Silver Nanoparticles for Enhancing the Efficiency of Micropropagation of Banana ( L.).

Silver nanoparticles (AgNPs) have numerous applications in plant biotechnology. The unique biological activities of AgNPs in reducing microbial contamination and promoting plant growth have encouraged their use in the development of novel culture systems for the cultivation of several plant species. In this study, the influence of (80 nm-100 nm) AgNPs on the micropropagation of banana was examined by incorporating AgNPs into shoot multiplication and rooting media at concentrations of 3 mg/L-15 mg/L.

Population mixing of Rhizobium leguminosarum bv. viciae nodulating Vicia faba: the role of recombination and lateral gene transfer.

The level and mechanisms of population mixing among faba bean (Vicia faba) rhizobia of different geographic origins (three ecoregions of China and several Western countries) were analysed by sequencing three chromosomal housekeeping loci (atpD, recA and glnII) and one nodulation gene (nodD). Eight distinct sublineages of Rhizobium leguminosarum bv. viciae (Rlv) were identified by concatenated sequences of chromosomal loci.
