Wildlife is subject to various sources of pollution, including ionizing radiation. Adverse effects can impact the survival, growth, or reproduction of organisms, later affecting population dynamics. In invertebrates, reproduction, which directly impa

Early studies have shown that cesium (Cs+) competes with the macronutrient potassium (K+) for uptake by plants. The present study investigates the effect of K+ supply on Cs+ uptake and translocation in Arabidopsis thaliana. Taking advantage of the fr
