Main conclusion This review highlights the most recent updated information available about
Zn phytotoxicity at physiological, biochemical and molecular levels, uptake mechanisms as …

Zinc (Zn) plays an important role in the physiology and biochemistry of plants due to its
established essentiality and toxicity for living beings at certain Zn concentration ie, deficient …

Plants are very often confronted by different heavy metal (HM) stressors that adversely
impair their growth and productivity. Among HMs, chromium (Cr) is one of the most prevalent …

Natural and human activities introduced an excess level of toxic lead (Pb) to the
environment. Pb has no known biological significance and its interactions with plants lead to …

We investigated the physiological and biochemical mechanisms by which H2S mitigates the
cadmium stress in rice. Results revealed that cadmium exposure resulted in growth …

Plants exposed to excess metals are challenged by an increased generation of reactive
oxygen species (ROS) such as superoxide (O 2•-), hydrogen peroxide (H2O2) and the …

In this study, we examined the possible mechanisms of trehalose (Tre) in improving copper-
stress (Cu-stress) tolerance in rice seedlings. Our findings indicated that pretreatment of rice …

Chromium is considered one of the most severe toxic elements affecting agriculture.
Soybean seedlings under chromium stress were treated with glutathione and buthionine …

Arsenic (As) being a toxic metalloid adversely affects plant growth and yield, as well as
poses severe risks to human health. Hydrogen sulfide (H 2 S) has emerged a vital signaling …

Hydrogen sulfide (H 2 S) is helpful for maintaining plant growth under abiotic stresses. The
current study elucidated the physiological and biochemical strategies by which sodium …
