Marker-free transgenic white poplar (Populus alba L., cv ‘Villafranca’) plants, expressing the PsMT A1 gene from Pisum sativum for a metallothionein-like protein, were produced by Agrobacterium tumefaciens-mediated transformation. The 35SCaMV-PsMT A1 -NosT cassette was inserted into the ipt-type vector pMAT22. The occurrence of the abnormal ipt-shooty(More)
Rhodococcus opacus R7 is a naphthalene-degrading microorganism which is also able to grow on o-xylene. This work describes the isolation and analysis of two new genomic regions in which genes involved in naphthalene (nar gene cluster) and salicylate (gen gene cluster) degradation are located. In the nar gene cluster we found: two genes encoding the large(More)
We have previously reported that stabilization of the G-quadruplex structures in the HIV-1 long terminal repeat (LTR) promoter suppresses viral transcription. Here we sought to develop new G-quadruplex ligands to be exploited as antiviral compounds by enhancing binding toward the viral G-quadruplex structures. We synthesized naphthalene diimide derivatives(More)
BACKGROUND Fluorescent sensing of G-quadruplex nucleic acids (G4s) is an effective strategy to elucidate their role in vitro and in vivo. Small molecule ligands have often been exploited, producing an emission light up upon binding. Naphthalene diimides (NDIs), although potent G4 binders exhibiting red-NIR fluorophores, have only been marginally exploited,(More)
