Wheat is recalcitrant to genetic transformation. A potential solution is to manipulate the expression of some host proteins involved in T-DNA integration process. VirE2 interacting protein 2 (VIP2) plays an important role in T-DNA transport and integration. In this study, a TaVIP2 gene was cloned

Over-expression of a tobacco nitrate reductase gene in wheat (Triticum aestivum L.) increases seed protein content and weight without augmenting nitrogen supplying.

Heavy nitrogen (N) application to gain higher yield of wheat (Triticum aestivum L.) resulted in increased production cost and environment pollution. How to diminish the N supply without losing yield and/or quality remains a challenge. To meet the challenge, we integrated and expressed a tobacco

Silver nitrate effectively promoted shoot regeneration in wheat (Triticum aestivum L.) callus cultures derived from immature embryos. This effect could be observed in both weakly and strongly regenerating cultivars, and in using material from both field and greenhouse grown plants. The role of

Overexpression of a Triticum aestivum Calreticulin gene (TaCRT1) Improves Salinity Tolerance in Tobacco.

Calreticulin (CRT) is a highly conserved and abundant multifunctional protein that is encoded by a small gene family and is often associated with abiotic/biotic stress responses in plants. However, the roles played by this protein in salt stress responses in wheat (Triticum aestivum) remain obscure.

A wheat (Triticum aestivum) protein phosphatase 2A catalytic subunit gene provides enhanced drought tolerance in tobacco.

OBJECTIVE Multiple copies of genes encoding the catalytic subunit (c) of protein phosphatase 2A (PP2A) are commonly found in plants. For some of these genes, expression is up-regulated under water stress. The aim of this study was to investigate expression and characterization of TaPP2Ac-1 from

RETRACTION of: Overexpression of VP, a vacuolar H+-pyrophosphatase gene in wheat (Triticum aestivum L.), improves tobacco plant growth under Pi and N deprivation, high salinity, and drought.

Establishing crop cultivars with strong tolerance to P and N deprivation, high salinity, and drought is an effective way to improve crop yield and promote sustainable agriculture worldwide. A vacuolar H+-pyrophosphatase (V-H+-PPase) gene in wheat (TaVP) was functionally characterized in this study.

Differential expression of three BOR1 genes corresponding to different genomes in response to boron conditions in hexaploid wheat (Triticum aestivum L.).

Boron (B) is an essential micronutrient for plants. Efflux-type B transporters, BORs, have been identified in Arabidopsis thaliana and rice. Here we identified BOR1 genes encoding B efflux transporters, from the hexaploid genome of wheat (Triticum aestivum L.). We cloned three genes closely related

Characterization of three homoeologous cDNAs encoding chloroplast-targeted aminolevulinic acid dehydratase in common wheat.

In the tetrapyrrole biosynthetic pathway of higher plants, 5-aminolevulinic acid (ALA) is metabolized by ALA dehydratase (ALAD). Here, we isolated ALAD1 cDNA from common wheat (Triticum aestivum L.) and its diploid progenitors, and produced transgenic tobacco plants expressing the wheat ALAD1 gene.

The promoter of a pollen-specific gene TaPSG719 was isolated from wheat (Triticum aestivum L.) by inverse-PCR (IPCR). Sequence analysis revealed that the promoter contains two cis-acting elements (AGAAA and GTGA) known to confer anther/pollen-specific gene expression which suggests that the promoter

Influence of acetylcholine agonists and antagonists on the swelling of etiolated wheat (Triticum aestivum L.) mesophyll protoplasts.

Etiolated wheat (Triticum aestivum L.) mesophyll protoplasts swell within 30 min in darkness after a red light (R) pulse or addition of acetylcholine (ACh), if 0.5 mM CaCl2 is present in the medium. In addition, ACh is also able to induce swelling in the presence of both 0.1 mM KCl or NaCl. Besides

Increased freezing tolerance through up-regulation of downstream genes via the wheat CBF gene in transgenic tobacco.

The wheat (Triticum aestivum L.) CBF gene family is assumed to play important roles in development of low-temperature and freezing tolerance through activation of the downstream Cor/Lea genes. However, no direct evidence shows association of the wheat CBF genes with stress tolerance or any

Puroindolines are two small proteins so called for the presence of an hydrophobic tryptophan-rich domain. Associated to wheat starch granules in Triticum aestivum, puroindolines have been shown to be responsible for the softness of the wheat endosperm. Moreover, have been proved to possess

Analysis of the gene expression differentiation in leaves of wheat (Triticum aestivum L.) cultivar Baofeng 7228, under salt stress, was carried out by Differential-Display Reverse Transcription-polymerase Chain Reaction (DDRT-PCR.) Twenty-seven differential cDNA fragments were obtained. The

A wheat MYB transcriptional repressor TaMyb1D regulates phenylpropanoid metabolism and enhances tolerance to drought and oxidative stresses in transgenic tobacco plants.

MYB transcription factors are involved in the regulation of plant development and response to biotic and abiotic stress. In this study, TaMyb1D, a novel subgroup 4 gene of the R2R3-MYB subfamily, was cloned from wheat (Triticum aestivum L.). TaMyb1D was localized in the nucleus and functioned as a
