Lithium in environment and potential targets to reduce lithium toxicity in plants

Industrialization and inevitable mining have resulted in the release of some metals in environment, which have different uses on the one hand and also showed environmental toxicity. Lithium (Li) is one of them; however, its excess use in different fields or inappropriate disposal methods resulted in high Li accumulation in soil and groundwater. This subsequently is affecting our environment and more potentially our arable crop production system. In humans, Li has been extensively studied and causes numerous detrimental effects at different organ levels. Moreover, increases in Li in groundwater and food items, cases for mental disorders have been reported in different regions of the world. In plants, only a few studies have been reported about toxic effects of lithium in plants. Moreover, plant products (fruits, grains or other plant parts) could be a major source of Li toxicity in our food chain. Therefore, it is more imperative to understand how plants can be developed more tolerant to Li toxicity. In this short mini-review article, we primarily highlighted and speculated Li uptake, translocation and Li storage mechanism in plants. This article provides considerable information for breeders or environmentalist in identifying and developing Li hyperaccumulators plants and environment management.
