“…Rydzy ński et al [41] showed tetracycline accumulation (123 µg × fresh weight −1 ) in yellow lupin seedlings, resulting in a reduction in plant fresh weight. These results were confirmed by Rydzy ński et al [23]. The authors showed tetracycline accumulation in spinach seedlings, which correlated with a decrease in fresh weight content.…”

“…The reduction of the chlorophyll content in the plants subjected to tetracycline treatment has been observed repeatedly [23,41,47]. Margas et al [47] have shown that in peas exposed to 250 mg × L −1 tetracycline, a 37% decrease in chlorophyll content occurred.…”

“…The presence of antibiotics in the environment causes toxic effects in the organisms against which they are not targeted, e.g., plants. It has also been shown that tetracycline degrades chlorophyll in plants [23], disrupts the flow of electrons in photosystems [24], and causes the overproduction of free radicals and peroxidation of membrane lipids [25]. These disturbances result in the inhibition of plant growth.…”

In this study, the ability of Lemna minor L. to recover to normal growth, after being degraded in a tetracycline-containing medium, was extensively investigated. The plants were exposed to tetracycline (TC) at concentrations of 1, 2.5, and 10 mM. Subsequently, their physiological status was analysed against the following criteria: rate of plant growth; free radical accumulation; antioxidant enzyme activity; chlorophyll content; HSP70 protein content; cell membrane permeability, and mitochondrial activity. The study showed that duckweed can considerably recover from the damage caused by antibiotics, within a week of cessation of stress. Of the plant properties analysed, mitochondrial activity was the most sensitive to antibiotic-induced disturbances. After transferring the plants to a tetracycline-free medium, all plant parameters improved significantly, except for the mitochondrial activity in the plants grown on the medium containing the highest dose of tetracycline. In the plants treated with this antibiotic at the concentration of 10 mM, the proportion of dead mitochondria increased and was as high as 93% after one week from the beginning of the recovery phase, even after the transfer to the tetracycline-free medium.

“…Photosynthetic pigment is a basic parameter for evaluating photosynthetic activity which is often used as an indicator of plant damage under adversity stress (Liu and Wu, 2018). Many studies have shown that tetracyclines can signi cantly reduce chlorophyll contents (Rydzyński et al, 2019;Siedlewicz et al, 2020b). Tetracyclines mainly affect chlorophyll contents by inhibiting chloroplast translation activity and the activities of enzymes related to chlorophyll molecule synthesis (Kasai et al, 2004).…”

Tetracyclines are frequently detected in water bodies due to their widespread use in aquaculture and animal husbandry. A hydroponic experiment was conducted to explore the phytotoxic effects of Vallisneria natans (Lour.) Hare exposed to various concentrations of chlortetracycline (CTC) and oxytetracycline (OTC) (0, 0.1, 1, 10, 30, 50 and 100 mg/L) for 7 days (7 D) and 14 days (14 D), respectively. The results showed that similar to OTC treatment for 7 D, the relative growth rates (RGR) and catalase (CAT) activity of V. natans , after 7 D of CTC exposure, decreased signi cantly at 10 mg/L and 30 mg/L, respectively. The content of soluble protein notably decreased when CTC ≥ 10mg/L and OTC ≥ 30mg/L. The hydrogen peroxide (H 2 O 2 ) content was signi cantly stimulated when OTC ≥ 10mg/L, while it hardly changed when exposed to CTC. After 14 D, the malondialdehyde (MDA) and H 2 O 2 contents of V. natans were signi cantly higher than those of the control group under high concentration of OTC (≥ 30mg/L), but they didn't change signi cantly under high concentration of CTC. The activity of polyphenol oxidase (PPO), under CTC treatment after 14 D, showed rst a signi cant increase then decrease, the maximum value (125% of the control) was notice at 10 mg/L CTC, while it remained unchanged when exposed to OTC. The soluble protein content signi cantly decreased at 10 mg/L CTC and 0.1 mg/L OTC, respectively. The RGR, CAT and peroxidase (POD) activities, similar to OTC treatment after 14 D, decreased evidently when CTC was 10 mg/L, 30 mg/L and 0.1 mg/L, respectively. CTC and OTC harm the chlorophyll content of V. natans after 14 D, and the reduction of chlorophyll a and carotenoid were more pronounced than chlorophyll b. The results suggest that CTC and OTC both have negative effect on the growth of V. natans , and OTC can cause oxidative damage in V. natans but CTC harm the metabolism process without inducing oxidative damage. Overall, the toxicity of OTC to V. natans is stronger than that of CTC.

“…In addition, CTC is known to interact with cations, such as Mg 2+ and Ca 2+ [44], and thus may contribute to Chl breakdown via the dechelation of Mg 2+ in the Chl molecule [31,45]. It is therefore possible that CTC itself is involved in Chl breakdown, thereby directly reducing Chl content [46].…”

Different Inhibitory Effects of Erythromycin and Chlortetracycline on Early Growth of Brassica campestris Seedlings

et al. 2021

Veterinary antibiotics, including erythromycin (Ery) and chlortetracycline (CTC), are often detected in agricultural land. Although these contaminants affect plant growth and development, their effects on crops remain elusive. In this study, the effects of Ery and CTC on plant growth were investigated and compared by analyzing transcript abundance in Brassica campestris seedlings. Treatment with Ery and/or CTC reduced chlorophyll content in leaves and photosynthetic efficiency. Examination of the chloroplast ultrastructure revealed the presence of abnormally shaped plastids in response to Ery and CTC treatments. The antibiotics produced similar phenotypes of lower accumulation of photosynthetic genes, including RBCL and LHCB1.1. Analysis of the transcript levels revealed that Ery and CTC differentially down-regulated genes involved in the tetrapyrrole biosynthetic pathway and primary root growth. In the presence of Ery and CTC, chloroplasts were undeveloped and photosynthesis efficiency was reduced. These results suggest that both Ery and CTC individually affect gene expression and influence plant physiological activity, independently of one another.
