background: transient and stable transformation of host plants are the common techniques to produce transgenic plants. however, the main drawback of stable transformation is the fact that it takes quite a long time to produce a transgenic line. while, transient gene expression is a quick method to produce recombinant proteins in plants.  objective: the main goal of the present study was to eval...

one of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific rna-dependent silencing pathway termed post-transcriptional gene silencing(ptgs). in this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. potato virusy (pvy) is one of the mostdamaging viruses of potato, infecting...

haploid microspore-derived embryos (mdes) of wheat were obtained by in vitro androgenesis. these  embryos were employed to evaluate the transient expression of gus gene (uida) following particle bombardment. using the bio-rad pds-1000/he system, the physical parameters including rupture disk pressure (900, 1100 and 1350 psi); microprojectile travel distance (6 and 9 cm); gold particles size (0....

conclusions by employment of gene optimization strategies, use of viral-based vectors and suppression of plant-derived gene silencing effect, efficient transient expression of hcvcp in tobacco with proper antigenic properties could be possible. background hepatitis c virus (hcv) is major cause of liver cirrhosis in humans. hcv capsid (core) protein (hcvcp) is a highly demanded antigen for vario...

background: transient gene expression (tge) gained popularity over the last decade as a rapid method for the production of milligram to gram quantities of recombinant proteins for preclinical studies in biophama industry. thereby, the optimization of the tge technique for chinese hamster ovary (cho) as the dominant host for the production of biotherapeutics is of great interest to reach the val...

Foot and Mouth Disease (FMD) is a very dangerous livestock disease which causes a serious loss in the production of milk and meat. Therefore, producing an effective recombinant subunit vaccine virus this disease is of great importance. Transient gene expression is a valuable tool to reach rapid and acceptable recombinant vaccine. An Agrobacterium-mediated transient gene expression assay was car...

Gene transfer to plants and the production of transgenic plants with various purposes, such as improving the performance and quality, resistance to pests, diseases, etc., and of great importance are carried out Gene transfer to plants performs to evaluate the transient and permanent gene expression. Transient expression is quick, easy and simple and is not influenced by position effect compare ...

Due to the nonlinear nature of the Bang-Bang phase-locked loops (BBPLLs), its transient analysis is very difficult. In this paper, new equations are proposed for expression of transient behavior of the second order BBPLLs to phase step input. This approach gives new insights into the transient behavior of BBPLLs. Approximating transient response to reasonable specific waveform the loop tran...
