“…Nonetheless, in leaves no increase was observed in lipid peroxidation despite the increase in O 2 − and H 2 O 2 production. The increase in the production of ROS induced by Sb in D. viscosa is similar to that described for other plants in response to toxicity from both Sb and other heavy metals [ 17 , 35 , 38 , 55 , 57 , 87 , 106 , 107 , 108 ]. Nonetheless, the increase in O 2 ●− production was much less than that observed previously by our group for sunflower and tomato [ 17 , 38 ], reflecting D. viscosa ’s greater tolerance to Sb stress.…”

“…On the contrary, numerous studies have observed an increase in these activities in response to Sb [ 17 , 32 , 38 , 91 , 111 ]. Nonetheless, in Dittrichia , a plant tolerant to Sb [ 56 , 57 , 94 ], the SOD and APX activities decrease in roots. The different responses of these antioxidant enzymes depending on the organ was also observed by Rodríguez-Ruíz et al [ 95 ] for pea plants subjected to As stress, for which the expression of SOD decreased strongly in roots but not in leaves, while APX activity increased in roots and decreased in leaves.…”

“…The objective of this investigation was to study the physiological response to Sb toxicity, shown by Dittrichia viscosa , a plant that accumulates this metalloid [ 56 , 57 ] and that is considered to be a good candidate for use in Sb, Cd, and As phyto-extraction processes [ 58 , 59 ]. In particular, we determined the effect that Sb toxicity has on biomass growth and production, mineral element absorption, photosynthetic pigment content, ROS, RNS, and H 2 S levels, and antioxidant systems.…”

Dittrichia viscosa plants were grown hydroponically with different concentrations of Sb. There was preferential accumulation of Sb in roots. Fe and Cu decreased, while Mn decreased in roots but not in leaves. Chlorophyll content declined, but the carotenoid content increased, and photosynthetic efficiency was unaltered. O2●− generation increased slightly, while lipid peroxidation increased only in roots. H2O2, NO, ONOO−, S-nitrosothiols, and H2S showed significant increases, and the enzymatic antioxidant system was altered. In roots, superoxide dismutase (SOD) and monodehydroascorbate reductase (MDAR) activities declined, dehydroscorbate reductase (DHAR) rose, and ascorbate peroxidase (APX), peroxidase (POX), and glutathione reductase (GR) were unaffected. In leaves, SOD and POX increased, MDAR decreased, and APX was unaltered, while GR increased. S-nitrosoglutathione reductase (GSNOR) and l-cysteine desulfhydrilase (l-DES) increased in activity, while glutathione S-transferase (GST) decreased in leaves but was enhanced in roots. Components of the AsA/GSH cycle decreased. The great capacity of Dittrichia roots to accumulate Sb is the reason for the differing behaviour observed in the enzymatic antioxidant systems of the two organs. Sb appears to act by binding to thiol groups, which can alter free GSH content and SOD and GST activities. The coniferyl alcohol peroxidase activity increased, possibly to lignify the roots’ cell walls. Sb altered the ROS balance, especially with respect to H2O2. This led to an increase in NO and H2S acting on the antioxidant system to limit that Sb-induced redox imbalance. The interaction NO, H2S and H2O2 appears key to the response to stress induced by Sb. The interaction between ROS, NO, and H2S appears to be involved in the response to Sb.

“…Dittrichia can colonize poor soils and also those that are degraded due to anthropic activities, such as mining, with high concentrations of heavy metals and metalloids [ 58 ]. Dittrichia are capable of absorbing and accumulating large amounts of Cd, Cu, Fe, Ni, Pb, Zn, As, and Sb [ 11 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ]. The participation of the components of the AsA–GSH cycle, as well as NO and H 2 S, in the Sb accumulation process has recently been reported [ 11 , 63 ].…”

Effect of Thallium(I) on Growth, Nutrient Absorption, Photosynthetic Pigments, and Antioxidant Response of Dittrichia Plants

Dittrichia plants were exposed to thallium (Tl) stress (10, 50, and 100 µM) for 7 days. The Tl toxicity altered the absorption and accumulation of other nutrients. In both the roots and the leaves, there was a decline in K, Mg, and Fe content, but an increase in Ca, Mn, and Zn. Chlorophylls decreased, as did the photosynthetic efficiency, while carotenoids increased. Oxidative stress in the roots was reflected in increased lipid peroxidation. There was more production of superoxide (O2.−), hydrogen peroxide (H2O2), and nitric oxide (NO) in the roots than in the leaves, with increases in both organs in response to Tl toxicity, except for O2.− production in the roots, which fluctuated. There was increased hydrogen sulfide (H2S) production, especially in the leaves. Superoxide dismutase (SOD), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), monodehydroascorbate reductase (MDHAR), and glutathione reductase (GR) showed increased activities, except for APX and MDHAR in the roots and GR in the leaves. The components of the ascorbate–glutathione cycle were affected. Thus, ascorbate (AsA) increased, while dehydroascorbate (DHA), reduced glutathione (GSH), and oxidized glutathione (GSSG) decreased, except for in the roots at 100 µM Tl, which showed increased GSH. These Tl toxicity-induced alterations modify the AsA/DHA and GSH/GSSG redox status. The NO and H2S interaction may act by activating the antioxidant system. The effects of Tl could be related to its strong affinity for binding with -SH groups, thus altering the functionality of proteins and the cellular redox state.

“…However, T. articulate is better suited for phytomanagement of metal enriched soils due its higher biomass and lower metal translocation into aerial tree compartments in relation to P. halepensis. Garrido et al (2020) investigated the accumulation of Sb in leaves of Dittrichia viscosa growing in soils of the abandoned Sb mine ''San Antonio'', Alburquerque, Badajoz, Spain and the effect on the oxidant/antioxidant systems and the photosynthetic efficiency. The authors found the high Sb accumulation capacity in the leaves and an increase in the carotenoids/chlorophyll ratio without affectation of the photosynthetic efficiency.…”

Background This collection of papers submitted to this Special Issue is mainly an outgrowth from the Symposium C3.5.2. 21WCSS ''Native metallophytes from mine spoils as a potential source for phytoremediation'' held in Rio, August 2018. The ensemble of papers of this Special Issue aims to offer the most recent findings, and state-of-the-art development in phytoremediation technologies using native metallophytes species. It implies a thorough identification of metallophytes colonizing contaminated sites and research in situ and laboratory experiments on the physiological behaviour of these species to cope with high concentrations of metals (loids) in mining, industrial and urban soils. The knowledge of plant physiology, anatomy, biochemistry, ecology, proteomics and genomics will also be essential for understanding the fundaments of plant tolerance.
