Genotoxicity effects of Flusilazole on the somatic cells of Allium cepa.

The aim of this study was to evaluate the effects of the fungicide flusilazole on somatic cells of Allium cepa. For evaluation of cytogenetic effects, root meristem cells of A. cepa were treated with 10, 20, 30 and 45 ppm (EC50 concentration) for 24, 48 and 72 h.

The effect of aluminium-stress and exogenous spermidine on chlorophyll degradation, glutathione reductase activity and the photosystem II D1 protein gene (psbA) transcript level in lichen Xanthoria parietina.

In this study, the effects of short-term aluminium toxicity and the application of spermidine on the lichen Xanthoria parietina were investigated at the physiological and transcriptional levels. Our results suggest that aluminium stress leads to physiological processes in a dose-dependent manner through differences in lipid peroxidation rate, chlorophyll content and glutathione reductase (EC 1.6.
