A highly potential Zn biofortification tool: MTP1 in Triticum aestivum.

TaMTPs belong to metal tolerance proteins (MTPs) family in common wheat and have significant potential to address the "hidden hunger" caused by inadequate dietary intake of a key micronutrient (Zn). In this study, a total of 33 MTP members in Triticum aestivum were identified, among which six TaMTP1-likes were closely related to Arabidopsis thaliana MTP1 and were designated as TaMTP1-A/B/D and TaMTP1.1-A/B/D.

Genome-wide analysis of the MADS-box gene family of sea buckthorn () and their potential role in floral organ development.

Sea buckthorn ( ssp. ) is a deciduous shrub or small tree in the Elaeagnaceae family. It is dioecious, featuring distinct structures in female and male flowers.

MTP8 from Is Primarily Responsible for Manganese Tolerance.

Mineral nutrients, such as manganese (Mn) and iron (Fe), play essential roles in many biological processes in plants but their over-enrichment is harmful for the metabolism. Metal tolerance proteins (MTPs) are involved in cellular Mn and Fe homeostasis. However, the transporter responsible for the transport of Mn in wheat is unknown.

Characterization of the gene family encoding metal tolerance proteins in Triticum urartu: Phylogenetic, transcriptional, and functional analyses.

Homeostasis of microelements in organisms is vital for normal metabolism. In plants, the cation diffusion facilitator (CDF) protein family, also known as metal tolerance proteins (MTPs), play critical roles in maintaining trace metal homeostasis. However, little is known about these proteins in wheat.

New Biofortification Tool: Wheat TaCNR5 Enhances Zinc and Manganese Tolerance and Increases Zinc and Manganese Accumulation in Rice Grains.

Heavy metal contaminants and nutrient deficiencies in soil negatively affect crop growth and human health. The plant cadmium resistance (PCR) protein transports heavy metals. The abundance of PCR is correlated with that of cell number regulator (CNR) protein, and the two proteins have similar conserved domains.

Co-expression of multiple heavy metal transporters changes the translocation, accumulation, and potential oxidative stress of Cd and Zn in rice (Oryza sativa).

The OsHMA2, OsLCT1 and OsZIP3 transporters were all involved in zinc (Zn) and cadmium (Cd) transport. So far, only a few researches studied on the co-regulation effect of three transporters related to Zn and Cd transport. The present study showed that rice co-expressing OsLCT1-OsHMA2-OsZIP3 (LHZ) had longer roots and shoots than wild-type (WT) rice after Zn and Cd treatments.

Effects of cadmium toxicity on diploid wheat (Triticum urartu) and the molecular mechanism of the cadmium response.

Cadmium (Cd) is a widespread soil contaminant that readily accumulates in wheat, and posing a potential threat to human health. Our aim is to investigate Cd toxicity effect and molecular mechanisms for wheat. In this study, the physiological indexes, morphology, and gene expression patterns of diploid wheat (Triticum urartu) seedlings were evaluated after 2 and 5 d of a Cd treatment (10 μM CdSO).

Heterologous expression of TuCAX1a and TuCAX1b enhances Ca and Zn translocation in Arabidopsis.

TuCAX1a and TuCAX1b improved Ca and Zn translocation and TuCAX1b enhanced Ca, Zn, Mn and Fe content when exposed to Cd; Cd translocation was inhibited under Ca and Zn. Cation/H antiporters (CAXs) are involved in the translocation of Ca and various metal ions in higher plants. In the present study, TuCAX1a and TuCAX1b, two cation/H antiporters, were isolated from the diploid wheat Triticum urartu, and their metal cation translocation functions investigated.

Improved Cd, Zn and Mn tolerance and reduced Cd accumulation in grains with wheat-based cell number regulator TaCNR2.

Soil microelement deficiency and heavy metal contamination affects plant growth and development, but improving trace element uptake and reducing heavy metal accumulation by genetic breeding can help alleviate this. Cell number regulator 2 (TaCNR2) from common wheat (Triticum aestivum) are similar to plant cadmium resistance proteins, involved with regulating heavy metal translocation. Our aim was to understand the effect of TaCNR2 on heavy metal tolerance and translocation.

Triticum urartu MTP1: its ability to maintain Zn and Co homeostasis and metal selectivity determinants.

TuMTP1 maintains Zn and Co homeostasis by sequestering excess Zn and Co into vacuoles. The mutations NSEDD/VTVTT in the His-rich loop and I119F in TMD3 of TuMTP1 restrict metal selectivity. Mineral nutrients, such as zinc (Zn) and cobalt (Co), are essential or beneficial for plants but can be toxic at elevated levels.

Applying DNA Barcodes to Identify Closely Related Species of Ferns: A Case Study of the Chinese Adiantum (Pteridaceae).

DNA barcoding is a fast-developing technique to identify species by using short and standard DNA sequences. Universal selection of DNA barcodes in ferns remains unresolved. In this study, five plastid regions (rbcL, matK, trnH-psbA, trnL-F and rps4-trnS) and eight nuclear regions (ITS, pgiC, gapC, LEAFY, ITS2, IBR3_2, DET1, and SQD1_1) were screened and evaluated in the fern genus Adiantum from China and neighboring areas.
