The present investigation was undertaken to describe the relationships among species of Avicenniaceae family which have both economic and medicinal activities, collected in Indian Sundarban by the help of RAPD and ISSR markers. In this study, three different species of Avicennia genus were collected. Frozen young leaves (-200C) were taken to isolate the genomic DNA using a slightly modified CTA...

Schistosomiasis is a disease of global extent reaching populations in social vulnerability. One of the control measures of this parasitosis is the use of molluscicidal substances that can fight snails of the genus Biomphalaria, intermediate hosts of Schistosoma mansoni. The aim of this work was to study the toxic activity of three mangrove species (Avicennia schaueriana Stapf. & Leech, ex Molde...

Determination of gene expression is an important tool to study biological processes and relies on the quality of the extracted RNA. Changes in gene expression profiles may be directly related to mutations in regulatory DNA sequences or alterations in DNA cytosine methylation, which is an epigenetic mark. Correlation of gene expression with DNA sequence or epigenetic mark polymorphism is often d...

The distribution of species of aerobic chemolitho-autotrophic microorganisms such as ammonia-oxidizing bacteria are governed by pH, salinity, and temperature as well as the availability of oxygen, ammonium, carbon dioxide, and other inorganic elements required for growth. Impounded mangrove forests in the Indian River Lagoon, a coastal estuary on the east coast of Florida, are dominated by mang...

Endophytic Sporosarcina aquimarina SjAM16103 was isolated from the inner tissues of pneumatophores of mangrove plant Avicennia marina along with Bacillus sp. and Enterobacter sp. Endophytic S. aquimarina SjAM16103 was Gram variable, and motile bacterium measured 0.6-0.9 μm wide by 1.7-2.0 μm long and light orange-brown coloured in 3-day cultures on tryptone broth at 26°C. Nucleotide sequence of...

The effects of pollution (nutrient enrichment). and the presence of macrovegetation on the species diversity and density of large benthic fauna in the Manukau Harbour, Auckland, were studied by sampling eight soft shore, intertidal habitats. Pollution was found to reduce faunal density but to have only a slight effect on species diversity. The presence of dense meadows of the intertidal seaweed...
