Mangrove forests are salt tolerant plants confined to the coastal areas and occupy only 5% of the total forest areas of the
world. These are the most hostile environment with fluctuating tidal and saline regime and a limited plant species can survive
under such condition. Nevertheless, these plants are most valuable resources and provide economic and ecological benefits
to the coastal people. Several mangrove species have been used in traditional medicine or have few applications as insecticide
and pesticide. Mangroves are biochemically unique, producing wide array of natural products with unique bioactivity. They
possess active metabolites with some novel chemical structures which belong to diverse chemical classes such as alkaloids,
phenol, steroids, terpenoids, tannins, etc. The present review examines recent investigations on the biological activities
of extracts and phytochemicals identified from mangroves and their associates as antimicrobial, antiviral, antioxidant, anticancer
and many other properties like antiproliferative, insecticidal, antimalarial, antifeedant, central nervous system depressant
and anti-plasmodial etc. The present article also emphasizes and creates an awareness of potential mangroves and their associates
as a source of novel medicines, agrochemicals and source of many biologically active compounds. 相似文献

The LWRs (length–weight relationships) of four freshwater fish species from medium categorized Doyang reservoir at Wokha District, Nagaland were studied, namely as Garra naganensis Hora, 1921; Devario naganensis Chaudhuri, 1912; Chagunius nicholsi Myers, 1924 and Schistura manipurensis Chaudhuri, 1912. Fish sample were collected in every 15 days interval by cast-nets (1.0 × 1.0 cm mesh size covering the 4.5 m2 areas), gill-nets (0.4–5.0 cm mesh size), scoop-nets (mesh size with 0.3 × 0.3 cm to 0.6 × 0.6 cm) and also from the local fishermen in between July 2017 to January 2019. The regression value of slope (b) is fallen into 2.860–3.115 range with significant correlation values (r2 ≥ .960). 相似文献

Analysis of protein sequences from Mycobacterium tuberculosis H37Rv(Mtb H37Rv) was performed to identify homopeptide repeatcontaining proteins(HRCPs).Functional annotation of the HRCPs showed that they are preferentially involved in cellular metabolism.Furthermore,these homopeptide repeats might play some specific roles in protein-protein interaction.Repeat length differences among Bacteria,Archaea and Eukaryotes were calculated in order to identify the conservation of the repeats in these divergent kingdoms.From the results,it was evident that these repeats have a higher degree of conservation in Bacteria and Archaea than in Eukaryotes.In addition,there seems to be a direct correlation between the repeat length difference and the degree of divergence between the species.Our study supports the hypothesis that the presence of homopeptide repeats influences the rate of evolution of the protein sequences in which they are embedded.Thus,homopeptide repeat may have structural,functional and evolutionary implications on proteins. 相似文献
