“…The rhizospheric soil was collected from the three host plant species Bidens pilosa L., Tagetes minuta L. and Sorghum halepense (L.) Pers. Although not all these species were found at all sites, these were the most abundant in the study area and have been previously studied for Pb accumulation in both field and experimental conditions (Cid et al, 2016;Graziani et al, 2016;Salazar and Pignata, 2014;Salazar et al, 2016a;Salazar et al, 2016b;Sosa et al, 2016).…”

“…Whereas total protein, proline as well as chlorophyll, and carotenoid contents were increased up to 75 μM and after that decreased on further increase in CuSO 4 . Similarly, increased chlorophyll and carotenoid contents were observed in T. minuta in the presence of lead ( del Carman Sosa et al., 2016 ) and an enhanced level of proline content in Cajanus cajan due to Cu stress ( Hayat et al., 2021 ).…”

“…The shoot fresh and dry weights were reduced by increasing the concentration of CuSO 4 in the medium. However, enhanced shoot biomass accumulation is reported in Tagetes minuta in the presence of lead ( del Carman Sosa et al., 2016 ). Whereas total protein, proline as well as chlorophyll, and carotenoid contents were increased up to 75 μM and after that decreased on further increase in CuSO 4 .…”

In the present study, we addressed the imperative for potent anticancer agents through Wedelia chinensis, a medicinal plant abundant in the robust antihepatotoxic and antitumor compound wedelolactone. Hindrances in conventional propagation methods due to cross-pollination and habitat degradation prompted us to pioneer in vitro rapid multiplication using plant tissue culture. Optimal outcomes were attained employing Murashige and Skoog (MS) medium supplemented with Indole-3-butyric acid (IBA) (0.5 mg/L) and Kinetin (KN) (5.0 mg/L), yielding 97.67% shoot regeneration and 81.67% rooting from nodal explants. Transplanted plantlets exhibited a 92% survival rate. We established a wedelolactone extraction protocol using toluene:ethyl acetate:formic acid (5:4:1) for High-performance thin-layer chromatography (HPTLC) analysis, trailblazing wedelolactone quantification and 2C DNA analysis in W. chinensis via flow cytometry. Experiments under heavy metal stress with CuSO4 unveiled physiological responses, with peak wedelolactone content [193.90 μg/g dry weight (dw)] in vitro at 75 μM CuSO4, surpassing in vivo levels (89.95 μg/g dw) by 116%. By pioneering successful in vitro rapid multiplication and enhanced wedelolactone content, we bridge a critical gap in the conservation and production of this medicinal plant. Our findings not only offer a sustainable means of propagation but also present a viable strategy for elevating the yield of potent bioactive molecules like wedelolactone, holding immense promise for the development of novel therapeutic interventions and addressing the pressing healthcare challenges of our time.

However, Carman Sosa et al (2016) revealed that Tagetes minuta plants growing in areas polluted with lead, while lead was not found in essential oil and some ingredients were generated more than control group. Novo et al (2013) reported concerning the capacity of Salvia verbenaca to bear trace metals and actively replied to the following oxidative stress.…”

In this study, ecotoxicological and ecophysiological effects of some different heavy metal compounds (CdCl2, PbCl2, and CuCl2) on Salvia candidissima subsp. occidentalis Hedge (Lamiaceae) were examined. Seeds of this plant were exposed to three different concentrations of CdCl2 (2, 6, 10 ppm), PbCl2 (50, 100, 500 ppm), and CuCl2 (20, 60, 150 ppm). The results indicated that increasing CdCl2 and PbCl2 concentrations had no specific inhibitory impacts on seed germination rates, growth performance, biomass, and seedling vigor index, but increasing concentrations of CuCl2 had significant inhibitory effects on these parameters. The metal tolerance index of all applications showed that all heavy metal treatments reduce this value.
