Application of DNA Molecular Markers in Plant Breeding (Review article)
Plant Breeding has utilized a wide range of techniques and methods to improve the quality and quantity of plants. The molecular markers are the tools that have provided a new perspective for plant breeding advancements. This article has reviewed the various advantages and uses of molecular markers and the utilization of the high potential of natural polymorphisms within communities, combined wi...
متن کاملDNA variation in the wild plant Arabidopsis thaliana revealed by amplified fragment length polymorphism analysis.
To investigate the level and pattern of DNA variation of Arabidopsis thaliana at the entire genome level, AFLP analysis was conducted for 38 ecotypes distributed throughout the world. Ten pairs of selective primers were used to detect a total of 472 bands, of which 374 (79. 2%) were polymorphic. The frequency distribution of polymorphic bands was skewed toward an excess of singleton variation. ...
متن کاملOGG1 DNA Repair Gene Polymorphism As a Biomarker of Oxidative and Genotoxic DNA Damage
Background: Single nucleotide polymorphisms in 8-oxoguanine DNA glycosylase-1 (OGG1) gene modulates DNA repair capacity and functions as one of the first lines of protective mechanisms against 8-hydroxy-2’-deoxyguanosine (8-OHdG) mutagenicity. OGG1-Cys326 gene polymorphism may decrease DNA repair function, causing oxidative stress due to higher oxidative DNA damage. The main purpose of this stu...
متن کاملDNA polymorphism at the cytosolic phosphoglucose isomerase (PgiC) locus of the wild plant Arabidopsis thaliana.
DNA variation in a 4.7-kb region of the cytosolic phosphoglucose isomerase (PgiC) locus was investigated for 21 ecotypes of Arabidopsis thaliana. The estimated nucleotide diversity was 0.0038, which was one-third of those in previously investigated loci. Since most of the nucleotide variations (93%) were singleton and doubleton, Tajima's test statistic was significantly negative. About 50% of n...
متن کاملDNA polymorphism at the ACAULIS5 locus of the wild plant Arabidopsis thaliana.
Nucleotide variation in the ACL5 gene region, which encodes spermine synthase, was analyzed for 21 Arabidopsis thaliana ecotypes and one accession of Arabis gemmifera. In A. thaliana, dimorphism was also detected in the ACL5 region, as in other nuclear genes of this plant. The nucleotide diversity (pi) of the entire region, exon and intron was 0.0163, 0.0042 and 0.0293, respectively. The level ...
