Metal Hyperaccumulation Armors Plants against Disease
Metal hyperaccumulation, in which plants store exceptional concentrations of metals in their shoots, is an unusual trait whose evolutionary and ecological significance has prompted extensive debate. Hyperaccumulator plants are usually found on metalliferous soils, and it has been proposed that hyperaccumulation provides a defense against herbivores and pathogens, an idea termed the 'elemental d...
متن کاملMolecular mechanisms of metal hyperaccumulation in plants.
Metal hyperaccumulator plants accumulate and detoxify extraordinarily high concentrations of metal ions in their shoots. Metal hyperaccumulation is a fascinating phenomenon, which has interested scientists for over a century. Hyperaccumulators constitute an exceptional biological material for understanding mechanisms regulating plant metal homeostasis as well as plant adaptation to extreme meta...
متن کاملThe Genetic Basis of Metal Hyperaccumulation in Plants
A relatively small yet diverse group of plants are capable of sequestering metals in their shoot tissues at remarkably high concentrations that would be toxic to most organisms. This process, known as metal hyperaccumulation, is of interest for several reasons, including its relevance to the phytoremediation of metalpolluted soils. Most research on hyperaccumulators has focused on the physiolog...
متن کاملTrade-offs between pathogen and herbivore resistance.
During the past year genetic and pharmacological experiments have revealed a molecular basis for the cross-talk between signaling pathways mediating pathogen and herbivore resistance. These findings provide considerable insight into the apparently contradictory results reported for trade-offs between pathogen and herbivore resistance.
متن کاملThe current status of the elemental defense hypothesis in relation to pathogens
Metal hyperaccumulating plants are able to accumulate exceptionally high concentrations of metals, such as zinc, nickel, or cadmium, in their aerial tissues. These metals reach concentrations that would be toxic to most other plant species. This trait has evolved multiple times independently in the plant kingdom. Recent studies have provided new insight into the ecological and evolutionary sign...
