Background and purpose: Datura metel L. plant is a reach source of medicinal alkaloids including hiociamin, scopolamine and atropine. Ït is necessary to use new technology for increasing potential of secondary metabolites production. There are different methods for this approach. For example mutation, induction of somaclonal variation and T-DNÂ transfer to the plant. Materials and methods:...

Pinus densiflora is an important pine species in Northeast Asia due to its historical, cultural, and economic values. Pine wood nematode (PWN) seriously damages P. densiflora, causing the wilt disease (PWD). Changes of phyto-compounds resin monoterpenes after infection PWN were studied. The changes identified by GC-MS control infected densiflora. Among phytochemicals (in densiflora), 3-carene w...

The focus of the Children's Vaccine Initiative is to encourage the discovery of technology that will make vaccines more readily available to developing countries. Our strategy has been to genetically engineer plants so that they can be used as inexpensive alternatives to fermentation systems for production of subunit antigens. In this paper we report on the immunological response elicited in vi...

transgene integration and expression in host plant is quite unpredictable and is considered as the major problem in plant transformation. the variation in transgene copy number in transgenic plants influences the expression level and is one of such complication. in many plant species, the analysis of transgenic plants has shown that independent transgenic plants have one to many copies of trans...

Cytokinins are phytohormones that are involved in various regulatory processes throughout plant development, but they are also produced by pathogens and known to modulate plant immunity. A novel transgenic approach enabling autoregulated cytokinin synthesis in response to pathogen infection showed that cytokinins mediate enhanced resistance against the virulent hemibiotrophic pathogen Pseudomon...

Purine nucleotides are essential components to sustain plant growth and development. In plants they are either synthesized "de novo" during the process of purine biosynthesis or are recycled from purine bases and purine nucleosides throughout the salvage pathway. Comparison between animals, microorganisms and Arabidopsis, the first plant species with a completely sequenced genome, shows that pl...

The Nicotiana plumbaginifolia gnl gene encoding a 8-1,3-glucanase isoform has been characterired. The gnl product represents an isoform distinct from the previously identified tobacco 8-1,3-glucanases. By expressing gnl in Escherichia coli, we have determined directly that the encoded protein does, indeed, correspond to a &1,3glucanase. In N. plumbaginifolia, gnl was found to be expressed in ro...

While often thought of as a smoking drug, tobacco (Nicotiana spp.) is now considered as a plant of choice for molecular farming and biofuel production. Here, we describe a noninvasive means of deriving both the distribution of lipid and the microtopology of the submillimeter tobacco seed, founded on nuclear magnetic resonance (NMR) technology. Our platform enables counting of seeds inside the i...

In recent years, vaccination programs have advanced significantly due to the progress in molecular biology and biotechnology. Research on plant-made vaccines has become a very tempting subject and transgenic plant technology to produce human or animal vaccines has attracted much attention. Numerous advantages have been reported for vaccine production in transgenic plants such as low cost, ease ...
