Water is one of the most important elements involved in the creation and development of healthy life. Haphazard disposal of untreated wastewater from households as well as institutions and industry is causing severe deterioration of water bodies in many urban areas in the developing world. There are several methods to treat the municipal wastewater for intended use. One of the methods of the tr...

Harper (1977) has recently stressed the significance of the modular construction of plants. Plants respond to density not so much by changing the proportions of their parts, as by changing the number of basic modules of which they are composed. In the case of deciduous rhizomatous perennials, such as Typha orientalis, the basic module can be defined as a single above-ground shoot and its associ...

The detection of incipient host-shifts is important to the study of emergent diseases because it allows the examination of ecological and genetic conditions that favor novel inter-species transmission. Mixed populations of Silene latifolia and Silene vulgaris were investigated for the putative occurrence of host-shifts by the fungal plant pathogen Microbotryum violaceum (the cause of anther-smu...

BACKGROUND Bacterial Infections involving multi-drug resistant (MDR) phenotypes constitute a worldwide health concern. The present work was designed to assess the antibacterial properties of the methanol extracts of six medicinal plants (Anthocleista schweinfurthii, Nauclea latifolia, Boehmeria platyphylla, Caucalis melanantha, Erigeron floribundus and Zehneria scobra) and the effects of their ...

We used herbarium specimens of Silene virginica, S. caroliniana, S. rotundifolia, and S. latifolia to survey the incidence of anther-smut disease (caused by Microbotryum violaceum sensu lato) in the eastern USA. We found no evidence of a collector bias against diseased specimens. Diseased specimens were frequently found in collections of S. virginica and S. caroliniana, but not in those of S. r...

Most dioecious plant species are believed to derive from hermaphrodite ancestors. The regulatory pathways that have been modified during evolution of the hermaphrodite ancestors and led to the emergence of dioecious species still remain unknown. Silene latifolia is a dioecious plant species harboring XY sex chromosomes. To identify the molecular mechanisms involved in female organ suppression i...

background: natural methods of wastewater treatment, such as wetlands, are simple, cheap and acceptable for developing countries, especially small and remote cities. the aim of this study was to evaluate the efficiency of typha latifolica in subsurface flow constructed wetland for wastewater treatment. methods: in this experimental research, the efficiency of typha latifolica in subsurface flow...
