“…In this work, 2500 mg L −1 of Cr(VI) (∼1980 mg kg −1 soil) was required to prevent Prosopis laevigata germination, highlighting the heavy metal tolerance of Prosopis. The high Cr concentration tested (2500 mg L −1 ) is 19-fold higher than those found in polluted soils (Amin et al, 2019); showing the bioremediation potential of using P. laevigata in combination with Bacillus sp. MH778713 for soil restoration of sites contaminated with Cr.…”

“…Although seed coat provides protection, some metals can permeate into the seed before germination or diffuse into the embryo upon seed-coat cracking leading to alterations into nitrogen and carbohydrate metabolism, water uptake, oxidative stress, and seed germination (Kranner and Colville, 2011;Yıldız and Terzi, 2016;Kaszycki et al, 2018). Elevated Cr(VI) concentrations (75-100 mg kg −1 soil) inhibit seed germination, reduce chlorophyll contents and affect most of the growth parameters of biofuel plant species (Amin et al, 2019). In this work, 2500 mg L −1 of Cr(VI) (∼1980 mg kg −1 soil) was required to prevent Prosopis laevigata germination, highlighting the heavy metal tolerance of Prosopis.…”

“…The most ubiquitous oxidation states of Cr in nature are trivalent (Cr III) and hexavalent (Cr VI) chromium; being Cr(VI) the most phytotoxic (Panda and Choudhury, 2005). Chromium(VI) at concentrations ranged 50-100 mg kg −1 soil are toxic for most plants affecting germination rate, chlorophyll content, and most of the growth parameters (Akinci and Akinci, 2010;Jain et al, 2016;Amin et al, 2019). For plants growing in a nutrient solution, 10-25 mg L −1 Cr VI is detrimental for plant development (Dube et al, 2003;Ramírez et al, 2019).…”

Volatile organic compounds (VOCs) produced by rhizobacteria have been proven to stimulate plant growth during germination and seedling stages. However, the modulating effect of bacterial volatiles on the germination of seeds subjected to heavy metal stress is scarcely studied. In this work, the ability of volatiles released by Bacillus sp. MH778713 to induce seed dormancy breakage in Prosopis laevigata and Arabidopsis thaliana seeds were examined. The minimal inhibitory concentration of chromium (Cr) VI that prevents seed germination of P. laevigata and A. thaliana on water-Cr-agar plates was 2500 and 100 mg L −1 , respectively. Remarkably, partitioned Petri-dish co-cultivation of Bacillus sp. MH778713 and plant seeds under Cr-stress showed the beneficial effect of volatiles emitted by Bacillus sp. MH778713, helping plant seeds to overcome Cr-stress. Among the metabolites emitted by Bacillus sp. MH778713, octadecane, heneicosane, 2,4-di-tert-butylphenol, hexadecane, eicosane, octacosane, and tetratriacontane were the most abundant. To confirm that these long-chain compounds produced by Bacillus sp. MH778713 could be responsible for the seed dormancy breakage, high pure organic compounds (2,4-di-tert-butylphenol, heneicosane, hentriacontane, and tetracosane) were used directly in germination assays of P. laevigata and A. thaliana seeds instead of volatiles emitted by Bacillus sp. MH778713. All organic compounds allowed Prosopis and Arabidopsis seeds to overcome Cr-toxicity and germinate. The results of this study provide new insight into the role of long-chain bacterial compounds produced by Bacillus sp. MH778713 as triggers of seed abiotic stress tolerance, surmounting chromium stress and stimulating seedling development.

“…In our study, Cr(VI) negatively affected the growth of hybrid Napier grass and reduced the plant yield and biomass in dose-dependent manner. The adverse effects of Cr(VI) on plant growth have been well documented [27,28,29]. A reduction in biomass and plant yield is caused by the stunted growth of shoot and leaf, which might be due to the toxic effects of Cr(VI) on photosynthesis and it might be partially due to a reduced transport of water and nutrients from soil caused by reduced root growth in presence of Cr(VI) [22,28].…”

Hexavalent chromium [Cr(VI)] contamination has become an emergent concern in China. Previous field investigations have found that hybrid Napier grass is widely distributed in Cr(VI) contaminated areas. This study investigated the phytoremediation potential and biochemical response of hybrid Napier grass (Pennisetum americanus L. × Pennisetum purpureum Schumach) grown in soil contaminated with Cr(VI) (0, 20, 40, and 60 mg kg−1) with and without Ethylene diamine tetra acetic acid (EDTA) (4 mM) application. The results indicated that root length, shoot height, dry weight, leaf area, chlorophyll, and photosystem II (PSII) parameters viz.; apparent electron transport rate (ETR), effective quantum yield of PSII (ΦPSⅡ), maximal PSII photochemical efficiency (Fv/Fm), potential activity of PSII (Fv/Fo), photochemical quenching (qP), and non-photochemical quenching (qN) decreased with the increasing Cr(VI) concentration. EDTA application further aggravated reduction of dry biomass and photosystem II. The concentration and the accumulation of Cr in shoot and root, and both the bioaccumulation factor (BAF) and transfer factor (TF) increased with increasing Cr(VI) concentrations and further enhanced with EDTA application. Though the Cr(VI) and Ethylene diamine tetra acetic acid (EDTA) stress reduced tolerance, but, even at highest Cr(VI) concentration, plant could exhibited strong resistance, as evidenced by increase in superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activities. Hybrid Napier grass, due to its BAF > 1 and a TF < 1, would be applicable for Cr phytostabilization. Moreover, limiting metal transport to aerial parts of plant would prevent animal’s ingestion, restrict soil mobility, and consequently reduce transmission across the food chain.

Aim. Determination of the effect of toxic metals on plants is of considerable interest, since contamination of the environment with toxicants is a threat to the safety of agriculture and human health. Vanadium increased content in soil leads to the suppression of plant growth. The aim of the work was to determine the peculiarities of the influence of V(IV) (neutral solution [V4+ cit]) on Artemisia tilesii Ledeb plants in the in vitro model system and to compare this effect on the growth of “hairy” root culture and plants. Methods. Plant shoots and transgenic roots were cultivated on a solidified Murashige and Skoog medium with V(IV) at 1, 5, 10, 50 and 100 mg/L. Mass increase was measured after 4 weeks. Results. It was found that V(IV) at 50 mg/L concentration completely inhibited root formation and led to shoot death. Transgenic roots survived even at 100 mg/L of vanadium. Conclusions. The results of the work demonstrated that A. tilesii “hairy” roots were characterized by greater resistance to V(IV) than control plants. In addition, differences in the sensitivity of different root lines to this compound were detected. This fact probably could be explained by the transformation, the transfer of agrobacterial genes, and changes in the secondary metabolism in transgenic roots. Keywords: vanadium(IV), Artemisia tilesii Ledeb., “hairy” root culture.
