Synthesized Allotetraploid F₂ Individuals obtained from the Cross <i>Aegilops speltoides</i>×<i>Ae. umbellulata</i>. (A Preliminary Note)

Gene loss, silencing and activation in a newly synthesized wheat allotetraploid.

We analyzed the events that affect gene structure and expression in the early stages of allopolyploidy in wheat. The transcriptome response was studied by analyzing 3072 transcripts in the first generation of a synthetic allotetraploid (genome S(l)S(l)A(m)A(m)), which resembles tetraploid wheat (genome BBAA), and in its two diploid progenitors Aegilops sharonensis (S(l)S(l)) and Triticum monoco...

Antimicrobial and Antioxidant Activity of the Biologically Synthesized Tellurium Nanorods; A Preliminary In vitro Study

Background: Recent theranostic (therapeutic or diagnostic) applications of tellurium nanoparticles have attracted a great interest for development of different methods for synthesis of this valuable nanostructure, especially via biological resources. Objectives: In the present study, the antimicrobial and antioxidant effects of the tellurium nanorods (Te NRs) biosynthesized by a bacterial...

Financial Burden of Border Hospital in Caring for Cross-Border Patients: A Short Note From Thailand

Nanofiltration Membranes Synthesized from Polyethyleneimine for Removal of MgSO4 from Aqueous Solution (RESEARCH NOTE)

A novel work was performed for fabrication and modification of composite nanofiltration (NF) membrane by polymerization reaction between polyethyleneimine (PEI) and triphthaloyldechloride (TPC). the main purpose of this work was water treatment. polysulfone was applied as a main polymer of substrate. The result of reaction between PEI and TPC would be formation of polyamide layer on the membran...

Organ-specific silencing of duplicated genes in a newly synthesized cotton allotetraploid.

Most eukaryotes have undergone genome doubling at least once during their evolutionary history. Hybridization followed by genome doubling (allopolyploidization) is a prominent mode of speciation in plants, leading to phenotypic novelty and changes in genome structure and gene expression. Molecular events that take place immediately after polyploid formation can be studied using newly synthesize...
