Transfer RNAs (tRNAs) are central players in the protein translation machinery and as such are prominent targets for a large number of natural and synthetic antibiotics. This review focuses on the role of tRNAs in bacterial antibiosis. We will discuss examples of antibiotics that target multiple stages in tRNA biology from tRNA biogenesis and modification, mature tRNAs, aminoacylation of tRNA a...

Magnetic nanoparticle Fe304 have super paramagnetic, biological cell compatibility, low toxicity, antibiosis and bacteriostasis, drug loading, sustained release thermal effect. Using magnetic nanoparticies as source, masoporous glass two-dimensional bone framework was synthesized under the action of external field, which provides growth space for repair, proliferation metabolism, contribute to ...

the mustard aphid, lipaphis erysimi kalt, is one of the most severe pests of brassica species in iran and other tropical regions in the world. seven cultivars of three brassica species including b. napus (cv. licord, elite, okapi, hyola 401, and rgs003), b. juncea (cv. land race) and b. rapa (cv. park land) were evaluated to study the antixenosis and antibiosis resistance to l. erysimi under gr...

This study examines some of the potential mechanisms of resistance in selected Pieris (Ericaceae) taxa to the Andromeda lace bug, Stephanitis takeyai Drake and Maa, based on differences in resistance to lace bug feeding, and the possible role of leaf parameters such as leaf wax, toughness, nutrient composition, and stomatal characters in plant resistance. Experiments with extracts of leaf-surf...

The widespread cultivation of highly productive varieties agricultural crops often leads to the emergence and spread new intraspecific forms insects capable mass reproduction. control these processes is environmental importance possible based on monitoring variability phenol appearance pest populations. There has been carried out a vegetative field estimation phenogenetic such grain as bird che...

The aim of the current study was to evaluate antibacterial activity Chlorella vulgaris extracts against Stenotrophomonas maltophilia CSK1 isolated from a diseased cucumber fruit. To this end, water, methanol and ethanol were used separately as solvents extract active compounds dried vulgaris. S. identified using 16S rRNA gene sequencing at 99.93% identity level. bacterial strain confirmed by ph...
