Tolerance of plants to heavy metals could be in three ways: pumping out of heavy metals at the plasma membrane, through chelating of heavy metals and bounding the heavy metals to various thiol compounds in the cytosol and sequestering them into vacuoles. As a second line of defense, other mechanisms for detoxification of these metals are introduced that chelates, transports, sequesters and detoxifies these metal ions in the plant’s vacuole. The most sensitive plant species are enlisted and discussed in this review. In this review, a synopsis is presented about how plants, especially macrophytes, respond to heavy metal stress and we propose potential roles that phytohormones can play in the alleviation of metal toxicity in the aquatic environment. These mechanisms also focus on prevention of plants exposure to heavy metals present in the soil or providing tolerance to the plant by detoxifying the metals.

These mechanisms also focus on prevention of plants exposure to heavy metals present in the soil or providing tolerance to the plant by detoxifying the metals. HMs at toxic levels have the capability to interact with several vital cellular biomolecules such as nuclear proteins and DNA, leading to excessive augmentation of reactive oxygen species (ROS). Together, these findings demonstrate that under heavy metal stress conditions, plants show a rapid increase in ethylene production and reduced plant growth and development, indicating a strong involvement of this phytohormone in plant response to heavy metal toxicity (Maksymiec, 2007; Schellingen et al., 2014). https://doi.org/10.1111/pce.12706, Shi Q, Ding F, Wang X, Wei M (2007) Exogenous nitric oxide protect cucumber roots against oxidative stress induced by salt stress. Because of their high reactivity they can directly influence growth, senescence and energy synthesis processes. Plants have different mechanisms to fight stress, and they are responsible to maintain homeostasis of essential metals required by plants. It is focused on the entry of HMs into plants, its transport and accumulation, effects on the main physiological processes, gene expressions included in plant adaptive and defense responses during HM stress.
