The Ammonium Transporter SpAMT1;2 Contributes to Nitrogen Utilisation and Cadmium Accumulation in the Hyperaccumulator Sedum Plumbizincicola.

Sedum plumbizincicola (Sp) is a cadmium (Cd) hyperaccumulator found specifically in abandoned ancient mines where N is regularly deficient while Cd presents in excess. How Sp got adapted to this unique habitat remains unknown. Here, we reported relative abundant presence of NH in mine areas for Sp, and the isolation and functional characterisation of a putative NH transporter gene AMT1;2, which is highly expressed in Sp roots and encodes a pH-dependent dual affinity ammonium uptake transporter.

Two-step strategy, growth mechanism and optical properties of plasmonic Ag-modified ZnO nanomaterials.

In this paper, plasma silver (Ag) modified zinc oxide (ZnO) (AZO) was used to form AZO nanomaterials (including AZO nanofilms (NFm), AZO nanowires (NWs) and AZO nanoflowers (NFw)) in a two-step-controlled manner to investigate the effect of compounding different contents of Ag on the linear optical aspects of ZnO materials. The growth mechanism of the AZO nanomaterials with different strategies is discussed. If Ag nanoparticles (NPs) grow on the ZnO NFm surface, they first grow with ZnO as the core and then self-core into islands, which are undoubtedly influenced by factors such as the growth mechanism of ZnO as well as Ag.

Assessment of the contribution of chiral odorants to aroma property of baked green teas using an efficient sequential stir bar sorptive extraction approach.

Chiral volatile compounds are known to be distributed in teas at various enantiomeric ratios. However, the performance of each enantiomer, including aroma characteristics, aroma intensities, and contribution to the overall flavor of tea, is still unclear. In this study, aroma characteristics and intensities of 38 volatile enantiomers in standards and baked green teas with chestnut-like aroma and clean aroma were evaluated by an efficient sequential headspace-stir bar sorptive extraction (seq-HS-SBSE) approach combined with the enantioselective gas chromatography-olfactometry/mass spectrometry (Es-GC-O/MS) technique.

Galactosylation of rhamnogalacturonan-II for cell wall pectin biosynthesis is critical for root apoplastic iron reallocation in Arabidopsis.

Apoplastic iron (Fe) in roots represents an essential Fe storage pool. Reallocation of apoplastic Fe is of great importance to plants experiencing Fe deprivation, but how this reallocation process is regulated remains elusive, likely because of the highly complex cell wall structure and the limited knowledge about cell wall biosynthesis and modulation. Here, we present genetic and biochemical evidence to demonstrate that the Cdi-mediated galactosylation of rhamnogalacturonan-II (RG-II) is required for apoplastic Fe reallocation.
