“…Unlike root, shoot growth was severely inhibited by the soil contamination at 1000 mg.kg -1 BPA. Our findings are in agreement with several studies which reported that BPA disturbs the shoot development of various species including wheat with reduction of leaf biomass, area or anatomy abnormalities (Ali et al 2016;Frejd et al 2016;Staples et al 2010). Exposure to BPA was also reported to reduce shoot growth more than root growth for Vigna radiata in another experiment using artificially contaminated soil (Kim et al 2018).…”

Repeated application of organic fertilizer has unintentionally let to the introduction into surface water and soils of many phytotoxic substances that compromise agricultural production and threaten environmental quality. Recent studies using hydroponic systems have reported that bisphenol A (BPA) affects essential mineral elements contents and root absorptive function, thereby impacting nutrient content in plant. However, in soils, plants develop specific traits related to nutrient acquisition strategies. In order to ensure optimized supply of nutrients, understanding the response of these traits under BPA stress is thus essential. Here, we therefore, investigated how leaf nutrient contents (P, Ca, K), root morphology, P-mobilizing exudates and rhizospheric microbiota biomass respond to BPA soil contamination using wheat (Triticum aestivum) as plant model. After 7 weeks, root and leaf traits were not markedly affected by the exposure to BPA at low and high concentrations (0.1 and 1000 mg. kg-1 soil). Significant change on average root diameter and aerial biomass were only observed at the highest dose. BPA contamination had no influence on nutrients acquisition traits and root associated microbiota. Specific root length, carboxylates exudation and P, Ca, K concentrations in leafs were similar irrespective of the treatments. In addition, total microbial biomass, bacteria and fungi abundance measured by phospholipid fatty acid analysis did not differ among controls and contaminated soils. In summary, this experiment suggests a limited influence of BPA contaminated soils on traits involved in nutrient acquisition in wheat.

“…Estrogens also have a negatively affect on auxin content (Kopcewicz, 1970a). Notably, auxins and ethylene are hormones involved in the control of flowering and it was suggested, that BPA may interfere negatively with auxin regulation, as well as decrease the expression of particular ethylene-and auxin-dependent genes (Tian et al, 2014;Frejd et al, 2016).…”

Bisphenol A (BPA) is a widely used chemical, that can potentially be toxic to plants. In this study we examined the toxicity of 5-50 mg/l of BPA on Arabidopsis thaliana. Additionally, the effects of 0.5-5 mg/l of BPA were examined after four weeks of development. BPA had no effect on the germination rate and the chlorophyll a/b ratio. The chlorophyll a and carotenoid content was significantly elevated in seedlings treated with 5 mg/l of BPA. In 4-week-old plants there was no change in the chlorophyll and carotenoid content and photosynthetic parameters (F/F, F/F and PI) were unaffected, which suggests no photoinhibition. No oxidative stress symptoms were observed. BPA significantly decreased leaf protein content. A low concentration of BPA seems to have no significant effect on A. thaliana flowering, but further investigation is needed. The results obtained indicate that a low concentration of BPA has no negative effect on the growth and development of A. thaliana.

“…In soybean, root growth and auxin (IAA) increased at 1.5 ppm BPA, while both were reduced at over 3 ppm BPA (Li et al, 2018b;Wang et al, 2015). In addition, the expression level of auxin signaling gene ACS11 encoding a 1-amino-cyclopropane-1-carboxylate synthase 11 was reduced by over 10 nM BPA in Arabidopsis (Frejd et al, 2016).…”

Bisphenol A (BPA) is a harmful environmental contaminant acting as an endocrine disruptor in animals, but it also affects growth and development in plants. Here, we have elucidated the functional mechanism of root growth inhibition by BPA in Arabidopsis thaliana using mutants, reporter lines and a pharmacological approach. In response to 10 ppm BPA, fresh weight and main root length were reduced, while auxin levels increased. BPA inhibited root growth by reducing root cell length in the elongation zone by suppressing expansin expression and by decreasing the length of the meristem zone by repressing cell division. The inhibition of cell elongation and cell division was attributed to the enhanced accumulation/redistribution of auxin in the elongation zone and meristem zone in response to BPA. Correspondingly, the expressions of most auxin biosynthesis and transporter genes were enhanced in roots by BPA. Taken together, it is assumed that the endocrine disruptor BPA inhibits primary root growth by inhibiting cell elongation and division through auxin accumulation/redistribution in Arabidopsis. This study will contribute to understanding how BPA affects growth and development in plants.
