“…They found up to 61% and 70% polymorphism rates using IRAP and iPBS, respectively. In another study, Yigider et al [21] also revealed Sukkula polymorphism under manganese treatment in Zea mays. In addition to the plant genome, Alu, SVA and HerV elements have been reported as active in the human genome, although active elements are limited [22,23].…”

Retrotransposons, a subclass of mobile genetic elements, have been discovered in many organisms. In this study, we identified a plant-specific retrotransposon (Sukkula) in the human genome (24 different DNA samples) by using retrotransposon-based molecular marker technique: interretrotransposon amplified polymorphism. There were five different groups related to the ages of the subjects. The polymorphism ratios were 8%-100% among all samples, 10%-91% among females (12 subjects) and 13%-100% among males (12 subjects). Moreover, we also observed 8%-91% polymorphism ratios when comparing males to females. To the best of our knowledge, this is one of the first reports on plant-specific retrotransposons in the human genome. The obtained findings are expected to contribute to broadening the knowledge about plant retrotransposons in the human genome and their role in human genome evolution.

“…Moreover, several studies highlight various physiochemical and biological properties of HS to explain their significance in soil fertility ( Hirel et al, 2007 ; Brown et al, 2014 ). However, considerable gaps still exist in our understanding of how HS induce signaling in plants that allows them to cope with heavy metal genotoxicity ( Yigider et al, 2016 ), epigenetic modifications ( Erturk et al, 2015 ), and building rhizospheres and microbial interactions ( Gao et al, 2015 ). Moreover, the unique molecular structure of HS and their relative response to antioxidant, drought, and salt stresses has been reported to explain the biological effect of HS on plants ( Canellas and Olivares, 2014 ); one such mechanism involves binding of HS with inorganic trace mineral elements that can then be utilized by various crop plants to trigger potential molecular processes.…”

“…Therefore, plants have also evolved processes that can suppress TE activity ( Pecinka et al, 2010 ). Yigider et al (2016) reported that Mn exhibits a dynamic role in inducing epigenetic changes in Zea mays ; however, its effect is countered by HA treatments at different doses. In fact, the protective action of HS is associated with their antioxidant and enzyme-regulatory actions, which are reflected in the reduced expression of TEs ( Picault et al, 2009 ; Yigider et al, 2016 ).…”

HS augment the tolerance of plants to heavy metal toxicity ( Table 1 ) by coordinating the actions of non-enzymatic antioxidants and ROS-detoxification enzymes.…”

Humic Substances: Determining Potential Molecular Regulatory Processes in Plants

Humic substances (HSs) have considerable effects on soil fertility and crop productivity owing to their unique physiochemical and biochemical properties, and play a vital role in establishing biotic and abiotic interactions within the plant rhizosphere. A comprehensive understanding of the mode of action and tissue distribution of HS is, however, required, as this knowledge could be useful for devising advanced rhizospheric management practices. These substances trigger various molecular processes in plant cells, and can strengthen the plant’s tolerance to various kinds of abiotic stresses. HS manifest their effects in cells through genetic, post-transcriptional, and post-translational modifications of signaling entities that trigger different molecular, biochemical, and physiological processes. Understanding of such fundamental mechanisms will provide a better perspective for defining the cues and signaling crosstalk of HS that mediate various metabolic and hormonal networks operating in plant systems. Various regulatory activities and distribution strategies of HS have been discussed in this review.

“…Additionally manganese chloride has a mutagenicity effect against TA1537 strain of S. typhimurium (Lima et al 2007). There are many studies explaining that manganese causes DNA damage in plants (Enan, 2006;Zhou et al, 2013;Yigider et al, 2016). In accordance with the WHO (World Health Organization) data, All Mn forms have mutagenic impact in vivo and in vitro and further research should be performed to clarify the mutagenicity potential of Mn.…”

Heavy metal accumulation and its possible effects are prominent problem for not only human health but also for the environment and plant systems due to that heavy metals are non-biodegradable. In this research, it was aimed to examine the impacts of heavy metals on toxicity and genotoxicity in maize. Seeds of corn were subjected to various concentrations of MnSO4 and CuSO4 for determining their effects on DNA methylation, DNA damage levels, protein and phytohormone alterations. The results revealed that an increase in copper and manganese concentrations causes decrease in soluble protein levels, genomic template stability (GTS) and mitotic index but causes an increase in RAPD profile alterations and DNA hypermethylation. Additionally, HPLC analyses show that CuSO4 and MnSO4 contamination reduces growth-promoting hormones, like gibberellic acid (GA), zeatin (ZA) and indole acetic acid (IAA), and increases the abscisic acid (ABA). This study obviously indicated that CuSO4 and MnSO4 have epigenetic and genotoxic effects. A decrease in the phytohormone level (ZA, GA, and IAA) and an increase in the ABA level under CuSO4 and MnSO4 are thought to be a part of the defense system of maize to struggle with stress.
