Tomato Molecular Markers

Abstract

SummaryTomato (Solanum lycopersicum L.) is one of the most popular vegetable grown in many regions of the world. Due to its high taste quality and nutritional value increase interest in the cultivation of this species and its consumption. Using the latest achievements in fields of genetics, molecular biology and biotechnology, breeders can create new varieties with improved useful traits. Introduction of DNA markers, especially those based on the polymerase chain reaction (PCR) has led to breakthrough in the plants genetic research, including tomato. They are successfully used for plant genomes mapping, phylogenetics studies, selection of parental forms in plant breeding, and above all to identify the genes of important traits. For tomato have been identified and mapped 9309 molecular markers. High-density genetic maps development gives an opportunity to use them in genetic research and breeding programs. Identification of DNA markers closely linked to studied gene can significantly facilitate the identification of desirable traits in material breeding, or accelerate the plants selection for elimination of genotypes with undesirable genes. Material breeding selection using molecular markers, defined as MAS (marker-assisted-selection) is increasingly being used in tomato breeding programs, contributing to facilitated identification of genes or QTL and their transfer into the cultivated species from wild form.

Use of Multispectral Imaging in Varietal Identification of Tomato

“…However, intensive modern breeding technology has created a narrow genetic diversity resulting in lack of minimum phenotypic variation among the germplasm making morphological markers insufficient and extremely difficult to use for identification. Several methods such as biochemical (protein) markers [ 4 , 5 ] and molecular markers [ 6 – 10 ] have been investigated and developed for robust identification and characterization of tomato germplasm. However, these methods are costly, destructive and time consuming, and to overcome these shortcomings and to meet the modern crop production demands, technologies which are quick and reliable in identifying the tomato varieties for technical and economic aspects are desirable and beneficial [ 11 ].…”

A Simple and Effective Bioassay Method Suitable to Comparative In Vitro Study of Tomato Salt Tolerance at Early Development Stages

“…In addition to its great practical value, the tomato has been widely used as a model plant in various basic research investigated the underlying the mechanisms of plant resistance to abiotic stresses, including salinity [4,5]. This is due to the large number of morphological traits clearly identifiable at different ontogenetic stages [6,7], detailed molecular genetic maps [8,9], and reproducible in vitro tissue culture techniques [10,11].…”
