Making targeted subsidies and the process of releasing energy market and specified criteria for the quality of energy delivered to consumers shows the necessity for the explanation of energy production in Iran. In the meantime, thermal power plants produce about 85% of electricity in Iran. Steam and gas turbine power plants have created the vast capacity of power generation in thermal plants, b...

the purpose of this study was to analyze biotechnology experts’ attitude in university centers of tehran province towards use of transgenic plants. the design of the study was descriptive, and it was carried out through a survey method. the target population consisted of biotechnology experts in university centers of tehran province (n=75). though kerjcie and morgan sample size table and ratio ...

context functional dyspepsia (fd) is a functional gastro-intestinal disorder with high prevalence. among various treatment options, treatment by complementary and alternative medicines especially herbal remedies also practiced. traditional iranian medicine (tim), a valuable resource of valid applied studies of ancient iranian scholars, recommends numerous medicinal plants to treat dyspepsia sym...

Associational susceptibility has been predicted to arise when a target plant’s neighbor is more palatable to an herbivore than the target plant itself, resulting in attraction and spillover of the herbivore onto the target plant. This prediction was tested on two hosts of the invasive pyralid moth Cactoblastis cactorum Berg. A combination of observational surveys and experimental plantings were...

Plant microRNAs (miRNA) guide cleavage of target mRNAs by DICER-like proteins, thereby reducing mRNA abundance. Native precursor miRNAs can be redesigned to target RNAs of interest, and one application of such artificial microRNA (amiRNA) technology is to generate plants resistant to pathogenic viruses. Transgenic Arabidopsis plants expressing amiRNAs designed to target the genome of two unrela...

MicroRNAs (miRNAs) are small, non-coding RNAs that play vital roles in plant growth, development, and stress response. Increasing numbers of studies aimed at discovering miRNAs and analyzing their functions in plants are being reported. In this study, we investigated the effect of drought stress on the expression of miRNAs and their targets in plants of a diploid and derived autotetraploid Paul...

BACKGROUND Entomophilous non-native plants can directly affect the pollination and reproductive success of native plant species and also indirectly, by altering the composition and abundance of floral resources in the invaded community. Separating direct from indirect effects is critical for understanding the mechanisms underlying the impacts of non-native species on recipient communities. OB...

In recent years, metabolism researches using nanomaterials have been focusing on human and animal cells, and therefore very limited data are available about influence of nanomaterials on biosynthesis of secondary metabolites in plant cells. Plants produce different types of secondary metabolites including terpenoids, phenolics, tannins, and alkaloids, which are known to act as vital mediators f...

Potyviruses are the most important viral pathogens of crops worldwide. Under a contract with Gene Shears Pty Limited, we are using ribozyme genes to protect melon plants against two potyviruses: WMV2 and ZYMV. Different polyribozyme genes were designed, built and introduced into melons plants. Transgenic melon plants containing a resistance gene were obtained and their progeny was challenged by...
