Fig. 2 in Morphological trait evolution in Solanum (Solanaceae): Evolutionary lability of key taxonomic characters
Fig. 2. Phylogeny of Solanum highlighting the informally named infrageneric clades based on Bayesian analysis of 742 Solanum species (60% of total known diversity) with two nuclear and seven plastid regions by Gagnon & al. (2022). Infrageneric clades are colour-coded and numbered reflecting the currently recognised major and minor clades of Solanum (Table 1): bright red shades highlight minor clades within VANAns clade, dark reds DulMo, blues Potato clade, purples Brevantherum, orange shades Geminata, yellows Cyphomandra, purple Wendlandii-Allophyllum, pink Nemorense, and green shades indicate minor clades within the large Leptostemonum clade. Nodes without circles have maximum branch support (1.0 posterior probability), nodes with black circles strong support (≥0.95), and nodes with white circles moderate to weak support (0.75–0.94). Dashed lines indicate nodes with nuclear-plastome discordance highlighted in Gagnon & al. (2022) collapsed in our analyses. A, Minor clades 1–7 (Thelopodium, Valdiviense, ANS [African Non-Spiny], Normania, Archaeosolanum, Dulcamaroid, Morelloid); B, Minor clades 8–17 (Regmandra, Pteroidea, Herpystichum, S. oxycoccoides, Anarrichomenum, Articulatum, Basarthrum, Etuberosum, Tomato, Petota); C, Minor clades 18–27 (S. anomalostemon, Trachytrichium, Gonatotrichum, Inornatum, Brevantherum, Reductum, Geminata, S. graveolens, Cyphomandropsis, Pachyphylla); D, Minor clades 28–46 (Allophyllum, Wendlandii, Nemorense, S. polygamum, Acanthophora, Lasiocarpa, Gardneri, Thomasiifolium, Erythrotrichum, Sisymbriifolium, Crinitum, Androceras, S. campechiense, Carolinense, Bahamense, Micracantha, Asterophorum, S. multispinum, Torva); E, Minor clades 47–49 (S. euacanthum, Elaeagnifolium, EHS [Eastern Hemisphere Spiny]).
Fig. 7 in Morphological trait evolution in Solanum (Solanaceae): Evolutionary lability of key taxonomic characters
Fig. 7. Evolution of conserved morphological traits in Solanum with 10–49 transitions based on species-level analysis using stochastic character mapping. A, Corolla bilateral symmetry; B, Anther shape; C, Pedicel articulation; D, Fruit type; E, Stone cells. Results from the best model are shown for each character (see Table 1 and suppl. Table S4 for details) based on 200 simulations. The topology used for mapping was derived from a supermatrix phylogeny with nine loci (two nuclear and seven plastid loci; Gagnon & al., 2022) with 725 species sampled and coded for each trait (58% of all species). All minor clades are labelled; tips reflect the crown nodes of each minor clade. Piecharts indicate likelihood of modelled ancestral states along the nodes, and frequency bars (tips) reflect proportion of species sampled within each clade with each state.
Fig. 6 in Morphological trait evolution in Solanum (Solanaceae): Evolutionary lability of key taxonomic characters
Fig. 6. Evolution of labile morphological traits (reproductive) in Solanum with 50–100 transitions based on species-level analysis using stochastic character mapping. A, Inflorescence position; B, Inflorescence branching; C, Sexual system; D, Stamen heteromorphism; E, Trichomes on mature fruits; F, Fruiting calyx modifications. Results from the best model are shown for each character (see Table 1 and suppl. Table S4 for details) based on 200 simulations. The topology used for mapping was derived from a supermatrix phylogeny with nine loci (two nuclear and seven plastid loci; Gagnon & al., 2022) with 725 species sampled and coded for each trait (58% of all species). All minor clades are labelled; tips reflect the crown nodes of each minor clade. Piecharts indicate likelihood of modelled ancestral states along the nodes, and frequency bars (tips) reflect proportion of species sampled within each clade with each state.
