Despite many publications about Chlorella-like algae, their reliable and accurate identification is still difficult due to simplicity high phenotypic plasticity. The molecular approach has revolutionized our understanding of the diversity ’small green balls’, a natural classification this group currently being developed. This work aimed at providing detailed study phylogenetic position, morphol...

This is the first study on phylogenetic relationships in the genus Artemia Leach, 1819 using the pattern and sequence of secondary structures of internal transcribed spacer 1 (ITS1). Significant intraspecific variation in the secondary structure of ITS1 rRNA was found in Artemia tibetiana. In the phylogenetic tree based on joined primary and secondary structure sequences, Artemia urmiana and pa...

background: strongyloides stercoralis , the etiological agent of strongyloidiasis, is one of the most common parasitic nema­tode with the unique ability to complete its life cycle and proliferate within the host. although it is an endemic parasite in iran, no molecular characterization is available on isolates originated from the country. therefore, this study was con­ducted for molecular ident...

We reconstruct a phylogenetic framework for the zygopteran family Lestidae based on molecular dataset comprised of sequence data from genes COI, 16S, 18S, 28S, and ITS1+2 41 ingroup taxa 8 outgroup with emphasis systematic position genus Chalcolestes Kennedy. recover as monophyletic good statistical support. The falls into two subequal clades. One, comprising Sympecma Burmeister Lestes Leach se...

The microalgae, Dunaliella salina was isolated from Maharlu Salt Lake, south east of Shiraz, Iran. The isolated strain was identified by both morphological and physiological markers. The complete ITS region (ITS1 + ITS2) including the 5.8S rDNA gene used as molecular marker confirmed our identification. Growth and cell proliferation, total chlorophyll and carotenoid contents were determined in ...
