Genetic material always remains at the risk of spontaneous or induced damage which challenges the normal functioning of DNA molecule, thus, DNA repair is vital to protect the organisms against genetic damage. Helicases, the unique molecular motors, are emerged as prospective molecules to engineer
Rice choline monooxygenase (OsCMO) protein functions in enhancing glycine betaine biosynthesis in transgenic tobacco but does not accumulate in rice (Oryza sativa L. ssp. japonica).

Glycine betaine (GB) is a compatible quaternary amine that enables plants to tolerate abiotic stresses, including salt, drought and cold. In plants, GB is synthesized through two-step of successive oxidations from choline, catalyzed by choline monooxygenase (CMO) and betaine aldehyde dehydrogenase

The cellular localization and molecular interactions are indicative of functions of a protein. The development of a simple and efficient method for subcellular localization of a protein is indispensable to elucidate gene function in plants. In this study, we assessed the feasibility of

Rice exhibits the greatest aluminum (Al) tolerance compared with other cereals such as wheat, barley, maize, etc. A full-length gene, OsCS1, encoding citrate synthase, which is highly induced by aluminum toxicity in rice (Oryza sativa L.), was isolated. Sequence analysis and the sub-cellular

MYB transcription factors are involved in many biological processes, including metabolism, stress response and plant development. In our previous work, ZmMYB59 was down-regulated by deep sowing during maize seed germination. However, there are few reports on seed germination regulated by MYB

Defensins are a group of plant antimicrobial peptides. In a previous study, it was reported that two recombinant rice (Oryza sativa L.) defensin (OsDEF) genes (OsDEF7 and OsDEF8) produced heterologously by bacteria inhibited the growth of several phytopathogen. Here, we analyzed gene expression

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
Overexpression of a new rice vacuolar antiporter regulating protein OsARP improves salt tolerance in tobacco.

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 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
