“…The creation of fluctuating potentials, long-term depolarization in heart Purkinje fibers, and apoptosis of stem cells are the mechanisms of the destructive effect of Sr on the heart [ 41 ]. Sr, which is found in food, soil, and water, has a half-life of fewer than 3 years and belongs to the alkaline earth group [ 42 ]. The most important way to bury it from the body is through urine; As a result, urine is an important biomarker for measuring the amount of calcium received by the body.…”

“…Studies on the inhibition of plant photosynthesis by heavy metals have also been reported [64][65][66]. Whether CK or inoculation treatment was received, Pn generally decreased with the increase in Mo stress, indicating that the Mo toxicity inhibited the ability of maize to assimilate carbon [67].…”

The use of arbuscular mycorrhizal fungi (AMF) is a vital strategy for enhancing the phytoremediation of heavy metals. However, the role of AMF under molybdenum (Mo) stress is elusive. A pot culture experiment was conducted to explore the effects of AMF (Claroideoglomus etunicatum and Rhizophagus intraradices) inoculation on the uptake and transport of Mo and the physiological growth of maize plants under different levels of Mo addition (0, 100, 1000, and 2000 mg/kg). AMF inoculation significantly increased the biomass of maize plants, and the mycorrhizal dependency reached 222% at the Mo addition level of 1000 mg/kg. Additionally, AMF inoculation could induce different growth allocation strategies in response to Mo stress. Inoculation significantly reduced Mo transport, and the active accumulation of Mo in the roots reached 80% after inoculation at the high Mo concentration of 2000 mg/kg. In addition to enhancing the net photosynthetic and pigment content, inoculation also increased the biomass by enhancing the uptake of nutrients, including P, K, Zn, and Cu, to resist Mo stress. In conclusion, C. etunicatum and R. intraradices were tolerant to the Mo stress and could alleviate the Mo-induced phytotoxicity by regulating the allocation of Mo in plants and improving photosynthetic leaf pigment contents and the uptake of nutrition. Compared with C. etunicatum, R. intraradices showed a stronger tolerance to Mo, which was manifested by a stronger inhibition of Mo transport and a higher uptake of nutrient elements. Accordingly, AMF show potential for the bioremediation of Mo-polluted soil.

“…AT3G04590 (homologous gene of BrAHL24) was found to have interactions with far-red elongated hypocotyls (FRSs) in regulating the light control of plant development. Notably, photosynthesis is the primary process affected by stress conditions, e.g., heavy metal stress [30][31][32]. It can be speculated that BrAHL24 participates in heavy metal stress tolerance (Figure 9C).…”

The AT-hook motif nuclear localized (AHL) gene family is a highly conserved transcription factor critical for the growth, development, and stress tolerance of plants. However, the function of the AHL gene family in Brassica rapa (B. rapa) remains unclear. In this study, 42 AHL family members were identified from the B. rapa genome and mapped to nine B. rapa chromosomes. Two clades have formed in the evolution of the AHL gene family. The results showed that most products encoded by AHL family genes are located in the nucleus. Gene duplication was common and expanded the BrAHL gene family. According to the analysis of cis-regulatory elements, the genes interact with stress responses (osmotic, cold, and heavy metal stress), major hormones (abscisic acid), and light responses. In addition, the expression profiles revealed that BrAHL genes are widely expressed in different tissues. BrAHL16 was upregulated at 4 h under drought stress, highly expressed under cadmium conditions, and downregulated in response to cold conditions. BrAHL02 and BrAHL24 were upregulated at the initial time point and peaked at 12 h under cold and cadmium stress, respectively. Notably, the interactions between AHL genes and proteins under drought, cold, and heavy metal stresses were observed when predicting the protein-protein interaction network.
