Rare earth elements activate endocytosis in plant cells.
It has long been observed that rare earth elements (REEs) regulate multiple facets of plant growth and development. However, the underlying mechanisms remain largely unclear. Here, using electron microscopic autoradiography, we show the life cycle of a light REE (lanthanum) and a heavy REE (terbium) in horseradish leaf cells. Our data indicate that REEs were first anchored on the plasma membran...
متن کاملGeochemistry of Rare Earth Element in garnet group minerals in some regional metamorphic complexes - Central Iran Micro-Continent (CIMC)
This study focuses on the amount and concentration of trace elements and REEs pattern in garnet crystals which experienced regional metamorphism in the central Iran micro-continent, including the areas of Deh-Salm, Zaman Abad, Mishdowan, and Tanbour. Generally, garnet crystals are isolated from mica schists of greenschist to amphibolite facies. Mineralogical composition of garnets shows almandi...
متن کاملRare-earth metal hydroxylamide complexes.
The rare-earth metal hydroxylamide compound Y[N(SiHMe2)2]2[ONBn2][THF] (1) was prepared by the silylamide elimination pathway from the reaction of N,N-dibenzylhydroxylamine, Bn2NOH (Bn = CH2C6H5), with Y[N(SiHMe2)2]3[THF]2 and was characterised by multinuclear NMR spectroscopy and elemental analysis. The compounds [Cp2Y(ONBn2)]2 (2a) [Cp2Sm(ONBn2)]2 (2b) were obtained by the reactions of MCp3 (...

متن کاملThe multiple roles of arabinogalactan proteins in plant development.
Arabinogalactan proteins (AGPs) are: (a) structurally complex macromolecules composed of a polypeptide, large branched glycan chains, and lipid?; (b) markers of xylem development in Arabidopsis primary root?; (c) abundant extracellular matrix components in tobacco styles?; (d) active in tip growth of lily pollen tubes?; (e) able to promote somatic embryogenesis in carrot cell cultures?; (f) inv...
