Isolation, morphological and molecular characterization of phytate-hydrolysing fungi by 18S rDNA sequence analysis
Phytate is the primary storage form of phosphate in plants. Monogastric animals like poultry, pigs and fishes have very low or no phytase activities in their digestive tracts therefore, are incapable to efficiently utilize phytate phosphorus from the feed. Phytase from microbial sources are supplemented to feedstuff of these to increase the uptake of phytate phosphorus. In the present work effo...
متن کاملSubgenus systematics of Acanthamoeba: four nuclear 18S rDNA sequence types.
Classification of Acanthamoeba at the subgenus level has been problematic, but increasing reports of Acanthamoeba as an opportunistic human pathogen have generated an interest in finding a more consistent basis for classification. Thus, we are developing a classification scheme based on RNA gene sequences. This first report is based on analysis of complete sequences of nuclear small ribosomal s...
متن کاملMolecular characterization of nuclear small subunit (18S)-rDNA pseudogenes in a symbiotic dinoflagellate (Symbiodinium, Dinophyta).
For the dinoflagellates, an important group of single-cell protists, some nuclear rDNA phylogenetic studies have reported the discovery of rDNA pseudogenes. However, it is unknown if these aberrant molecules are confined to free-living taxa or occur in other members of the group. We have cultured a strain of symbiotic dinoflagellate, belonging to the genus Symbiodinium, which produces three dis...
متن کاملInternal phylogeny of the Chilopoda (Myriapoda, Arthropoda) using complete 18S rDNA and partial 28S rDNA sequences.
The internal phylogeny of the 'myriapod' class Chilopoda is evaluated for 12 species belonging to the five extant centipede orders, using 18S rDNA complete gene sequence and 28S rDNA partial gene sequence data. Equally and differentially weighted parsimony, neighbour-joining and maximum-likelihood were used for phylogenetic reconstruction, and bootstrapping and branch support analyses were perf...
متن کاملAn 18S rDNA-based molecular phylogeny of aphidiinae (Hymenoptera: braconidae).
We have obtained a molecular phylogeny of the subfamily Aphidiinae (Hymenoptera: Braconidae) by sequencing the 18S rDNA in 37 aphidiine taxa. Approximately 1857 nucleotides were sequenced in each species. Evolutionary relationships were established by comparing the results of maximum-parsimony, maximum-likelihood, and distance analyses. The most variable region of this gene, V4 (approx 403 nucl...
