AB  - Assessment of impact of pollution in the environmental studies requires multi-endpoints approach to properly
link cause and effects of pollution with focus on chemical pollution. In this sense systematic weight-of-evidence
approach (WoE) with multiple lines of evidence (LoEs) is preferable to apply. The WoE approach highlights the
importance to identify strengths and weaknesses of used LoEs. Therefore, in this study we have tested efficacy
of genotoxicological endpoints as one of the LoEs in the in situ assessment of pollution effects in the freshwater
ecosystems using Alburnus alburnus (bleak) as a bioindicator species. Additional LoEs that were used in the
study are: component-based methods for the assessment of SumTU in water based on monitoring data of the
Serbian Environmental Protection Agency (SEPA), effect based methods employing in vitro genotoxicological
analyses of Joint Danube Survey 4 (JDS4) water extracts and field derived species inventories for the
assessment and indication of ecological status/potential based on SEPA and JDS4 data. The study was
conducted within the JDS4 campaign at nine sampling sites at the Tisa, Sava, Velika Morava and Danube rivers
in the Republic of Serbia. In the case of three sampling sites, the results were uniform, meaning that all four
LoEs pointed to pollution pressure. The differences in the LoEs outcomes for other sites indicated the
importance of multiple LoEs approach for proper identification of ecological impact. In the case of current
study we have identified comet and micronucleus assay to be appropriate for the genotoxicological assessment
in the in situ studies due to high sensitivity in discrimination of sites in relation to pollution intensity, while
RAPD analysis to be more suitable for controlled ex situ investigations.

AB  - The rhizosphere represents a center of complex and dynamic interactions between plants and microbes, resulting in various positive effects on plant growth and development. However, less is known about the effects of indole-3-acetic acid (IAA) on aquatic plants. In this study, we report the characterization of four Pseudomonas strains isolated from the rhizosphere of the common duckweed (Lemna minor) with IAA-degradation and -utilization ability. Our results confirm previous reports on the negative effect of IAA on aquatic plants, contrary to the effect on terrestrial plants. P. putida A3-104/5 demonstrated particularly beneficial traits, as it exhibited not only IAA-degrading and -producing activity but also a positive effect on the doubling time of duckweeds in the presence of IAA, positive chemotaxis in the presence of IAA, increased tolerance to oxidative stress in the presence of IAA and increased biofilm formation related to IAA. Similarly, P. gessardii C31-106/3 significantly shortened the doubling time of duckweeds in the presence of IAA, while having a neutral effect in the absence of IAA. These traits are important in the context of plant–bacteria interactions and highlight the role of IAA as a common metabolite in these interactions, especially in aquatic environments where plants are facing unique challenges compared to their terrestrial counterparts. We conclude that IAA-degrading and -producing strains presented in this study might regulate IAA effects on aquatic plants and confer evolutionary benefits under adverse conditions (e.g., under oxidative stress, excess of IAA or nutrient scarcity).

AB  - Environmental studies which aim to assess the ecological impact of chemical and other types of pollution should employ a complex weight-of-evidence approach with multiple lines of evidence (LoEs). This study focused on in situ genotoxicological methods such as the comet and micronucleus assays and randomly amplified polymorphic DNA analysis as one of the multiple LoEs (LoE3) on the fish species Alburnus alburnus (bleak) as a bioindicator. The study was carried out within the Joint Danube Survey 4 (JDS4) at nine sites in the Danube River Basin in the Republic of Serbia. Out of nine sampling sites, two were situated at the Tisa, Sava, and Velika Morava rivers, and three sites were at the Danube River. The three additionally employed LoEs were: SumTUwater calculated based on the monitoring data in the database of the Serbian Environmental Protection Agency (SEPA) (LoE1); in vitro analyses of JDS4 water extracts employing genotoxicological methods (LoE2); assessment of the ecological status/potential by SEPA and indication of the ecological status for the sites performed within the JDS4 (LoE4). The analyzed biomarker responses in the bleak were integrated into the unique integrated biomarker response index which was used to rank the sites. The highest pollution pressure was recorded at JDS4 39 and JDS4 36, while the lowest was at JDS4 35. The impact of pollution was confirmed at three sites, JDS4 33, 40, and 41, by all four LoEs. At other sampling sites, a difference was observed regarding the pollution depending on the employed LoEs. This indicates the importance of implementing a comprehensive weight-of-evidence approach to ensure the impact of pollution is not overlooked when using only one LoE as is often the case in environmental studies.

AB  - In recent years the randomly amplified polymorphic DNA method (RAPD) is frequently used in ecogenotoxicology. Within two case studies on the Sava River and the Danube River, muscle tissue of Alburnus alburnus (bleak) specimens sampled from nine sites was used for RAPD analysis. The RAPD results on the Sava River study indicate the grouping of specimens from polluted sites (UB and UK) as opposed to specimens from the less polluted site, SZ. The RAPD results of the Danube River case study do not show a clear bleak grouping in relation to pollution pressures, indicating that additional analyses are needed.
