Gln synthetase (GS) is the key enzyme of primary ammonia assimilation in nitrogen-fixing root nodules of legumes and actinorhizal (Frankia-nodulated) plants. In root nodules of Datisca glomerata (Datiscaceae), transcripts hybridizing to a conserved coding region of the abundant nodule isoform, DgGS1-1, are abundant in uninfected nodule cortical tissue, but expression was not detectable in the i...

Volcanic activity has damaged or destroyed at least 20,000 ha of indigenous vegetation in the North Island in the last 450 years. The primary and secondary successions initiated are discussed and considered in relation to some recently proposed models of succession. Most of the variation relates to the scale and intensity of disturbance, and the type and heterogeneity of the substrate emplaced....

Gastrointestinal infections are still a major concern in the developing countries. The aim of this research was to investigate antimicrobial effects of five herbs in Iranian traditional medicine on some of the pathogenic intestinal bacteria. Hydroalcoholic extracts of Amaranthus paniculatus L. (seeds), Cannabis sativa L. (fruits), Rhus coriaria L. (epicarps), Urtica dioica L. (leaves), and Zata...
