and Pb by inductively coupled plasma-optical emission spectrometry (ICP OES) was performed on dry matter and decoctions of the medicinal plants Cordia salicifolia, Chiococca alba (L.) Hitchc., and Echites peltata used as an appetite suppressant and diuretic in Brazil. e accuracy of the measurements was analyzed by the spike recovery test. Results showed that the concentration of these seven metals (Cd, Co, Cr, Cu, Fe, Na, and Zn) in dry plant samples is below the oral concentration of elemental impurities established by the United States Pharmacopoeia Convention (USP). However, there are no concentration limits for Fe, Na, and Zn established by the USP in drug substances and excipients. Levels higher than the recommended value by the USP were observed for Pb and the lowest for Cd, Co, Cr, and Cu, both in dried plant samples and their decoctions. In the decoctions prepared from these plants were found elements such as Cd, Co, Cr, Cu, Fe, Na, Zn, and Pb. In the decoction prepared from 40 g C. salicifolia leaves and 40 g C. alba wood, the content of Cd is above the oral daily exposure value set by the USP. Hazard index (HI) for decoctions prepared from these plants exceeded the threshold (1). Given the uncertainties associated with the estimates of toxicity values and exposure factors, futures researches should address the possible toxicity in humans. Uncontrolled selling and long-term ingestion of medicinal plants can cause toxicity and interfere with the effect of drugs. Limited knowledge on the interaction potential of medicinal plants poses a challenge and public health problem in Brazil and other countries.

“…The Cd triggers a set of complex changes in root morphology which later on through the apoplastic pathway disrupt the complete metabolism of the plant (Chen et al 2011). This decline in total growth might be due to lowered water potential and nutrient imbalance caused by heavy metal stress (Jibril et al 2017).…”

In silico identification and expression analysis of Metal-nicotianamine transporter (YSL3) and Oligopeptide transporter 3 (OPT3) under Cd stress in Brassica oleracea var. acephala

Background: Metal-nicotianamine transporter (YSL) family protein belongs to the oligopeptide heavy metal transporter group, as characterized in Arabidopsis thaliana. Oligopeptide transporters (OPTs) are a group of membrane-localized proteins, involved in different transport mechanisms, contributing to nitrogen mobilization, glutathione transport and long-distance metal distribution. Metal-nicotianamine transporter gene 3 (YSL3) incorporates the oligopeptide transporter domain, found to transfer several heavy metals in diverse plant species, and among them cadmium transport in Brassica oleracea. Objective: To evaluate and confirm the expression of Metal-nicotianamine transporter (YSL3) under cadmium stress. Studied species: Brassica oleracea var. acephala Study site and dates: Brassica oleracea var. acephala samples were collected from Blagaj region, Bosnia and Herzegovina. Methods: Through a simple bioinformatic approach the interactome partner of Metal-nicotianamine transporter (YSL3) was discovered and annotated. Oligopeptide transporter 3 (OPT3) and Metal-nicotianamine transporter (YSL3) genes were checked for expression levels under cadmium stress. Results: We have identified a strong interacting partner of YSL3, later confirmed as Oligopeptide transporter 3 (OPT3) protein in Brassica oleracea. The in vitro expression analysis by using a qRT-PCR revealed a significant upregulation of YSL3 and OPT3, during Cd stress. Conclusions: These findings indicate that the represented in-silico approach, followed by in vitro gene expression study, successfully confirmed YSL3 and identified OPT3 as a new gene, in correlation to cadmium stress.

“…Proline, which is a component of the non-specific defense systems against heavy metal toxicity acts as a chelator as well as a protein stabilizer in plants (Sharma & Dubey, 2005). The contents of proline increased in lettuce plants under Cd 2+ stress (Jibril et al, 2017) and in wheat plants exposed to Pb stress (Lamhamdi et al, 2013).…”

This study was conducted to determine the root tolerance and biochemical responses of four Chinese Lactuca sativa L. genotypes (Lüsu, Lümeng, Yidali and Anyan) to cadmium (Cd2+) stress. Twenty-eight days old seedlings were exposed to Hoagland’s nutrient solution supplied with or without 100 µM CdCl2 and monitored for seven days in a climate controlled room. The 100 µM CdCl2 significantly (P < 0.001) decreased all the root morphological indexes of the four genotypes. However, Yidali, which possessed the smallest root system, exhibited greater root tolerance to Cd2+ by having the highest tolerance indexes for root volume (46%), surface area (61%), projected area (74%) and numbers of root forks (63%) and root tips (58%). Moreover, Cd2+ stress also caused increases in H2O2 contents in the roots but the increase was least in Yidali which showed greater root tolerance to Cd2+stress. The effect of Cd2+ stress on the contents of hormones in the roots depended on the genotypes. Under Cd2+ stress, abscisic acid correlated positively with indole-3-acetic acid (r = 0.669*), gibberellic acid (r = 0.630*) and cytokinin (r = 0.785**). The antioxidant enzyme activities and proline responses of the four genotypes to Cd2+ stress were similar. The SOD activity was decreased whiles the CAT and POD activities, as well as the contents of proline increased in all the genotypes under the stress condition. These results suggest that lettuce genotypes with smaller root systems could be more tolerant to Cd2+ stress compared to those with larger root systems.
