Abstract • Background and Aims Aglaonema is an important ornamental foliage plant genus, but genetic relationships among its species and cultivars have not been reported. This study analysed genetic relatedness of 54 cultivars derived from nine species using amplified fragment length polymorphism (AFLP) by:
A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from one to six or more base pairs) are repeated, typically 5–50 times. Microsatellites occur at thousands of locations within an organism's have a higher mutation rate than other areas of DNA leading to high genetic atellites are often referred to as short tandem repeats. Hybridization Based DNA Markers. Restriction fragment length polymorphism (RFLP) markers reveal the differences among individuals by variation in the size of DNA fragments produced by restriction enzymes .These markers enabled DNA variations to be tested as substitutions of a single base in the recognition sequence of a restriction enzyme altered the length of resultant restriction Cited by:
PCR-based markers PCR is one of the most consistent and advanced scientific techniques of all historical innovations. It is a molecular biology-based technique intended for enzymatically replicating (amplifying) a very small quantity of DNA without using a living organism.

The use of random primers overcame the limitation of prior sequence knowledge for PCR analysis and being applicable to all organisms, facilitated the development of genetic markers for a variety of purposes.
PCR-based techniques can further be subdivided into two subcategories: (1) arbitrarily primed PCR-based techniques or sequence non Cited by: Genetic markers are essential when developing or working with genetically variable populations.
Indel Group in Genomes ([IGG]) markers are primer pairs that amplify single-locus sequences that differ in size for two or more alleles. They are attractive for their ease of use for rapid genotyping and their codominant nature. Here, we describe a heuristic algorithm that uses a k-mer Cited by: 3.
DNA-based markers were developed and are being used in Musa, representing powerful tools to assess the genetic diversity and clarify the individual genetic characteristics and relationships. Researchers should select the best marker for a certain task; however, the recently developed molecular markers were more informative when applied in by: 2.
Molecular markers have three-fold applications in gene mapping: (i) a marker allows the direct identification of the gene of interest instead of the gene product, and consequently it serves as a useful tool for screening somatic cell hybrids; (ii) use of several DNA probes and easy-to-screen techniques, a marker also helps in physical mapping of the genes using in situ hybridization; and (iii Cited by: 1.
RFLP - RESTRICTION FRAGMENT LENGTH POLYMORPHISM RFLP & is very useful study in Genomic DNA Sequence. RFLP has been developed for chromosomes mapping of humans, mice, maize, tomato,rice,etc.
