aquatic plants have a major influence upon other aquatic organisms, by altering both water chemistry and spatial structure of the habitat in shallow water bodies. some of them, such as stratiotes aloides l., may suppress algal growth. but how aquatic plants would ultimately influence the heterotrophic community and the aquatic ecosystem as a whole is far from clear. our microcosm-based study de...

three extracts of pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. some of these extracts were found to be active against some bacterial strains. the methanolic extract exhibited a superior level of antibacterial activity. all of the extracts were active against vibrio chlorea.

a greenhouse experiment was conducted to investigate the effects of mycorrhial fungus (glomus mosseae) on cadmium (cd) toxicity in pepper (capsicum annuum l. cv. zhongjiao 105) plants. half of plants were inoculated with arbuscular mycorrhizal fungi (amf). cd was supplied in the form of cadmium chloride at 0.0, 0.1 and 0.5 mm through irrigation water in the soil. mycorrhizal colonization was hi...

Desiccation-tolerance (DT) evolved as the key solution to survival on land by the early algal ancestors of terrestrial plants. This 'first' DT involved utilizing rapidly mobilisable repair mechanisms and is still found today in mosses, such as Tortula ruralis, and ferns, such as Mohria caffrorum. The first seed plants lost vegetative DT while investing their seeds with tolerance mechanisms impr...
