Population genetics of speciation in two closely related wild tomatoes (Solanum section Lycopersicon).
We present a multilocus sequencing study to assess patterns of polymorphism and divergence in the closely related wild tomato species, Solanum peruvianum and S. chilense (Solanum section Lycopersicon, Solanaceae). The data set comprises seven mapped nuclear loci (approximately 9.3 kb of analyzed sequence across loci) and four local population samples per species that cover much of the species' ...
متن کاملPopulation Genomics in Wild Tomatoes—The Interplay of Divergence and Admixture
Hybridization between closely related plant species is widespread, but the outcomes of hybridization are not fully understood. This study investigates phylogenetic relationships and the history of hybridization in the wild tomato clade (Solanum sect. Lycopersicon). We sequenced RNA from individuals of 38 different populations and, by combining this with published data, build a comprehensive gen...
متن کاملContribution to the molecular systematics of the genus Capoeta from the south Caspian Sea basin using mitochondrial cytochrome b sequences (Teleostei: Cyprinidae)
Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...
متن کاملUsing multilocus sequence data to assess population structure, natural selection, and linkage disequilibrium in wild tomatoes.
We employed a multilocus approach to examine the effects of population subdivision and natural selection on DNA polymorphism in 2 closely related wild tomato species (Solanum peruvianum and Solanum chilense), using sequence data for 8 nuclear loci from populations across much of the species' range. Both species exhibit substantial levels of nucleotide variation. The species-wide level of silent...
متن کاملComparative transcriptome analysis of the different tissues between the cultivated and wild tomato
Although domesticated tomato is cultivated by wild tomato, there are a lot of differences between cultivated tomato and wild tomato, such as shape, physiological function and life history. Many studies show that wild tomato has better salt resistance and drought resistance. In addition to, domesticated tomato's fruit is bigger and has more nutritious than wild tomato. The different features are...
