Fluoride transport in Arabidopsis thaliana plants is impaired in Fluoride EXporter (FEX) mutants..

February 13, 2024

Introduction Fluoride (F–) is abundant in the environment, but is toxic to plant and animal life. Fluoride is naturally released into the biosphere by weathering of fluoride-containing minerals and from volcanoes and marine aerosols (Symonds et al. 1988; Weinstein and Davison 2004). Fluoride is released by coal burning and manufacturing processes involving metal smelting or […]

Widespread genetic switches and toxicity resistance proteins for fluoride

July 2, 2021

Abstract Most riboswitches are metabolite-binding RNA structures located in bacterial messenger RNAs where they control gene expression. We have discovered a riboswitch class in many bacterial and archaeal species whose members are selectively triggered by fluoride but reject other small anions, including chloride. These fluoride riboswitches activate expression of genes that encode putative fluoride transporters, […]
