as mutagenic factors to induce genetic and phenotypic variation that is valuable in breeding [ 11 , 12 ]. The phytotoxicity of ENMs may be associated with the generation of reactive oxygen species (ROS), leading to lipid peroxidation and disturbances in the redox state of cells and, consequently, oxidative stress [ 6 , 13 ].…”

The interactions between nanoparticles and plant cells are still not sufficiently understood, and studies related to this subject are of scientific and practical importance. Silver nanoparticles (AgNPs) are one of the most commonly produced and used nanomaterials. This study aimed to investigate the influence of AgNPs applied at the concentrations of 0, 50, and 100 mg·L−1 during the process of in vitro germination as well as the biometric and biochemical parameters of developed seedlings in three vegetable species: Solanum lycopersicum L. ‘Poranek’, Raphanus sativus L. var. sativus ‘Ramona’, and Brassica oleracea var. sabellica ‘Nero di Toscana’. The application of AgNPs did not affect the germination efficiency; however, diverse results were reported for the growth and biochemical activity of the seedlings, depending on the species tested and the AgNPs concentration. Tomato seedlings treated with nanoparticles, particularly at 100 mg·L−1, had shorter shoots with lower fresh and dry weights and produced roots with lower fresh weight. Simultaneously, at the biochemical level, a decrease in the content of chlorophylls and carotenoids and an increase in the anthocyanins content and guaiacol peroxidase (GPOX) activity were reported. AgNPs-treated radish plants had shorter shoots of higher fresh and dry weight and longer roots with lower fresh weight. Treatment with 50 mg·L−1 and 100 mg·L−1 resulted in the highest and lowest accumulation of chlorophylls and carotenoids in the leaves, respectively; however, seedlings treated with 100 mg·L−1 produced less anthocyanins and polyphenols and exhibited lower GPOX activity. In kale, AgNPs-derived seedlings had a lower content of chlorophylls, carotenoids, and anthocyanins but higher GPOX activity of and were characterized by higher fresh and dry shoot weights and higher heterogeneous biometric parameters of the roots. The results of these experiments may be of great significance for broadening the scope of knowledge on the influence of AgNPs on plant cells and the micropropagation of the vegetable species. Future studies should be aimed at testing lower or even higher concentrations of AgNPs and other NPs and to evaluate the genetic stability of NPs-treated vegetable crops and their yielding efficiency.

“…This previous method did not apply for all cases of orchid rooting, which needs a special handling. The use of nanomaterials in enhancing the plant rooting and its growth under in vitro conditions has become recently a promising tool such as silver nanoparticles (Thangavelu et al 2018;Saha and Gupta 2018;Jadczak et al 2019;Ha et al 2020;Tymoszuk•and Kulus 2020), iron nanoparticles (Mozafari et al 2018 and Khan et MAYADA K. SELIEM et al al. 2020), zinc oxide nanoparticles (Nalci et al 2019;Abdel Wahab et al 2020; Mazaheri-Tirani and Dayani 2020), cobalt nanoparticles (Ha et al 2020), gold nanoparticle (Jadczak et al 2019), copper oxide nanoparticles (Javed et al 2017 andNalci et al 2019), copper nanoparticles (Ibrahim et al 2019), nickel oxide nanoparticles (Pinto et al 2019), and nano-Se (Sotoodehnia-Korani et al 2020).…”

O RCHID plants are considered one of the most valuable and largest flowering plant families, which have a premium position in the global market of cut-flowers. Rooting of orchids is still the main real problem that obstructs its propagation, as roots are hardly to develop.So, Orchid needs to improve its in vitro propagation by enhancing its rooting development. The plant tissue culture of orchids is the most promising field that has been commercially used for getting of virus-free and high-quality rooted plants and representing around 70% of transplants production. In this study the shoots of in vitro plantlets were separated and cultured on half MS medium supplemented with nano-Se (0,10, 20, 30, 40 and 50 mg l-1) or corresponding doses of bulk type selenite; sodium selenite (0, 0.5, 1, 2, 4, 6, 8 and 10 mg l-1) in separates treatments with or without 0.5 mg l-1 NAA (α-naphthalene acetic acid). The two different sources of selenium were selected at mentioned concentrations to improve orchid rooting and acclimatization. Supplementation of half MS medium with 50 mg l-1 nano-Se + 0.5 mg l-1 NAA recorded the highest significant values of rooting percentage and root length as well. Whereas, half MS medium fortified with 40 mg l-1 nano-Se + 0.5 mg l-1 NAA gave the optimum number of roots. On the other hand, this enhancing effect on rooting decreased after augmentation the culture medium with 10 mg l-1 selenite. It could be concluded that in vitro rooting of Phalaenopsis orchid was improved by supplementation of nano-Se up to 50 mg l-1 in presence of 0.5 mg l-1 NAA consequence, acclimatization process was enhanced.
