In boron-rich soils of Turkey, boron tolerant wheat (Triticum aestivum L.) and sensitive bean (Phaseolus vulgaris L.) are most widely cultivated crops. In this study they have been studied to elucidate the probable genotoxic effects of boron by using RAPD analysis. During the study, root and stem lengths have been measured and inhibitory rates (%) of root growth have been found to be significant, starting from 10 (13%) and 5 ppm (19%) for wheat and bean, respectively, which is in strong correlation with the root DNA alterations; RAPD variations starting from 100 ppm for wheat and 25 ppm for bean. The preliminary findings encourage the use of these tools in investigation of genotoxic effects of boron on wheat, bean and the other crops.

Double-strand breaks represent the most dangerous form of DNA damage, and in resting cells, these breaks are sealed via the non-homologous end joining (NHEJ) factor Ligase IV (LIG4). Excessive NHEJ may be genotoxic, necessitating multiple mechanisms to control NHEJ activity. However, a clear mechanism of transcriptional control for them has not yet been identified.

This study explored the distribution of macronutrients (Ca, Mg, Na, K) and lithogenic (Ba, Cr, Ni, Mn, Fe) and mining-related (As, Pb, Cd, Cu, Zn) toxic metalloids and metals (TMMs) in tomato (Solanum lycopersicum L.), and its effects on plant development, productivity, genotoxicity, and human health, using a soil affected by mine tailings (AS) and an unaffected control soil (CS). The chemistry of soils reflected their mineralogy, and Fe-Ti oxides, sulfides and sulfosalts were found to be the most significant reservoirs of TMMs.

Monitoring of genotoxic chemicals released into the water cycle or formed through transformation processes is critical to prevent harm to human health. The development of the high-performance thin-layer chromatography (HPTLC)-umu bioassay combines sample separation and detection of genotoxic substances in the low ng/L concentration range. In this study, raw, process, and drinking water samples from 11 different waterworks in Germany were analyzed using the HPTLC-umu.

Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.
