“…This amino acid is accumulated under HM stress as a compatible solute and antioxidant (Lefèvre et al 2014;Fourati et al 2019). Results obtained in St Ni line are consistent with our previous observations of Ni-induced physiological disorders related to osmotic stress in D. jasminea (Wiszniewska et al 2018). Stable content of proline in Lt Ni line may be an indicator of effective control of osmotic homeostasis and may reflect reduced Ni toxicity during prolonged exposure (Zou et al 2013;Islam et al 2014).…”

The study aimed at distinguishing antioxidant responses conditioning acclimation status to metallic stress in a shoot culture of a woody plant Daphne jasminea. Growth, organogenesis, metal accumulation, oxidative stress level and antioxidant responses were compared in the long-term treated shoots (Lt lines) and short-term treated (St lines) with Cd, Ni and Pb in relation to control shoots. Growth rate and organogenic potential were higher in the long-term treated Lt Cd and Lt Pb lines than in respective short-term treated St lines. Lt Ni line proliferated less effectively than St Ni line, whereas biomass accretion was similar in both Ni lines. All heavy metal (HM)-exposed shoots suffered from oxidative stress, however, it was more severe in St than in Lt lines. In the long-term treated lines three major factors were associated with the acclimation status: activity of peroxidase (POD) and accumulation of anthocyanins and carotenoids. POD activity was 4-1.5-times higher in Lt lines than in the control one. Anthocyanin content nearly tripled, while carotenoid content doubled in Lt lines. Other elements of antioxidant system, CAT and SOD, glutathione, ascorbic acid and proline, complemented the action of the "major players" in long-term treated Lt lines depending on heavy metal type. Short-term treated lines responded by accumulation of proteins and a decline in catalase activity. The study demonstrated that long-term heavy metal treatment can be considered acclimation strategy, during which substantial modulation of the antioxidant system occurs. Due to orchestrated action of cytosolic POD, vacuolar anthocyanins and membrane-bound carotenoids HM toxicity could be counteracted in various cellular compartments. Key message Acclimation to heavy metal exposure in D. jasminea shoot cultures involves modulation of antioxidant activity and is conditioned by an orchestrated action of cellular peroxidases, vacuolar anthocyanins and membrane-bound carotenoids.

“…JA concentration in the roots of Arabidopsis is also elevated following the treatment of Cd for 6 h, the content is higher than control at 3 days but shows no significant difference after 7 days (Lei et al, 2020b). Increased levels of JAs are observed in Cu-or Cd-treated runner bean (Phaseolus coccineus; Maksymiec et al, 2005), Cd-treated pea (Pisum sativum; Rodríguez-Serrano et al, 2006), Ni-exposed woody shrub Daphne jasmine (Wiszniewska et al, 2018), and Cu-affected rice leaves (Rakwal et al, 1996). Moreover, the increased production of JA in hyperaccumulator Noccaea (Thlaspi) praecox by Cd is dependent on mechanically puncturing or fungal infection (Llugany et al, 2013), indicating the positive roles of Cd-induced JA in metal hyperaccumulators under abiotic and biotic stresses.…”

An increase in environmental pollution resulting from toxic heavy metals and metalloids [e.g., cadmium (Cd), arsenic (As), and lead (Pb)] causes serious health risks to humans and animals. Mitigation strategies need to be developed to reduce the accumulation of the toxic elements in plant-derived foods. Natural and genetically-engineered plants with hyper-tolerant and hyper-accumulating capacity of toxic minerals are valuable for phytoremediation. However, the molecular mechanisms of detoxification and accumulation in plants have only been demonstrated in very few plant species such as Arabidopsis and rice. Here, we review the physiological and molecular aspects of jasmonic acid and the jasmonate derivatives (JAs) in response to toxic heavy metals and metalloids. Jasmonates have been identified in, limiting the accumulation and enhancing the tolerance to the toxic elements, by coordinating the ion transport system, the activity of antioxidant enzymes, and the chelating capacity in plants. We also propose the potential involvement of Ca2+ signaling in the stress-induced production of jasmonates. Comparative transcriptomics analyses using the public datasets reveal the key gene families involved in the JA-responsive routes. Furthermore, we show that JAs may function as a fundamental phytohormone that protects plants from heavy metals and metalloids as demonstrated by the evolutionary conservation and diversity of these gene families in a large number of species of the major green plant lineages. Using ATP-Binding Cassette G (ABCG) transporter subfamily of six representative green plant species, we propose that JA transporters in Subgroup 4 of ABCGs may also have roles in heavy metal detoxification. Our paper may provide guidance toward the selection and development of suitable plant and crop species that are tolerant to toxic heavy metals and metalloids.

“…In turn, M HM-treated shoots were characterized by stimulated production of jasmonic acid (JA), whereas ABA content remained constant in both treatments. Although these phytohormones share the common target of limiting water losses by stomatal closure 58 , JA is also known to ameliorate oxidative damage through the activation of antioxidant machinery 22 , 59 , 60 . In the case of our study, JA seemed to take part in the ROS removal pathways rather than in stomatal closure since this last process often refers to the restricted conversion of 12-OPDA to JA, which then promotes the stomatal movement individually or jointly to ABA 21 .…”

In recent years, great progress has been achieved toward explaining the roles of exogenously applied phytohormones in the mitigation of metal toxicity 19 , 22 . Despite many efforts held to elucidate the functions of both individual phytohormones and their interactions under HM treatment, there is limited information about their profiling and significance in metallophytes as tolerant representatives that are the best adapted by microevolutionary changes to grow in heavily contaminated areas 23 , 24 .…”

The present study investigated the response of non-metallicolous (NM) and metallicolous (M) Alyssum montanum shoots cultured in vitro on a medium supplemented simultaneously with heavy metals (HMs) to identify mechanisms involved in alleviating metal-induced damage. Plant status in respect to photosynthetic apparatus efficiency was determined and linked with changes in biochemical composition of shoots, namely phenolic acids’ and stress-related phytohormones. Results showed the considerable inter-ecotype differences in (1) the photosynthetic pigments’ amount, (2) the functioning of membrane electron transporters as well as (3) the linear and alternative electron transport pathways, whose lower values were reported in NM than in M HM-treated culture. Photosynthetic apparatus protection in M specimens was assured by the activation of cinnamic acid synthesis (by phenylalanine ammonia lyase) and its further transformations to benzoic acid derivatives with high ability to counteract oxidative stress, that was accompanied by the overexpression of jasmonic acid stimulating antioxidant machinery. In turn, detrimental HM effects on NM shoots could result from the diminution of most phenolics’ accumulation, and only the content of coumarate (produced by bifunctional phenylalanine/tyrosine ammonia lyase) and rosmarinic acid increased. All these together with an enhanced concentration of abscisic acid might suggest that NM strategy to cope with HMs is based mostly on a restriction of metal movement with transpiration flow and their limited distribution in leaves. Summarizing, our findings for the first time point out the physiological and metabolic adaptation of pseudometallophyte A. montanum to adverse conditions.
