Selenium accumulation protects Brassica juncea from invertebrate herbivory and fungal infection.
TLDR
Se was shown to protect Indian mustard plants from fungal infection and from herbivory by caterpillars, but not by snails. Expand
Characterization of rhizosphere fungi from selenium hyperaccumulator and nonhyperaccumulator plants along the eastern Rocky Mountain Front Range.
TLDR
Even though Se is a commonly used antifungal agent, these results suggest that rhizosphere fungi from seleniferous habitats have widespread Se tolerance, likely an adaptive advantage in their Se-rich habitat. Expand
Selenium accumulation protects plants from herbivory by Orthoptera via toxicity and deterrence.
TLDR
It is demonstrated that both inorganic and organic forms of selenium protect plants from herbivory, and methylselenocysteine protected S. pinnata from invertebrate Herbivory and increased its long-term survival rate over an entire growth season. Expand
Overexpression of ATP sulfurylase in Indian mustard: effects on tolerance and accumulation of twelve metals.
TLDR
Overexpression of ATP sulfurylase may be a promising approach to create plants with enhanced phytoextraction capacity for mixtures of metals, both oxyanions and cations. Expand
Selenium protects plants from phloem-feeding aphids due to both deterrence and toxicity.
TLDR
Se can protect plants from feeding by aphids at leaf levels two orders of magnitude lower than those found in hyperaccumulators in the field, shed light on the possible functional significance of Se hyperaccUMulation. Expand
Selenium Distribution and Speciation in the Hyperaccumulator Astragalus bisulcatus and Associated Ecological Partners1[W][OA]
TLDR
In conclusion, hyperaccumulators live in association with a variety of Se-resistant ecological partners, and among these partners, microbial endosymbionts may affect Se speciation in hyper Accumulators. Expand
Overexpression of Enzymes Involved in Glutathione Synthesis Enhances Tolerance to Organic Pollutants in Brassica juncea
TLDR
The results suggest that GSH biosynthesis is limiting for atrazine detoxification in Indian mustard and that overexpression of enzymes involved in GSF biosynthesis offers a promising approach to create plants with the enhanced capacity to tolerate not only heavy metals, but also certain organics. Expand
Selenium hyperaccumulation offers protection from cell disruptor herbivores
TLDR
The finding that Se protected the two hyperaccumulator species from both cell disruptors lends further support to the elemental defense hypothesis and increases the number of herbivores and feeding modes against which Se has shown a protective effect. Expand
Influence of microbial associations on selenium localization and speciation in roots of Astragalus and Stanleya hyperaccumulators
TLDR
X-ray absorption spectromicroscopy was used to characterize the chemical composition and spatial distribu- tion of Se in roots of Astragalus and Stanleya hyperaccumulators, and Selenium was present throughout the roots, with the highest levels in the cortex. Expand
Expression of a mouse selenocysteine lyase in Brassica juncea chloroplasts affects selenium tolerance and accumulation
TLDR
Surprisingly, the selenium tolerance of the transgenic cpSL plants was reduced, perhaps due to interference of produced elemental seenium with chloroplastic sulphur metabolism. Expand
