“…The use of parameters related to Allium cepa root growth to assess the toxicity of several substances has been increasing, because data about Allium cepa can provide information about lethal effects of the compounds, and delay in root growth can provide information about sub-lethal effects (Pantano et al, 2021). With root growth data of all treatments and negative control of a bioassay, the concentration at which 50% inhibition of root growth occurs when compared with negative control (IC50) can be estimated.…”

Cancer is the second reason for death worldwide. Conventional therapies for cancer include surgery, cytotoxic chemotherapy, immunotherapy and radiation therapy which are used as single or combinatorial therapy have some side effects (Dutta et al., 2019). Today, many plant-derived compounds "phytochemicals" have been identified that have anti-tumour properties. For example, induction of apoptosis and inhibition of cell proliferation which finally decrease the risk of cancer make these components useful for cancer treatment (Sultana et al., 2021).A simple search on Google Scholar on 21 June 2018 with the key "Allium test" produced 3170 hits, showing the wide use of the test in a variety of different investigations.A few examples are studies examining the effects of toxic plants (Pesnya et al., 2017), nanoparticles (Yekeen et al., 2017, synthetic plant hormones such as etephon (Yavuz and Kiliç, 2017), industrial waste (Dutta et al., 2018), aquatic environmental samples (Zotina et al., 2015), etc. The lethality of the test sample in a simple zoological organism like the brine shrimp (Artemia salina) has been utilised by many researchers and has proven to be a useful ARTICLE INFO

“…Allium cepa has become one of the most used model organisms in plant-based toxicity studies due to its large sized and small number of chromosomes that can be easily seen under light microscopy, easy accessibility, low cost, reliability and high correlation with other test systems 15 , 16 . Allium assay has been used for many years to elucidate the genotoxic effects of pesticides in living organisms 17 , 18 .…”

The excessive use of metaldehyde in agriculture to combat mollusks endangers both the environment and non-target organisms. The aim of this study is to investigate the toxicity caused by metaldehyde in Alliumcepa with the help of physiological, cytogenetic, biochemical and anatomical parameters. Also, DNA fragmentation caused by metaldehyde in root tip cells was measured by the "Comet Assay" method. The control group was germinated with tap water and the application groups were germinated with 20 mg/L metaldehyde, 40 mg/L metaldehyde, 100 mg/L metaldehyde and 200 mg/L metaldehyde for 72 h. The results of the physiological parameters showed that metaldehyde had a growth-limiting effect in A.cepa, depending on the application dose. According to root elongation levels, the EC50 (effective concentration) value for metaldehyde was 60.6 mg/L in A.cepa. As the treatment dose increased, the incidence of micronucleus and chromosomal aberrations gradually increased while mitotic index decreased. Metaldehyde exposure induced damages such as sticky chromosome, fragment, unequal distribution of chromatin, reverse polarization, bridge, and multipolar anaphase. In addition, metaldehyde caused cell damage in epidermis and cortex, thickening of the cortex cell wall and flattened cell nucleus in root meristem. Increasing doses of metaldehyde application also increased malondialdehyde levels, superoxide dismutase and catalase activities. As a result, it has been determined that the toxicity of metaldehyde in plants is versatile and the A.cepa test material is a suitable biological indicator to determine this toxicity.

“…Furthermore, Allium cepa is the most widely used higher plant for the investigation of early damage by single‐cell gel electrophoresis (or comet) assay (Alias, Zerbini, & Feretti, 2023). Because of these characteristics, Allium cepa is widely applied to determine the cytotoxicity and genotoxicity of soil contaminants such as pesticides (Rosculete et al, 2019), veterinary drugs (de Souza et al, 2022), biosorbents (Pantano et al, 2021), as well as the phytotoxicity and genotoxicity of different sludges (Santos et al, 2022).…”

The potential impact of concrete mixtures containing steel slag (SS) as a partial replacement of natural aggregates (NA) on the terrestrial ecosystem was assessed using a battery of plant‐based bioassays. Leaching tests were conducted on four concrete mixtures and one mixture containing only NA (reference concrete). Leachates were tested for phytotoxicity using seeds of Lepidium sativum, Cucumis sativus, and Allium cepa. Emerging seedlings of L. sativum and A. cepa were used to assess DNA damage (comet test). The genotoxicity of the leachates was also analyzed with bulbs of A. cepa using the comet and chromosome aberration tests. None of the samples caused phytotoxic effects. On the contrary, almost all the samples supported the seedlings; and two leachates, one from the SS‐containing concrete and the other from the reference concrete, promoted the growth of C. sativus and A. cepa. The DNA damage of L. sativum and A. cepa seedlings was significantly increased only by the reference concrete sample. In contrast, the DNA damage in A. cepa bulbs was significantly enhanced by the reference concrete but also by that of a concrete sample with SS. Furthermore, all leachates caused an increase in chromosomal aberrations in A. cepa bulbs. Despite some genotoxic effects of the concrete on plant cells, the partial replacement of SS does not seem to make the concrete more hazardous than the reference concrete, suggesting the potential use of SS as a reliable recycled material.
