Mercury toxicity, molecular reaction and tolerance in plants: A review
Keywords:mercury, plant, nutrient uptake, water status, contamination, transformation, transportation, toxicology
Cumulating of mercury in plants increase to the phytotoxicity and impairs numerous metabolic processes, including nutrient uptake, water status, and photosynthesis. Contamination of mercury in soils has become a great concern because of its natural release and anthropogenic activities. This research understanding the speciation of mercury, transformation, and transportation and toxicology
tolerant regulation in plants, and minimization strategy, introducing the sources of mercury contamination in soils. Mercury (Hg) exists in different forms, ionic mercury (Hg+2) is the predominant form in soils and readily absorbed by plants. Uptake, transport, and localization of mercury (Hg+2) in plants that induce phytotoxicity and damage considerable metabolic processes. Mechanisms of
mercury-induced toxicology, molecular response and gene networks for regulating plant tolerance. Extremely advance has been made in profiling of transcriptome and more importantly, uncovering a group of small RNAs that potentially mediates plant tolerance to mercury (Hg+2). Recently discovered several signaling molecules such as nitric oxide and carbon monoxide have described as the regulators of plant tolerance to mercury (Hg+2). Major importance to understand the extent of the toxicity in plants and animals and the consequences from the ingestion of contaminated food. Mercury (Hg+2) is easily modified into several oxidation states, and it can be spread in many ecosystems. Due to the recurrence of mercury (Hg+2) pollution and due to the lack of knowledge about the effects of this heavy metal in plants. The aim of this research is to provide a comprehensive review of the literature regarding mercury
