“…Other studies [ 144 , 145 , 146 ] have shown that polyamines act as a key signal in organogenesis and shoot regeneration. In addition, nanoparticles (e.g., TiO 2 , Ag, Zn, ZnO, graphite, graphene, carbon nanotubes, quantum dots, and polymer dendrimers) have been successfully used in different In Vitro processes from the first step, through decontamination, to callogenesis, organogenesis, somatic embryogenesis, shoot regeneration, the study and production of secondary metabolites, and somaclonal variation [ 147 , 148 , 149 , 150 ]. For instance, Sarmast et al [ 151 ] showed that adding 60 mg/l Ag nanoparticles to MS medium containing 0.1 mg/l IAA and 2.5 mg/l BAP increased shoot regeneration frequency, shoot number, and length of Tecomella undulata .…”

The recent legalization of Cannabis sativa L. in many regions has revealed a need for effective propagation and biotechnologies for the species. Micropropagation affords researchers and producers methods to rapidly propagate insect-/disease-/virus-free clonal plants and store germplasm and forms the basis for other biotechnologies. Despite this need, research in the area is limited due to the long history of prohibitions and restrictions. Existing literature has multiple limitations: many publications use hemp as a proxy for drug-type Cannabis when it is well established that there is significant genotype specificity; studies using drug-type cultivars are predominantly optimized using a single cultivar; most protocols have not been replicated by independent groups, and some attempts demonstrate a lack of reproducibility across genotypes. Due to culture decline and other problems, the multiplication phase of micropropagation (Stage 2) has not been fully developed in many reports. This review will provide a brief background on the history and botany of Cannabis as well as a comprehensive and critical summary of Cannabis tissue culture. Special attention will be paid to current challenges faced by researchers, the limitations of existing Cannabis micropropagation studies, and recent developments and future directions of Cannabis tissue culture technologies.

“…Over the past few decades, ENMs have been used in industrial sectors and in daily life, in biotechnology, and in agriculture, which has led to their inevitable release into the environment and ecosystems and has created possible hazards for all living organisms, including plants. Understanding the influence of ENMs on plants is crucial, not only from the scientific point of view but also for the assessment of environmental risks on food safety and human health [ 1 , 2 , 3 , 4 , 5 ].…”

“…The good electrical conductivity and photochemical properties result in their implementation in electronic devices and wastewater treatment. Silver nanoparticles are also used in agriculture as plant growth stimulators, fungicides, or agents to enhance fruit ripening [ 4 , 5 ]. AgNPs are assumed to modify the structural components of cellular membranes, macromolecules, influence cell division and defense systems, and interfere in the physiological and biochemical processes of plants by altering gene expression [ 7 ].…”

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.

“… 35 Application of silver nanoparticles (AgNPs) in plant tissue culture had proved their positive role in callus induction, somatic embryogenesis, organogenesis, somaclonal variation, genetic transformation, and secondary metabolites production. 41 Supplementing Ag in modified culture media in the form of AgNO 3 and Ag 2 S 2 O 3 can improve regeneration of plants. The improvement in regeneration of shoots is more potent when AgNPs are supplemented in the media than its other ionic counterparts, i.e., AgNO 3 and Ag 2 S 2 O 3 .…”
