Micro satellite mapping of plant genomes

Abstract

Micro satellites are DNA markers, based on the repeated nucleotide sequences number polymorphism. They belong to a group of PCR markers and are mainly used as an addition to other types of markers. Their characteristics and technical aspects of their application are discussed in the present study. Furthermore, some results obtained by the use of the micro satellite DNA in genetic mapping of plant genomes are also presented. Although micro satellites provide the identification of genotypes within a species, inadequacy of comparative mapping of different species is their serious blemish.

Mikrosateliti su DNA markeri, zasnovani na polimorfizmu broja repetitivnih sekvenci nukleotida. Spadaju u grupu PCR-markera i koriste se uglavnom kao dopuna drugim tipovima markera. Njihove odlike i tehnička strana primene diskutovani su u ovom radu. Navedeni su neki rezultati dobijeni korišćenjem mikrosatelitske DNA u genetičkom mapiranju biljnih genoma. Iako mikrosateliti omogućuju identifikaciju genotipova unutar jedne vrste, njihov nedostatak je da nisu pogodni za komparativno mapiranje različitih vrsta.
