摘要: Copper is an essential metal for normal plant growth and development, although it also potentially toxic. participates in numerous physiological processes cofactor many metalloproteins, however, problems arise when excess copper present cells. Excess inhibits impairs important cellular (i.e., photosynthetic electron transport). Since both a toxic element, involving complex network of trafficking pathways, different strategies have evolved plants to appropriately regulate its homeostasis as function the environmental level. Such must prevent accumulation freely reactive form (metal detoxification pathways) ensure proper delivery this element target metalloproteins. The mechanisms involved acquisition micronutrient not been clearly defined number genes recently identified which encode potential transporters. This review gives briefly overview current understanding more features concerning toxicity tolerance plants, brings information recent findings on including factors, transporters chaperones.
