“…The stimulatory effect of low BPA-concentration on chlorophyll accumulation has been observed in other plants, especially in soybean seedlings (Hu et al, 2014). BPA (1.5 mg/l) increases the activity of five enzymes, involved in chlorophyll biosynthesis (Jiao et al, 2015;Jiao et al, 2017). The positive effect of BPA on chlorophyll accumulation is probably not a result of its estrogenic activities, as low-dose heavy metal concentrations also increase chlorophyll content in plants (Maleva et al, 2009;Kumar et al, 2015).…”

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.

“…Previous research reported that the long-term leaf irrigation with BPA solution decreases chlorophyll content of leaves 6 , 7 . In this study, there is no significant change in chlorophyll content among the different treatments (Table 1 ), which indicates that the inactivation of photosynthetic apparatus (Figs 1 – 5 ) caused by BPA is independent of the degradation of pigments.…”

“…Some studies showed that the low concentrations of BPA promote the growth of soybean and carrot, however, high concentrations inhibited seed germination and root growth of broad bean, tomato, and durum wheat 5 . In addition, BPA obviously restrains the biosynthesis of chlorophyll 6 and restrains photosynthesis 7 . It also decreases the biomass of shoot, leaf area and net photosynthetic rate 8 .…”

Bisphenol A (BPA), a widely distributed pollutant, suppresses photosynthesis in leaves. In previous studies on higher plants, the plants were treated by BPA through irrigation to root. This method cannot distinguish whether the BPA directly suppresses photosynthesis in leaves, or indirectly influences photosynthesis through affecting the function of root. Here, only the leaves but not the roots of cucumber were infiltrated with BPA solution. The photosystem II and I (PSII, PSI) were insensitive to BPA under darkness. BPA aggravated the PSII but not the PSI photoinhibition under light. BPA also inhibited CO2 assimilation, and the effect of BPA on PSII photoinhibition disappeared when the CO2 assimilation was blocked. The H2O2 accumulated in BPA-treated leaves under light. And the BPA-caused PSII photoinhibition was prevented under low (2%) O2. We also proved that the BPA-caused PSII photoinhibition depend on the turnover of D1 protein. In conclusion, this study proved that BPA could directly suppress photosynthesis in leaves, however, BPA does not damage PSII directly, but inhibits CO2 assimilation and over-reduces the electron transport chain under light, which increases the production of reactive oxygen species (H2O2), the over-accumulated ROS inhibits the turnover of D1 protein and consequently aggravates PSII photoinhibition.

“…Soybean ( Glycine max , Zhonghuang 25) seeds were germinated in accordance with previously reported methods 19 . Thirty days after germination, when there were both flowers and young raised pods (approximately 2 cm) in the soybean plants, the soybean plants were transplanted into BPA solutions at different doses (0.0, 1.5, 6.0, and 12.0 mg·L −1 ).…”

“…Recently, the effects of BPA on algae have been frequently reported 12 13 , but the effects of BPA on terrestrial plants are less studied 14 , and the microscopic mechanism of BPA on plants remains unclear 15 . Previous studies showed that certain doses of BPA exposure could promote or inhibit the growth 15 16 , germination 17 , pollen tube elongation 18 , photosynthesis 19 , and hormone contents 20 in plants. As a vital organ of plants in long-term adaptations to land, roots can absorb water and nutrients from soil for plant growth and development 21 , and roots also have the ability to absorb, fix and transfer pollutants.…”

Bisphenol A (BPA) is an important industrial raw material. Because of its widespread use and increasing release into environment, BPA has become a new environmental pollutant. Previous studies about BPA’s effects in plants focus on a certain growth stage. However, the plant’s response to pollutants varies at different growth stages. Therefore, in this work, BPA’s effects in soybean roots at different growth stages were investigated by determining the reactive oxygen species levels, membrane lipid fatty acid composition, membrane lipid peroxidation, and antioxidant systems. The results showed that low-dose BPA exposure slightly caused membrane lipid peroxidation but didn’t activate antioxidant systems at the seedling stage, and this exposure did not affect above process at other growth stages; high-dose BPA increased reactive oxygen species levels and then caused membrane lipid peroxidation at all growth stages although it activated antioxidant systems, and these effects were weaker with prolonging the growth stages. The recovery degree after withdrawal of BPA exposure was negatively related to BPA dose, but was positively related to growth stage. Taken together, the effects of BPA on antioxidant systems in soybean roots were associated with BPA exposure dose and soybean growth stage.
