Plant growth regulators, especially those applied directly to the root system, are thought to significantly reduce growth of the root systems. Various perennials were treated with uniconazole (Concise, Fine Americas, Inc.) to evaluate effects on plant height as well as shoot and root dry weights. Plant height of Lobelia cardinalis was not affected by a 1 ppm uniconazole liner dip, but shoot dry...
Tuberculosis is one of the leading infectious diseases. In this work, a new genotyping method of Mycobacterium tuberculosis (Mtb) complex strain is presented. 27 Mtb genomes were analyzed for the presence of length polymorphism within polymorphic GC-rich gene sequences. Four genes, Rv3345c, Rv3507, Rv0747 and Rv3511, showing variation in length depending on the Mtb strain were selected for desi...
It is known that most chemicals, which have been increasingly used since ancient times, carcinogenic and mutagenic effects. As an alternative to these natural compounds, such as plant growth regulators (PGRs) used. However, are the PGRs obtain efficient plants in agriculture harmless it thought today when essential access foods food sectors? Therefore, this study investigates activity of two (K...
The Mycobacterium tuberculosis strains H37Rv and H37Ra are the most commonly used controls for M. tuberculosis identification in the clinical and research laboratory setting. To reduce the likelihood of misidentification and possible cross-contamination with this laboratory neotype, it is important to be able to distinguish H37 from clinical isolates. To provide a reference for identifying H37,...
An alternative in vitro protocol for embryo induction directly from intact living seedlings of Phalaenopsis aphrodite subspecies formosana was established in this study. Without the supplementation of plant growth regulators (PGRs), no embryos were obtained from all the seedlings when cultured on the solid medium. In contrast, embryos formed from the seedlings on the 2-layer medium and the 2-st...
Frog egg-like bodies (FELBs), novel somatic embryogenesis (SE) structures first observed in Solanum nigrum, were induced in Rorippa indica. NaCl-mediated salt and mannitol-mimicked drought stresses induced FELBs in R. indica, which is very different from the induction by plant growth regulators (PGRs) under low light condition that was used in S. nigrum FELB induction. It demonstrated that NaCl...
Human tuberculosis caused by Mycobacterium tuberculosis (Mtb) remains a significant disease in many countries. According to Iran's borders with Afghanistan and Pakistan, which are among the 22 high burden countries around the world, this study was conducted to analyze the current molecular epidemiology of tuberculosis and survey genetic diversity of Mtb strains in Markazi Province in center of ...
Sequencing of the entire genome of Mycobacterium tuberculosis identified a novel multigene family composed of two closely related subfamilies designated PE and PE_PGRS. The major difference between these two families is the presence of a domain containing numerous Gly-Ala repeats extending to the C terminus of the PE_PGRS genes. We have used a representative PE_PGRS gene from M. tuberculosis, R...
The need for effective nutrient management is crucial optimizing wheat production and increasing the plant’s ability to tolerate different environmental stresses. In this study, we assessed influence of new-generation PGRs foliar topdressing nitrogen fertilizer their interactive effects on yield quality parameters grain flour. A three-year field experiment was conducted dark chestnut soil Rosto...
