“…As a zinc sensitive crop, maize is signi cantly affected by zinc, and the difference between concentration gradients is signi cant. Low concentration of zinc promotes growth, high concentration inhibits growth, and medium concentration is in a transition state (Wang 2008). In addition to the toxic effects on crops themselves, the most important thing is that these crops accumulate in the human body through the food chain after being consumed by humans, which can cause serious health and safety issues (Nordberg 2009).…”

Excessive levels of Zn have the potential to be detrimental to plant health. ZmHMA3, a member of the heavy metal ATPase (HMA) family, is responsible for the transport of Zn2+ and Cd2+ across cellular membranes. In order to investigate the role of the ZmHMA3 gene in response to Zn stress, ZmHMA3 knockout mutants were created using the CRISPR-Cas9 technique. Subsequently, gene specific expression, as well as agronomic traits, root morphology indicators, relative conductivity, antioxidant indicators, and Zn content in the leaf, root, and their subcellular components were assessed. The results demonstrated a significant accumulation of ZmHMA3 in both the leaf and root after 48 hours of Zn stress compared to the control group. The Zmhma3 knockout line exhibited decreased tolerance to toxic levels of Zn as compared to the wild type, resulting in a reduction in maize plant height, fresh weight, dry weight, water content, root morphology indicators (Length, SurfArea, AvgDiam, Rootvolume, Tips and Forks) and antioxidant enzyme activity (CAT, POD, SOD, and MDA), while also leading to an increase in membrane permeability and zinc accumulation. In conclusion, it can be inferred that ZmHMA3 likely functions as a crucial positive regulator in the response to Zn stress in maize.

Maize ((Zea mays L.) is one of the three major grains in the world, widely cultivated globally. Heavy metal Zn pollution poses great risks to corn growth and food security, posing a serious threat to the environment and human health. HMA belongs to the transport protein of the heavy metal ATPase family and can transport Zn2+ and Cd2+ across membranes. To identify the gene function of maize ZmHMA3 in response to Zn pollution, this study constructed a CRISPR-Cas9 mediated ZmHMA3 knockout mutant, using maize inbred line B104 as the genetic background. Under heavy metal Zn stress, gene specific expression, subcellular localization, agronomic traits, root morphology indicators, antioxidant indicators, and Zn content in various parts and subcellular components of cells were measured. Zmhma3 reduced various growth indicators (plant height, fresh weight, dry weight, and water content) and root morphology indicators of maize, decreased antioxidant enzyme activity, increased membrane permeability, and increased zinc accumulation. Various parameters indicate that under Zn stress, Zmhma3 exhibits weaker tolerance than WT, demonstrating the positive regulatory role of the ZmHMA3 gene in Zn stress. These have laid the foundation for exploring the regulatory mechanisms of plants in response to Zn pollution in the future.

“…can be considered as phytostabilization material. Erigeron annuus (L.) Pers [49], Periploca sepium Bunge [50] are common weeds with strong vitality, which have strong adaptability to soil environmental stress. Once settled, they can quickly cover the surface, form dense roots underground, and improve the surrounding habitat.…”

Soil arsenic (As) pollution in mining areas have seriously affected the surrounding environment and human health. To explore the degree of soil As contamination and phytoremediation strategies, a study was undertaken to identify suitable native plants for the phytoremediation in mining area. Geo-accumulation index and potential ecological risk index were sed to assess the As pollution degree. As content in dominant plants was analyzed by enrichment coefficient. The results show that (1) The pulp deposition area had the most serious As pollution of soil and the largest potential ecological risk index. (2) The composition of the plant community in the study area was dominated by herbaceous plants, among which gramineous, composites and legumes are the dominant plant types in the vegetation community restoration in the mining area. (3) The plant species diversity was lower in As polluted area. (4) The plants with strong As enrichment ability were Erigeron annuus (L.) Pers., Periploca sepium Bunge, and Setaria viridis (L.) Beauv., which can be considered as As-repair plants. This study can provide a basis and reference for phytoremediation and ecological restoration of As contamination in mining areas.
