Solanum chilense represent separately evolving populations, and conceal at least one undescribed cryptic species. CONCLUSIONS: Despite its vast economic importance, Solanum sect. Lycopersicon still exhibits considerable taxonomic instability. A pattern of under-recognition of outcrossing
Mar 30, 2021 · Despite its vast economic importance, Solanum sect. Lycopersicon still exhibits considerable taxonomic instability. A pattern of under-recognition of outcrossing species may be common, not only in tomatoes, but across flowering plants. We discuss the possible causes and implications of this observation, with a focus on macroevolutionary inference.

Jun 14, 2020 · of all species in Solanum section Lycopersicon (Chetelat et al. 2009). 115 Taxonomy of S. chilense has undergone numerous changes (Rick and Lamm 1955; Peralta et al. 2008). The original description of Lycopersicon chilense Dunal relied on the earliest known collection of S. chilense, sampled by Gaudichaud in 1839 (Rick and Lamm

Mar 30, 2021 · Study organism. Solanum chilense (Dunal) Reiche plants are herbaceous perennials with a woody base, erect or decumbent growth, 0.5 to 1.5 m tall and 1 m wide when found isolated along cliff- and roadsides, but commonly spreading to 2 to 4 m (or more) inside deep Andean volcanic canyons carved by snowmelt and sparse rain.

The six AFLP primer combinations produced 245 fragments, distributed between 60 and 380 bp, of which 221 (90.2%) were polymorphic. A marker was considered polymorphic at the 1% level. Multiple alignment of CT66 sequences resulted in a matrix of 665 bp, of which 96 (14.4%) were polymorphic. There was no variation in sequence length among taxa for th...
The accessions studied in the present work were either collected by the authors on different collection expeditions or obtained from genebanks. We have reclassified some of them, especially those belonging to S. peruvianum s.l., into new species (S. peruvianum s.str., S. corneliomulleri, S. arcanum and S. huaylasense). This reclassification was car...
The accessions clustered together in groups that corresponded to the different species. In some cases though there were single species divided in two groups or two species were merged together. S. arcanum accessions did not form a monophyletic cluster in any case. In the AFLP tree, they were distributed between two clusters that corresponded clearl...
The AFLP tree and CT66 phylogram turned out to be rather uninformative regarding relationships among species, whereas the CT179 phylogram presented a more defined structure that suggested some intriguing phylogenetic hypotheses for future testing. The data presented clearly confirmed the close relationship among S. lycopersicum, S. cheesmaniae, S. ...

Solanum chilense is a robust, perennial, herbaceous plant that at first grows erect, later lying. It reaches up to 1 metre (3 ft 3 in) high; its foliage reaches a similar diameter. It is found on rocky sites. The grayish stems become woody at the base and reach a diameter of 8 to 12 millimetres (0.31 to 0.47 in).
Mar 7, 2024 · Three common tomato pathogen species—Alternaria solani, Phytophthora infestans, and Fusarium oxysporium—were also tested on different S. chilense populations, and the results showed large variations and mosaic resistance patterns that were unrelated to their geographic locations (Stam et al., 2017), where the quantitative variation of ...
