Genome Sequence of the Wild Tomato Species, Solanum pimpinellifolium
نویسندگان
چکیده
We have heard about developments in genome sequencing of key Solanaceae family members, but now it is the wild species turn. Wild species provide a rich resource of genetic diversity and have been integral parts of breeding programs, especially for tomato. The following two articles highlight recent developments in the sequencing of two tomato wild species, Solanum pimpinellifolium, the closest wild progenitor of cultivated tomato, and S. pennellii, an important source of research tools and alleles for breeding. .

Advances in tomato research in the post-genome era
The tomato (Solanum lycopersicum) draft genome, along with a draft of the wild relative, Solanum pimpinellifolium, were released in 2012, almost a decade after the International Tomato Genome project was initiated. Tomato is an important domesticated crop species, as well as a model organism for many aspects of plant biology such as fleshy fruit development, ripening, disease resistance, plant ...
متن کاملGenome-Wide Association Mapping in Tomato (Solanum lycopersicum) Is Possible Using Genome Admixture of Solanum lycopersicum var. cerasiforme
Genome-wide association mapping is an efficient way to identify quantitative trait loci controlling the variation of phenotypes, but the approach suffers severe limitations when one is studying inbred crops like cultivated tomato (Solanum lycopersicum). Such crops exhibit low rates of molecular polymorphism and high linkage disequilibrium, which reduces mapping resolution. The cherry type tomat...

We have identified an accession (LA2093) within the tomato wild species Solanum pimpinellifolium with many desirable characteristics, including biotic and abiotic stress tolerance and good fruit quality. To utilize the full genetic potential of LA2093 in tomato breeding, we have developed a linkage map based on an F(2) population of a cross between LA2093 and a tomato breeding line, using 115 R...
متن کاملComparative genomics and phylogenetic discordance of cultivated tomato and close wild relatives
Background. Studies of ancestry are difficult in the tomato because it crosses with many wild relatives and species in the tomato clade that have diverged very recently. As a result, the phylogeny in relation to its closest relatives remains uncertain. By using the coding sequence from Solanum lycopersicum, S. galapagense, S. pimpinellifolium, S. corneliomuelleri, and S. tuberosum and the genom...

The Hsp20 genes are involved in the response of plants to environment stresses including heat shock and also play a vital role in plant growth and development. They represent the most abundant small heat shock proteins (sHsps) in plants, but little is known about this family in tomato (Solanum lycopersicum), an important vegetable crop in the world. Here, we characterized heat shock protein 20 ...
