“…Heavy metals emitted from various sources are accumulated on the soil surface [18,21,22]. Human activities are the main cause of heavy metal pollution [17,23,24]. Every year, millions of tons of heavy metals are released into the air, which destroy environmental ecology and ecosystem and negatively affect human health [25][26][27][28][29][30].…”

Vehicular emissions cause heavy metal pollution and exert negative impacts on environment and roadside vegetation. Wild plants growing along roadsides are capable of absorbing considerable amounts of heavy metals; thus, could be helpful in reducing heavy metal pollution. Therefore, current study inferred heavy metal absorbance capacity of some wild plant species growing along roadside. Four different wild plant species, i.e., Acacia nilotica L., Calotropis procera L., Ricinus communis L., and Ziziphus mauritiana L. were selected for the study. Leaf samples of these species were collected from four different sites, i.e., Control, New Lahore, Nawababad and Fatehabad. Leaf samples were analyzed to determine Pb2+, Zn2+, Ni2+, Mn2+ and Fe3+ accumulation. The A. nilotica, Z. mauritiana and C. procera accumulated significant amount of Pb at New Lahore site. Similarly, R. communis and A. nilotica accumulated higher amounts of Mn, Zn and Fe at Nawababad and New Lahore sites compared to the rest of the species. Nonetheless, Z. mauritiana accumulated higher amounts of Ni at all sites compared with the other species included in the study. Soil surface contributed towards the uptake of heavy metals in leaves; therefore, wild plant species should be grown near the roadsides to control heavy metals pollution. Results revealed that wild plants growing along roadsides accumulate significant amounts of heavy metals. Therefore, these species could be used to halt the vehicular pollution along roadsides and other polluted areas.

“…Almeida et al (2015) reported that the formation of phenols, lignin, starch and gels in plant root and stem cells serve as physical and chemical barriers which constitute the activation of multiple defense mechanisms against M. phaseolina . Moreover this plant should be further screened out for its phytochemical, medicinal and pharmacological potential by following the previously published protocol (Bahadur et al, 2020; Ijaz, Durrani, Rubab, & Bahadur, 2021; Rubab et al, 2020, 2021), ecological (Sajad et al, 2020; Shuaib, Bahadur, & Hussain, 2020) antimicrobial and phytotoxic potential (Azam et al, 2020; Shuaib et al, 2021) nanoparticles (Liaqat et al, 2021) and physiological (Iqbal et al, 2020).…”

Rapid advances in the field of pathogen detection have opened new opportunities and better understanding for their management approaches. Aim of this study was to elucidate histopathological observations of different tissues affected by Macrophomina phaseolina and to observe the defense responses of plant growth promoting rhizobacteria (PGPR) in mungbean plants. Sections of the stem and root were prepared and stained with ferric chloride, Lugol's iodine and Wiesner's reagent and were then observed under multiple microscopic techniques. Results revealed that both pathogen and PGPR produce responses on the plant that include colonization of xylem vessels by hyphae and sclerotia, hypertrophy and hyperplasia of the cells, destruction of xylem fibers and amyloplasts in parenchymatous cells; and production of gels by the plant were observed. There was a significant increase in lignin and phenolic compounds deposition in stem and root sections of PGPR treated and non‐treated mungbean plants. Whereas the soil amended with PGPR showed very less to no starch production. Moreover, production of gels and gums were also observed in both stem and root sections. Compared to light microscopy, scanning electron microscope provided greater depth of focus and resolution of the pathogen attack on plant tissues, associated bacteria. As a whole, the data demonstrated that inoculation of PGPR can be an effective strategy to stimulate plant growth and they could significantly activate disease resistance against M. phaseolina.

“…Microbial adaptation and resistance to the toxic level of pollutants are utterly vital in the bioremediation processes and heavy metal recovery application (Nanda et al., 2019). Naturally occurring biological phenomena such as Siderophores secretion, biosorption, and bioabsorption mechanisms are involved in environments or wastewaters for the adaption of toxic metals (Shuaib et al., 2021).…”

Heavy metals are extensively utilized in modern industries in various process. Subsequently a large quantity of waste generated as byproduct that have great impact on environment. A higher concentration of almost all heavy metals are toxic in nature for all living organisms. Therefore, the wastes discharged from the conventional treatment plants deteriorate the natural ecosystems; qualities of water sources and farmlands. Globally, activated sludge waste treatment technology have been widely used as a metal recovery process. The technique miscarried to attain the anticipated removal efficiency. Recently, membrane biological reactor (MBR) system has emerged as an important alternative to conventional activated sludge (CAS) systems. The work describes the potency of microbes for extraction heavy metal from wastes, the enhancements in biotechnology, characterization of specific wastes, optimization parameters to operate under various conditions that prevail in membrane bioreactors. The performance of the MBR technology shows good results to reduce all types heavy metals with supporting evidence, which obtained from the results of prominent studies.
