Sedum alfredii Hance (S. alfredii) is a native hyperaccumulator plant species in China that has strong tolerance and accumulation ability for Zn Cd. In addition, it good material the phytoextraction of soil heavy metal pollutants. However, specific effect high concentrations on growth S. its metabolic mechanisms are not clear. Using an untargeted metabolomics method, we analysed differential me...

The hyperaccumulating ecotype of Sedum alfredii Hance is a cadmium (Cd)/zinc/lead co-hyperaccumulating species of Crassulaceae. It is a promising phytoremediation candidate accumulating substantial heavy metal ions without obvious signs of poisoning. However, few studies have focused on the regulatory roles of miRNAs and their targets in the hyperaccumulating ecotype of S. alfredii. Here, we co...

The aim of this study was to investigate the effects of metal mobilizing plant-growth beneficial bacterium Phyllobacterium myrsinacearum RC6b on plant growth and Cd, Zn and Pb uptake by Sedum plumbizincicola under laboratory conditions. Among a collection of metal-resistant bacteria, P. myrsinacearum RC6b was specifically chosen as a most favorable metal mobilizer based on its capability of mob...

Dolgozatunkban a Kisalföld határainkon belülre eső területén 2015-2020 közötti időszakban végzett florisztikai kutatások legfontosabb eredményeit ismertetjük. Az előfordulási adatok felsorolását követően értékelésre kerül országos vagy regionális jelentőségük, növényföldrajzi, természetvédelmi szerepük. A felsorolásban 52 fajról szerepelnek új adatok, amelyek közül 40 hazánkban természetes (hon...

Evapotranspiration (ET) is a key moisture flux in both the urban stormwater management and energy budgets. While there are established methods for estimating ET agricultural crops, relatively little known about rates associated with plants Green Infrastructure settings. The aim of this study was to evaluate feasibility using porometry estimate rates. Porometry provides an instantaneous measurem...

Metallothioneins are cysteine-rich metal-binding proteins. In the present study, SaMT2, a type 2 metallothionein gene, was isolated from Cd/Zn co-hyperaccumulator Sedum alfredii Hance. SaMT2 encodes a putative peptide of 79 amino acid residues including two cysteine-rich domains. The transcript level of SaMT2 was higher in shoots than in roots of S. alfredii, and was significantly induced by Cd...
