The economic importance of Solanaceae plant species is well documented and tomato has become a model for functional genomics studies. In plants, important processes are regulated by microRNAs (miRNA). We describe here a data base integrating genetic map positions of miRNA-targeted genes, their expression profiles and their relations with quantitative fruit metabolic loci . Tomato (Solanum lycopersicon L.), a new world solanaceous plant is an excellent model for plant genomic genus Solanum is one of the largest angiosperm genera and the genome genes spread over 12 chromosomes and has few high copy number long terminal repeat (LTR) retrotransposons and largely comprised of low-copy DNA [].The genome .

BackgroundMany highly beneficial traits (e.g. disease or abiotic stress resistance) have been transferred into crops through crosses with their wild relatives. The 13 recognized species of tomato (Solanum section Lycopersicon) are closely related to each other and wild species genes have been extensively used for improvement of the crop, Solanum lycopersicum L.

The sequences were heterogeneous, only 3 of the 16 being identical and the most diverse showing / pairwise nucleotide differences.

Multiple alignment and construction of neighbor joining trees divided the sequences into six groups, three comprising five, three, and five sequences respectively, and the other three containing a single Cited by: Based on analysis of transposon flanking sequences, an Ac insertion into a genomic region exhibiting substantial homology to LePT1 (Y, AF), LePT2, and other plant Pi transporters was identified.

The gene was named Lycopersicon esculentum Pi transporter 4 (LePT4; AY). Eventually, a genomic fragment of bp was cloned by. Interspecific Reproductive Barriers (IRBs) prevent hybridization between species, and in plants IRBs are often linked to mating system.

Many wild species of tomato (Solanum sect. Lycopersicon) display S-RNase-based gametophytic self-incompatibility (SI), whereas others are self-compatible (SC). The phylogenetic classification of the Solanaceae has been recently revised and the genus Lycopersicon re-integrated into the Solanum genus with its new nomenclature.

Solanum section Lycopersicon includes the cultivated tomato (S. lycopersicum) and 12 additional wild relatives. Solanum lycopersicum is the only domesticated species (Peralta et. High‐quality genome sequences of S. lycopersicum and S. pennellii have been obtained (The Tomato Genome Consortium, ; Bolger et al., ); these sequences enable analysis of sequence diversity and evolutionary patterns of lncRNA genes in these two closely related tomato species.

In this study, Lycopersicon‐specific lncRNAs are defined. Begomovirus isolate YN was obtained from Solanum lycopersicon plants showing leaf curl symptoms collected in Yuanmou, Yunnan province. Complete sequence of the single circular DNA-A molecule comprised nucleotides and contains six open reading frames.

Comparison and analysis showed that total DNA-A of YN was most closely related to Papaya leaf curl. The other 5 sequences were retrieved from GenBank (Solanum tuberosumX [van der Leij et al.

]; Capsicum baccatum var. baccatumAF, Capsicum cardenasiiAF, Lycianthes lycioidesAF, and Lycianthes rantonneiAF [Walsh and Hoot ]). For more taxa information, see supplementary table 1 in Supplementary Material online. Only one clone contained a full CP sequence that showed 65 to 94% sequence identity to fragments of CP sequences from other clones.

The identity between DNA sequences derived from the same species (rsicum or haites) was generally not higher than between species.

Thus, in the subset of clones analyzed, no species-specific. In EST-based predictions, EST sequences of 11 Solanum species were aligned against the potato genome using BLAT (identity ≥, coverage ≥) to. The first three species belong to the Solanaceae family.

The other species were chosen to represent a diverse set of families throughout the plant kingdom. Genomic DNA of each species was digested with EcoRI; ∼3 μg of tomato, μg of Arabidopsis, and 10 μg of the other species was run on an electrophoresis gel and DNA gel blotted.

The most diverse wild tomato species Solanum peruvianum sensu lato (s.l.) has been reclassified into four separate species: Solanum peruvianum sensu stricto (s.s.), Solanum corneliomuelleri, Solanum huaylasense, and Solanum r, reproductive barriers among the species are incomplete and this can lead to discrepancies regarding genetic identity of germplasm.

Acylsugars are synthesized in the glandular trichomes of the Solanaceae family and are implicated in protection against abiotic and biotic stress. Acylsugars are composed of either sucrose or glucose esterified with varying numbers of acyl chains of differing length. In tomato (Solanum lycopersicum), acylsugar assembly requires four acylsugar acyltransferases.

T-DNA in other Nicotiana species. The genus Nicotiana is one of the largest genera in the Solanaceae and contains 75 species that are characterized by a wide range of variations among their floral and vegetative morphology (Clarkson et al., ).The different Nicotiana species evidence interspecific crosses which complicates Nicotiana phylogeny.

The earliest studies comparing small samples of S-RNase sequences from differ-ent Solanaceae (e.g. species of Petunia, Nicotiana and Solanum sect. Lycopersicon) found strong evidence of ancestral polymorphism shared among the taxa sampled (Ioerger et al.

Bidirectional gel electrophoresis revealed the presence of a viroid-like RNA. The same viroid was detected in healthy-looking pepino plants (Solanum muricatum) growing in the same. The tomato (Solanum lycopersicum) is a herbaceous, usually sprawling plant in the nightshade family that is typically cultivated for its edible fruit.

Savory in flavor (and accordingly termed a vegetable; see below), the fruit of most varieties ripens to a distinctive red plants typically reach to 1–3 metres (3–10 ft) in height, and have a weak, woody stem that often vines. Enhanced Disease Susceptibility1 (EDS1) is a nucleo-cytoplasmic protein, known to be a key regulator of plant basal defense andeffector-triggered immunity.

Sequence of a single copy brinjal EDS1 gene (SmEDS1) was mined from draft brinjal genome extracted sequence was found to be incomplete and polished with the help of transcriptome sequence data. The other species of Lycopersicon have also been assigned or re-assigned to Solanum. More recent studies (Bohs and Olmstead ; Olmstead and Palmer ) have provided additional evidence for the inclusion of the tomato in Solanum.

The tomatoes are placed in Solanum in groups very close to the tuberous and non-tuberous potatoes. This has not. We focused on five species representing the phylogenetic diversity of the Convolvulaceae: I. purpurea, C. arvensis, E. glomeratus, Merremia dissecta and Merremia umbellata, and S. lycopersicon.

Genetic diversity underlies the improvement of crops by plant breeding. Landraces of tomato (Solanum lycopersicum L.) can contain valuable alleles not common in modern aim was to measure genetic diversity present in 47 most common tomato varieties grown in Italy, 35 were varieties used for processing and 12 were landraces considered “salad varieties”.Glandular trichomes from tomato (Solanum lycopersicum) and other species in the Solanaceae produce and secrete a mixture of O -acylsugars (aliphatic esters of sucrose and glucose) that contribute to insect defense.

Despite their phylogenetic distribution and diversity, relatively little is known about how these specialized metabolites are synthesized.

Hunziker () is the most recent work to include keys to genera, although he does not recognise many of the genera included here as members of the Solanaceae.
