The Rhizobium meliloti nifA product (NifA) shares extensive homology in its central region and at its C-terminal end with Rhizobium leguminosarum DctD and with NtrC from several species. All three proteins are transcriptional activators of NtrA (RpoN)-RNA polymerase-dependent promoters. Several large deletions of R. meliloti NifA were constructed to investigate the role of the conserved and div...

A Spatio-temporal data model for biodiversity is growing importance to the biodiversity data management, forest and environment control. Spatio-temporal data models have received much attention in the database research community because of their practical importance and interesting challenges they pose. This paper is discussed upon the research activities of selecting, designing, implementing t...

Mites of the genus Rhizoglyphus (Acari: Acaridae) are serious pests plants belonging to orders Liliales and Asparagales such as onions, garlic, lilies, tulips. Their control by synthetic pesticides is becoming problematic a result resistance development in these mites environmental health issues. New pest methods thus need be developed. This review provides an overview studies related bulb mite...

Quantification of soil biological status, through investigation edaphic communities’ composition, constitutes an important factor for the assessment grassland ecosystems, including their protection. The structure invertebrate communities was investigated five grasslands under different chemical and organic treatments, first time in Romania. In order to accomplish this task, some structural para...
