Background: Heavy metal toxicity in contaminated settings generated a variety of physiological stress responses, resulting in damage to biological components like membranes, proteins, and DNA. Nicotiana glauca is an Egyptian invasive plant with a contradictory trend, making it difficult to assess its environmental contamination stance
The goal of this study was to explore phytomass, heavy metal concentrations, molecular expression (RAPD), and heavy metal (HM) partitioning and allocation plasticity in N. glauca using regular statistical as well as Meta-analyses (Box and Whisker plot and Pearson correlation coefficient).
The maximum heavy metal partitioning ranged from 1.15 for Mn to 9.03 for Cd, with both BCF and TF being more than one. Except for Ni in the root and Cd in the shoot, all metals showed a 100 percent significant connection in all sites. In comparison to BCF, TF, and PEC, copper had a wider interquartile range. Although all sites had a high GTS percent, site 10 had the most total number of bands and the greatest GTS percent, as well as the lowest proportion of polymorphism. Site 1, on the other hand, has the largest percentage of polymorphism and distinct bands.
Conclusion: A meta-analysis demonstrated that Nicotiana glauca is a hyperaccumulator species capable of accumulating large levels of heavy metals and adapting to polluted settings without undergoing significant genetic alterations.
