We previously demonstrated that rice (Oryza sativa) SECRETORY CARRIER MEMBRANE PROTEIN1 (OsSCAMP1)-yellow fluorescent protein in transgenic tobacco (Nicotiana tabacum) Bright Yellow-2 cells locates to the plasma membrane and to motile punctate structures, which represent the trans-Golgi

Expression of wild rice Porteresia coarctata PcNHX1 antiporter gene (PcNHX1) in tobacco controlled by PcNHX1 promoter (PcNHX1p) confers Na+-specific hypocotyl elongation and stem-specific Na+ accumulation in transgenic tobacco.

Soil salinization is a major abiotic stress condition that affects about half of global agricultural lands. Salinity leads to osmotic shock, ionic imbalance and/or toxicity and build-up of reactive oxygen species. Na⁺/H⁺ antiporters (NHXs) are integral membrane transporters that catalyze the

We examined the function of the rice (Oryza sativa L.) antiporter-regulating protein OsARP by overexpressing it in tobacco (Nicotiana tabacum L.). In public databases, this protein was annotated as a putative Os02g0465900 protein of rice. The OsARP gene was introduced into tobacco under the control

Overexpression of phytochrome A results in an increased inhibition of hypocotyl elongation under red and far-red light. We used this approach to assay for the function of N-terminal mutations of rice (Oryza sativa L.) phytochrome A. Transgenic tobacco seedlings that express the wild-type rice

BACKGROUND Regulation of gene expression at the level of transcription is a major control point in many biological processes. Transcription factors (TFs) can activate and/or repress the transcriptional rate of target genes and vascular plant genomes devote approximately 7% of their coding capacity

A tobacco (Nicotiana tabaccum) calmodulin-binding protein kinase, NtCBK2, is regulated differentially by calmodulin isoforms.

A calcium (Ca2+)/calmodulin (CaM)-binding protein kinase (CBK) from tobacco (Nicotiana tabaccum ), NtCBK2, has been characterized molecularly and biochemically. NtCBK2 has all 11 conserved subdomains of the kinase-catalytic domain and a CaM-binding site as shown by other kinases, including

In plants, the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactodiacylglycerol (DGDG) are major constituents of photosynthetic membranes in chloroplasts. One of the key enzymes for the biosynthesis of these galactolipids is MGDG synthase (MGD). To investigate the role of MGD in the

Al(3+) toxicity in growing plants is considered as one of the major factors limiting the production of crops on acidic soils worldwide. In the last 15 years, it has been proposed that Al(3+) toxicity are mediated with distortion of the cellular signaling mechanisms such as calcium signaling

Arabidopsis thaliana At-4/1 is the protein of unknown function capable of polar localization in plant cells and intercellular trafficking. In this work, we cloned cDNAs and chromosomal genes of At-4/1 orthologues from several Nicotiana species. Similarly to the 4/1 genes of A. thaliana and Oryza

In rice (Oryza sativa L.), cytosolic triosephosphate isomerase (TPI) is encoded by a single gene. TPI catalyzes a vital step in glycolysis, and RNA blots showed that the tpi gene is expressed in all vegetative tissues (root, culm, and leaves) and in rice suspension cells. No effect of light on

Aldehyde dehydrogenases (ALDHs) play a central role in detoxification processes of aldehydes generated in plants when exposed to the stressed conditions. In order to identify genes required for the stresses responses in the grass crop Zea mays, an ALDH (ZmALDH22A1) gene was isolated and

Inositol is a cyclic polyol that is involved in various physiological processes, including signal transduction and stress adaptation in plants. l-myo-inositol monophosphatase (IMPase) is one of the metal-dependent phosphatase family members and catalyzes the last reaction step of biosynthesis of

Cell-penetrating peptides (CPPs) are used for various applications, especially in the biomedical field. Recently, CPPs have been used as a part of carrier to deliver proteins and/or genes into plant cells and tissues; hence, these peptides are attractive tools for plant biotechnological and

Transgenic tobacco ( Nicotiana tabacum L.) plants constitutively expressing a rice ( Oryza sativa L.) gene encoding a small GTPase, rgp1, showed marked resistance to tobacco mosaic virus (TMV) infection compared with the wild type [H. Sano et al. (1994) Proc Natl Acad Sci USA 91:10556-10560]. In

The 5'-untranslated region of the tobacco alcohol dehydrogenase gene functions as an effective translational enhancer in plant.

The alcohol dehydrogenase gene (NtADH) was previously isolated from tobacco BY2 suspension cultured cell. Expression of this gene was dramatically increased only during the early stationary phase, and the 5'-untranslated region (5'-UTR) was hypothesized to be involved in the stimulatory effect at
