Abiotic stresses (such as metals/metalloids, salinity, ozone, UV-B radiation, extreme
temperatures, and drought) are among the most challenging threats to agricultural system …

Heavy metal (HM)-accumulating herbaceous and woody plants are employed for
phytoremediation. To develop improved strategies for enhancing phytoremediation …

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 …

Hydrogen sulfide (H 2 S) was initially recognized as a toxic gas and its biological functions
in mammalian cells have been gradually discovered during the past decades. In the latest …

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

Salicylic acid (SA) and gibberellins (GAs), as two important plant growth hormones, play a
key role in increasing plant tolerance to abiotic stress. They contribute to the increased plant …

Phytoextraction is an environmentally friendly and a cost-effective strategy for remediation of
heavy metal contaminated soils. However, lower bioavailability of some of the metals in …

Plant peroxisomes have the capacity to generate different reactive oxygen and nitrogen
species (ROS and RNS), such as H2O2, superoxide radical (O2·−), nitric oxide and …

Consistent use of large amounts of fertilizers, pesticides, and mulch can cause the
accumulation of harmful substances in cotton plants. Among these harmful substances …

The mining of heavy metals from the environment leads to an increase in soil pollution,
leading to the uptake of heavy metals into plant tissue. The build-up of toxic metals in plant …
