Mycosporine- like amino acids (MAAs) are small (<400Da), colourless, water soluble compounds composed of cyclohexenone or cyclohexinimine chromophere conjugated with the nitrogen substituent of amino acid or its amino alcohol. These compounds are known for their UV- absorbing role in various organisms and seem to have evolutionary significance. The biosynthesis of MAAs is presumed to occur via ...

In this study, 10 species of Bipolaris viz.B. bicolor, B. cynodontis, B. cylindrica, B. hawaiiensis,B. prieskaensis, B. sorghicola, B. sorokiniana,B. spicifera, B. zeae and B. zeicola and four species of Curvularia viz.C. fallax, C. heteropogonicola, C. inaequalis and C. lunata were identified on graminicolous species or soil. Bipolaris cylindrica, B. prieskaensis, B. zeae,C. fallax and C. hete...

Phylogenetic Analysis of Some Indigenous and Non-Indigenous Luffa (Luffa cylindrica) Genotypes using ITS Marker

Inference of genetic structure and demographic history is fundamental issue in evolutionary biology. We examined the levels and patterns of genetic variation of a widespread mangrove species in the Indo-West Pacific region, Bruguiera gymnorrhiza, using ten nuclear gene regions. Genetic variation of individual populations covering its distribution range was low, but as the entire species it was ...

Abstract: Using polymorphic loci of allozyme as genetic marker and horizontal sliceable gel electrophoresis as method to examine the genotypes of 4 Bruguiera gymnorrhiza populations in Fugong of Fujian (24°24′), Futian of Guangdong (22°32′), Shankou of Guangxi (21°28′) and Dongzhai Harbor of Hainan (19°51′), China. The mating system was also decided by Multi Locus Testing. The polymorphic loci ...

The objective of present study is to determine seasonal changes in biochemical content freshwater bivalve, Parreysia cylindrica relation heavy metal pollution Jayakwadi reservoir. Heavy concentrations were determined seasonally from surface water, soil sediment and soft body tissues cylindrica. highest during summer season than winter monsoon season. Protein, DNA, RNA Ascorbic acid estimated su...

Mangrove is a type of plant that can survive on muddy substrates and at relatively high levels water salinity. Information about the ecological value mangrove very important, in order to provide an overview current condition mangrove. The purpose this study determine structure community regional marine conservation area Gili Sulat. This used quadratic transect method measures are 10 m x (tree c...

The cyanobacteria Anabaena cylindrica and Synechococcus leopoliensis (= Anacystis nidulans) were grown at different levels of UV-B radiation (439, 717, 1230 and 1405 J m “2d_ l, weighted according Caldwell. 1971) for 2 days. Dry weight was hardly affected but phycocyanin content of both species decreased linearly to the level o f UV -B radiation.
