A Solution for Universal Classification of Species Based on Genomic DNA
نویسندگان
چکیده
Traditionally, organisms have been classified on the basis of their phenotype. Recently, genotype-based classification has become possible through the development of sequencing technology. However, it is still difficult to apply sequencing approaches to the analysis of a large number of species due to the cost and labor. In most biological fields, the analysis of complex systems comprising various species has become an important theme, demanding an effective method for handling a vast number of species. In this paper, we have demonstrated, using plants, fish, and insects, that genome profiling, a compact technology for genome analysis, can classify organisms universally. Surprisingly, in all three of the domains of organisms tested, the phylogenetic trees generated from the phenotype topologically matched completely those generated from the genotype. Furthermore, a single probe was sufficient for the genome profiling, thereby demonstrating that this methodology is universal and compact.

Searching the genome of beluga(Husohuso) for sex markers based on targeted Bulked SegregantAnalysis (BSA)
In sturgeon aquaculture, where the main purpose is caviar production, a reliable method is needed to separate fish according to gender. Currently, due to the lack of external sexual dimorphism, the fish are sexed by an invasive surgical examination of the gonads. Development of a non-invasive procedure for sexing fish based on genetic markers is of special interest. In the present study we empl...
متن کاملSpecific Primers For Identification and Detection of Three Major Desert Truffle Species in Iran with Special Reference to Terfezia claveryi
ABSTRACT- Desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. A PCR-based method was developed for the identification of 3 major desert truffles of Iran: Terfezia claveryi, Tirmania pinoyi and Tirmania nivea based on internal transcribed spacers of rDNA. Two specific PCR primers were designed for T. claveryi, 4 for T. pinoyi, and 2 for ...

Background and aim: Dermatophytosis (tinea, ringworm) is the infection of skin, hair or nail that is caused by various keratinophilic fungi (dermatophytes). Dermatophytosis is a common infection throughout the world including all parts of Iran. As conventional laboratory procedures for identification of different dermatophytes are slow or lack specificity, more rapid and reliable methods are st...

An efficient DNA isolation protocol specifically modified to get pure quality DNA required for molecular studieshas been reported in this paper. Some aquatic plants (Potamogeton spp., Ceratophyllum demersum and Myriophyllum spicatum) were used for the study. The protocol developed will be useful in getting high and pure DNA. Instead of using the available DNA extraction kits, this protocol can ...

Picoa species are hypogeous desert truffles, which can be found in semi-arid ranges of North Africa, West Asian, South of Europe and Middle East, including Iran (Moreno et al. 2000, Jamali & Banihashemi 2012, 2013). Picoa species form symbiosis mainly on roots of annual and perennial herbaceous plants of the Helianthemum, including H. ledifolium and H. salicifolium var. salicifolium (Jamali & B...
