“…In the present experiment, the application of bio-fertilizers (alone and in combination) was found favourable to abate the cadmium stress in coriandrum sativum. These results are in consistent withthe previous works that cadmium had a toxic effect on growth whereas addition of bio-fertilizer helps in promoting growth under cadmium stress [67][68][69][70][71]. The presence of cadmium in the soil inhibits plants growth by altering the plant metabolism even at low concentration [72].…”

The aim of the present study was to evaluate the role of arbuscular mycorrhizal (AM) fungi and Azotobacteron growth, oxidative effect and antioxidant defense mechanisms under cadmium (Cd) stresses in Coriandrum sativum L. (Coriander). Treatments consisted of mycorrhizal and Azotobacter treatments and threeconcentrations of cadmium treatments (0,50and 100 mg Cd kg-1 of soil). Metal induced oxidative damage through increased lipid peroxidation. Superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) increased under stress and it was found that there was a direct correlation between root length, shoot length, plant fresh weight and plant dry weight and the activity of these enzymes in concentration dependent manner. The activity of antioxidants and growth increased in mycorrhizal and Azotobacter stressed plants. However, the combination of mycorrhiza (AMF) and Azotobacteracted synergistically and significantly arrested lipid peroxidation and led to increased growth as well as activity of activity of antioxidants. The interactions of cadmium and biofertilizers proved to be synergistic and the antioxidant activities further increased indicated the positive role of biofertilizers in increasing the antioxidant activity thereby decreasing oxidative stress and stimulating growth. Therefore, biofertilizers are advisable to enhance the tolerance to cadmium stress in medicinally important coriander.

“…We can speculate that it is most likely due to the growth promoting effects of PGPRs as well as enhanced protein levels that in turn stimulated the pigment levels. Several studies of PGPRs in enhancing the levels of chlorophyll and carotenoids under Cd stress have been reported such as Proteus vulgaris in pigeon pea 65 , Enterobacter in rice 47 , Azotobacter in Plantago ovata 66 , and K . pneumoniae in rice 53 .…”

Plant growth promoting rhizobacteria (PGPRs) are very effective in immobilization of heavy metals and reducing their translocation in plants via precipitation, complex formation and adsorption. The present study was therefore designed to understand the role of Pseudomonas aeruginosa and Burkholderia gladioli in mitigation of Cd stress (0.4 mM) in 10-days old L . esculentum seedlings. The present work investigated growth characteristics, photosynthetic pigments, metal tolerance index, metal uptake and the contents of metal chelating compounds (protein bound and non-protein bound thiols, total thiols) in microbes inoculated Cd treated L . esculentum seedlings. The gene expression profiling of different metal transporters was conducted in order to investigate the quantitative analysis. Our results revealed Cd generated toxicity in seedlings in terms of reduced growth (root length, shoot length and fresh weight) and photosynthetic pigments (chlorophyll, carotenoid and xanthophyll) which enhanced upon inoculations of P . aeruginosa and B . gladioli . Further, the metal uptake along with levels of protein and non-protein bound thiols was also enhanced in Cd-treated seedlings. Gene expression studies suggested enhanced expression in the metal transporter genes which were further declined in the microbe supplemented seedlings. Therefore, micro-organisms possess growth promoting traits that enable them to reduce metal toxicity in plants.

“…This result was in harmony with Abdelhameed and Metwally (2019), who demonstrated that increasing cadmium rates lead to decreased shoot and root growth of fenugreek plants. In the same line, several researchers stated that a negative impact on root system with rising utilization rate of Cd (Haneef, Faizan, Perveen, & Kausar, 2014) and Pb (Amanifar et al., 2014) in soil.…”

This research was carried out to investigate the impact of A‐mycorrhizal fungi (AMF) and rock phosphate (RP) (alone and combined) under polluted soil with lead (Pb) and cadmium (Cd) on maize plant growth and soil nutrients availability under calcareous soil conditions. A greenhouse pot experiment was designed as a two‐factor experiment, remediation sources (RS) as the sub‐main factor with four treatments [control, M (mixed of the two mycorrhizae species, Rhizoglomus irregulare and Rhizoglomus macrocarpium), RP, and M + RP], and soil pollution sources (PS) as the main factor with nine treatments [control, Pb1 (100 mg Pb /kg soil), Pb2 (500 mg Pb/kg soil), Cd1 (6 mg Cd/kg soil), Cd2 (24 mg Cd/kg soil), Pb1 + Cd1, Pb1 + Cd2, Pb2 + Cd1, Pb2 + Cd2]. The results showed that, under the same conditions of this study, we can recommend the use of coapplication of AMF and RP (M + RP) particularly in contaminated soil with Pb and/or Cd, which supports plants to (i) confront the pollution stress, (ii) improve plants growth and their nutrients content, and (iii) increase the soil available nutrients. Also, maize plants could be labeled as the accumulator of Pb based on (translocation factor > 1) as control and under calcareous soil conditions.
