Relationship of non-protein thiol pools and accumulated Cd or Hg in the marine macrophyte Posidonia oceanica (L.) Delile

Anthocyanins, thiols, and antioxidant scavenging enzymes are involved in Lemna gibba tolerance to arsenic

“…The increase in nonprotein thiols content might indicate the induction of the synthesis of glutathione and metal-binding peptides, such as phytochelatins, which have important roles in the sequestration and homeostasis of different metals (Maserti et al 2005). In fact, the main strategy for As detoxification in plant cells is based on chelation by phytochelatins or other nonprotein thiols and the subsequent compartmentalization of the As-phytochelatin complex (Mishra et al 2008).…”

Kandelia obovata (S., L.) Yong tolerance mechanisms to Cadmium: Subcellular distribution, chemical forms and thiol pools

“…Researches have shown that GSH content in maize increased significantly under Cu exposure, but declined to a certain degree in the leaves and roots of tomato under Cd exposure (De Vos et al, 1992). The increase of GSH under heavy metal exposure may be due to that heavy metals stimulate GSH biosynthesis gene transcription, and stimulate the synthesis of c-glutamyl cysteine synthetase phthalate, glutathione synthetase, glutathione reductase and other enzymes (Maserti et al, 2005). Chen and Goldsbrough, 1994 considered that there were double effects of heavy metals stress: on the one hand, GSH synthesis increased under heavy metal stress; on the other hand, GSH was consumed with the synthesis of PCs.…”

Nonnutrient anthropogenic chemicals in seagrass ecosystems: Fate and effects

“…Furthermore, plant adaptation and recovery due to toxicant detoxification (e.g., metal binding) also needs consideration when extrapolating lab to field toxicity results. These processes have been reported for several chemicals and aquatic flora including seagrasses [36,101,[129][130][131][132][133][134].…”
