Genomic and proteomic insights into the heavy metal bioremediation by cyanobacteria

Plant Defense Strategies and Biomarkers against Heavy Metal-Induced Stress: A Comprehensive Review

“…For instance, changes in bark structure (soft or hard), leaf structures (thorns, suckers, and roots branching), spore formation, and seed production ensuring the survival of plant species, phytohormones level alteration, nutrient storage, photoperiodism, transpiration control via stomata, etc., are few of the morphological, physiological, and biochemical strategies employed by plants . The influence of plants on other living species is vital, and by monitoring them, thus it is easily possible to detect the impact of heavy metal (HM) stresses on the natural ecosystem . Several metabolites have been synthesized or secreted by plants as signaling molecules to initiate the defense response, and these signaling molecules can serve as a potential indicator to detect the presence of a particular stress in their ecosystem .…”

“…8 In this context, the use of plants' morphological, physiological, or metabolic responses (primary or secondary metabolites) as biomarkers tools (as indicatory or sensory means) to detect any changes around an environment has increased interest to global scientists and a hotspot of current research. 7 Generally, biomarkers are synthesized inside the biological systems and present physiological, morphological, or behavioral alterations, generating information about the environment's quality. This review sheds light on various heavy metals causing stress in plant systems, defense strategies employed by plants, the contribution of rhizosphere microbes, and potential compounds (metabolites) used as biomarkers to detect heavy metal stresses and try to draw a possible roadmap toward smart and sustainable agriculture.…”

Phenotypically Complex Living Materials Containing Engineered Cyanobacteria

“…Bioremediation is an area where ELMs containing genetically modified organisms are likely to provide substantial benefit 33,34 . Previous work has demonstrated that cyanobacteria are capable of producing both native and recombinant enzymes with relevance to bioremediation [35][36][37] .…”

“…Bioremediation is an area where ELMs containing genetically modified organisms are likely to provide substantial benefit 33,34 . Previous work has demonstrated that cyanobacteria are capable of producing both native and recombinant enzymes with relevance to bioremediation 35–37 . In this work, we aimed to develop stimuli-responsive ELMs that decontaminate chemical pollutants by regulating the production of an enzyme capable of degradation.…”

Unveiling glutamic acid-functionalized LDHs: understanding the Cr(vi) removal mechanism from microscopic and macroscopic view points

“…18 Amino acids are multifunctional molecules that play an important role in chelating heavy metal ions and preparing metal oxides/hydroxides. [19][20][21] According to reports, it has been shown that organic intercalated LDHs can effectively remove various heavy metal ions (Co 2+ , Pb 2+ , Cd 2+ , Cu 2+ , and Ni 2+ ), 22,23 ,), 24 and organic dyes (Congo red and methylene blue), 25,26 among others. Recently, our research group has provided a detailed understanding of the mechanism behind the intercalation of organic compounds into LDHs at the microscale, and we have conducted a comprehensive atomic-scale analysis of how the intercalated molecules facilitate the removal of heavy metal ions.…”
