This study was conducted to reveal the genetic diversity of soybean-nodulating rhizobia in Nepal in relation to climate and soil properties. A total of 102 bradyrhizobial strains were isolated from the root nodules of soybeans cultivated in 12 locations in Nepal varying in climate and soil properties, and their genetic diversity was examined based on 16S(More)
Reproductive success depends on a robust and appropriately timed preovulatory luteinizing hormone (LH) surge, which is induced by the activation of gonadotropin-releasing hormone (GnRH) neurons in response to positive feedback from increasing estrogen levels. Here we document an increase in postsynaptic GluR2-lacking Ca2+ -permeable AMPA-type glutamate(More)
Partially-puri®ed extracellular laccase of Coriolus versicolor transformed chlorophenols in the following order: 2,4,6-dichlorophenol and 4-chlorophenol, whereas ferulic and p-coumaric acids inhibited transformations of 2,4,6-trichlorophenol, 2,3-, 2,4-and 2,6-dichlorophenols and 2-chlorophenol. The three phenolic acids have similar chemical structures.(More)
Bradyrhizobium japonicum and Bradyrhizobium elkanii dominated soybean nodules in temperate and subtropical regions in Nepal, respectively, in our previous study. The aims of this study were to reveal the effects of temperature on the nodulation dominancy of B. japonicum and B. elkanii and to clarify the relationship between the effects of temperature and(More)
Synechococcus leopoliensis CCAP1405/1 cannot grow on common solid media; however, the strain can grow when co-cultured with Bacillus subtilis 168. Gene-disruptant strains of B. subtilis 168 by pMUTINs at the following sites lost the ability to support the growth of S. leopoliensis CCAP1405/1 on agar media: yxeO and yufO (transporter), yxdK (histidine(More)
This study was conducted to reveal the genetic diversity of common bean (Phaseolus vulgaris L.) nodulating rhizobia in various agroecological regions in Nepal. A total of 63 strains were isolated from common bean grown in the soils collected from seven bean fields in Nepal and characterized based on the partial sequences of 16S–23S internal transcribed(More)
