Abstract

Bisphenol A (BPA) is a common chemical used in plastic production. BPA, which has the potential to be poisonous to plants, has lately emerged as a serious environmental concern owing to its extensive usage and release patterns. Prior study has only looked at how BPA affects plants up to a certain stage in their growth. The precise mechanism of toxicity, penetration of BPA, and damage to internal root tissues remains unknown. Therefore, the goal of this study was to examine the hypothesized mechanism for BPA-induced root cells by studying the effects of bisphenol A (BPA) on the ultrastructure and function of root tip cells of soybean plants. We looked at plant changes in root cell tissues after BPA exposure. Further, the biological characteristics that responded to BPA stress were investigated, and the accumulation of BPA in the root, stem, and leaf of the soybean plant was systematically investigated by using FTIR and SEM analysis. The uptake of BPA is a key internal factor that contributes to changes in biological characteristics. Our findings provide insight into how BPA could alter plant root growth, which might contribute new knowledge toward a better scientific appraisal of the possible dangers of BPA exposure for plants.

摘要

双酚A(BPA)是塑料生产中常用的一种化学物质。双酚A可能对植物有毒,由于其广泛的使用和释放模式,最近已成为一个严重的环境问题。先前的研究仅考察了双酚A在植物生长的特定阶段之前对其的影响。毒性的确切机制、双酚A的渗透以及对根部内部组织的损害仍然未知。因此,本研究的目的是通过研究双酚A(BPA)对大豆根尖细胞超微结构和功能的影响,来检验双酚A诱导根细胞的假设机制。我们观察了双酚A暴露后根细胞组织中的植物变化。此外,研究了对双酚A胁迫作出反应的生物学特性,并通过傅里叶变换红外光谱(FTIR)和扫描电子显微镜(SEM)分析系统地研究了双酚A在大豆植株根、茎和叶中的积累情况。双酚A的吸收是导致生物学特性变化的一个关键内在因素。我们的研究结果深入了解了双酚A如何改变植物根系生长,这可能为更好地科学评估双酚A暴露对植物可能造成的危害贡献新知识。
