Tandem Quadruplication of HMA4 in the Zinc (Zn) and Cadmium (Cd) Hyperaccumulator Noccaea caerulescens
Zinc (Zn) and cadmium (Cd) hyperaccumulation may have evolved twice in the Brassicaceae, in Arabidopsis halleri and in the Noccaea genus. Tandem gene duplication and deregulated expression of the Zn transporter, HMA4, has previously been linked to Zn/Cd hyperaccumulation in A. halleri. Here, we tested the hypothesis that tandem duplication and deregulation of HMA4 expression also occurs in Nocc...
متن کاملComparative transcriptome analysis of the metal hyperaccumulator Noccaea caerulescens
The metal hyperaccumulator Noccaea caerulescens is an established model to study the adaptation of plants to metalliferous soils. Various comparators have been used in these studies. The choice of suitable comparators is important and depends on the hypothesis to be tested and methods to be used. In high-throughput analyses such as microarray, N. caerulescens has been compared to non-tolerant, ...
متن کاملDe novo transcriptome assemblies of four accessions of the metal hyperaccumulator plant Noccaea caerulescens
Noccaea caerulescens of the Brassicaceae family has become the key model plant among the metal hyperaccumulator plants. Populations/accessions of N. caerulescens from geographic locations with different soil metal concentrations differ in their ability to hyperaccumulate and hypertolerate metals. Comparison of transcriptomes in several accessions provides candidates for detailed exploration of ...
متن کاملFunctional analysis of metal tolerance proteins isolated from Zn/Cd hyperaccumulating ecotype and non-hyperaccumulating ecotype of Sedum alfredii Hance.
The Zn/Cd hyperaccumulating ecotype (HE) of Sedum alfredii Hance can accumulate 24- and 28-fold higher leaf and stem Zn concentrations when compared with the non-hyperaccumulating ecotype (NHE) of Sedum. Heterologous expression of a metal tolerance protein (MTP1) encoding gene from HE plants (SaMTP1) or the homologous gene from NHE plants (SnMTP1) suppressed Zn(2+) hypersensitivity in the Δzrc1...
متن کاملTransport and detoxification of cadmium, copper and zinc in the Cd/Zn hyperaccumulator plant Thlaspi caerulescens
Hyperaccumulators store most of the accumulated metal in the vacuoles of large leaf epidermal cells (storage cells). For investigating cadmium uptake, we incubated a protoplast mixture obtained by digestion of leaves of Thlaspi caerulescens (Ganges ecotype) with a Cd-specific fluorescent dye. A fluorescence kinetic microscope was used for selectively measuring Cd-uptake and photosynthesis in di...
