“…A summary of the overall benefits of the PGRs most-commonly applied to mitigate the effects of abiotic stresses in plants is provided in Table 2. Other PGRs (e.g., gibberellins, cytokinins, and auxins) are often applied to promote growth or modulate specific processes of plant development, but their use to induce stress responses has recently been raised, especially as priming agents (Bryksová et al, 2020;Dolui et al, 2022;Zhu et al, 2021). The application of PGRs can be hindered due to the chemical characteristics of the molecules, such as the rapid degradation of these compounds when exposed to the light and temperatures found in the field, resulting in some loss of the their biological activity (Pascoli et al, 2018;Seabra et al, 2015).…”

“…A study on Cd hyperaccumulator Silene sendtneri revealed that antioxidant activity increased only in some of the applied priming combinations, and, thus, it was not a versatile response [19]. Moreover, priming with synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) seemed to stimulate oxidase activity and peroxidation reactions in hyperaccumulating fern Salvinia natans [20]. Studies identifying specific reactions to priming in related tolerant and susceptible genotypes are also lacking.…”

This study investigated the impact of several priming agents on metal-tolerant and sensitive Silene vulgaris ecotypes exposed to environmentally relevant cadmium dose. We analyzed how priming-induced changes in the level of lipid, protein, and DNA oxidation contribute to calamine (Cal) and non-calamine (N-Cal) ecotype response to Cd toxicity, and whether the oxidative modifications interrelate with Cd tolerance. In non-primed ecotypes, the levels of DNA and protein oxidation were similar whereas Cal Cd tolerance was manifested in reduced lipid peroxidation. In both ecotypes protective action of salicylic acid (SA) and nitric oxide (NO) priming was observed. SA stimulated growth and reduced lipid and DNA oxidation at most, while NO protected DNA from fragmentation. Priming with hydrogen peroxide reduced biomass and induced DNA oxidation. In N-Cal, priming diminished Cd accumulation and oxidative activity, whereas in Cal, it merely affected Cd uptake and induced protein carbonylation. The study showed that priming did not stimulate extra stress resistance in the tolerant ecotype but induced metabolic remodeling. In turn, the lack of adaptive tolerance made the sensitive ecotype more responsive to the benefits of the primed state. These findings could facilitate priming exploitation with a view of enhancing metallophyte and non-metallophyte suitability for phytoremediation and land revegetation.

“…tion cartridges are employed for the extraction of phytohormones from complex plant matrices (SPE) (Dobrev et al, 2012;Kosakivska et al, 2020). Despite their distinctive morphology, significant adaptation potential, wide distribution and effective use in phytoremediation, the phytohormonal complex of species in the Salviniaceae family remains inadequately researched.…”

Water ferns of the Salviniaceae family are successfully used for bioremediation and bioindication of contaminated waters. Due to intensive propagation they are able to produce a great volume of biomass enriched with natural plant growth regulators. Simultaneously, water ferns have become an impediment to the use of water resources through the fast spread. Their growth and development is under control of phytohormones, which are main chemical messengers regulating the responses to environmental changes. Today hormonal system of water ferns of the Salviniaceae family remains understudied. In this review, we analyzed and summarized the literature data and the results of our own research about the role of auxins, cytokinins, gibberellic, abscisic, salicylic and jasmonic acids in regulation of growth and development of water ferns from Salvinia and Azolla genera emphasizing the specific hallmarks of these phytohormones in ferns. We have submitted brief information about methodological approaches for endogenous phytohormones determination in water ferns of the Salviniaceae family. The effects of exogenous regulators on growth, development and tolerance of water macrophytes from Salvinia and Azolla genera were discussed, as well as the possibility of using water ferns to create ecological biofertilizers.
