Molecular marker: Molecular marker is identified as genetic marker. Molecular marker is a DNA or gene sequence within a recognized location on a chromosome which is used as identification tool.

Genetic marker

Received: January 01, Published: ,. Citation: DOI:. Download PDF. Information of the genetic diversity of the threatened tree species in any region of the world may contribute to the creation of effective strategies for their preservation and future use. Nowadays, molecular markers have proven to be invaluable tools for assessing genetic resources of tree plants by improving understanding of the users with regards to the distribution and the extent of genetic variation within and among species. Recently developed marker technologies allow the uncovering of the extent of the genetic variation in an unprecedented way through increased coverage of the genome. Markers have diverse applications in plant sciences, but certain marker types, due to their inherent characteristics, have also shown their limitations.

DNA marker applications to molecular genetics and genomics in tomato

Tomato is an important crop and regarded as an experimental model of the Solanaceae family and of fruiting plants in general. To enhance breeding efficiency and advance the field of genetics, tomato has been subjected to DNA marker studies as one of the earliest targets in plants. The developed DNA markers have been applied to the construction of genetic linkage maps and the resultant maps have contributed to quantitative trait locus QTL and gene mappings for agronomically important traits, as well as to comparative genomics of Solanaceae. The recently released whole genome sequences of tomato enable us to develop large numbers of DNA markers comparatively easily, and even promote new genotyping methods without DNA markers. In addition, databases for genomes, DNA markers, genetic linkage maps and other omics data, e. The use of DNA marker technologies in conjunction with new breeding techniques will promise to advance tomato breeding. DNA markers have promoted genetics, genomics and breeding in a wide range of plant species, including tomato, through their use in the construction of high-density linkage maps, which are a useful tool for marker-assisted selection, association analysis and QTL analysis.

Plant Breeding from Laboratories to Fields. Molecular breeding MB may be defined in a broad-sense as the use of genetic manipulation performed at DNA molecular levels to improve characters of interest in plants and animals, including genetic engineering or gene manipulation, molecular marker-assisted selection, genomic selection, etc. More often, however, molecular breeding implies molecular marker-assisted breeding MAB and is defined as the application of molecular biotechnologies, specifically molecular markers, in combination with linkage maps and genomics, to alter and improve plant or animal traits on the basis of genotypic assays.

    Several characteristics of molecular markers make them useful to geneticists.
