Species tree estimation of diploid Helianthus (Asteraceae) using target enrichment

Abstract: The current phylogeny supports three major clades including a large annual clade, a southeastern perennial clade, and another clade of primarily large-statured perennials. Relationships among taxa are more consistent with early phylogenies of the genus using morphological and crossing data than recent efforts using single genes, which highlight the difficulties of phylogenetic estimation in genera known for reticulate evolution. Additionally, conflict and low support at the base of the perennial clades may sug… Show more

“…Annual sunflowers in the genus Helianthus are an excellent system with which to address questions about cytonuclear discordance for a number of reasons. Previous studies have noted cytonuclear discordance in parts of the range of this group (Rieseberg et al ., ,b; Dorado et al ., ; Stephens et al ., ). Recent divergence and large population sizes (Sambatti et al ., ) make incomplete lineage sorting a viable explanation for this discordance.…”

“…(a) Principal components analysis shows continuous variation among species across multivariate trait space (left), as well as a lack of prominent axes of variation across leaf‐level defenses and the HeliaMet metrics of average number of compounds and HeliaMet subset PC 1 (right). (b) Comparison of phylogentic relationships (left, Stephens et al ., ) with dendrogram of defense trait similarity using Ward's clustering algorithm on standardized data (right). Similarity profiling ( SIMPROF ) yields no significant clustering of species (π = 2.55; P = 0.432).…”

“…Phoebanthus tenuifolius seeds were also collected for inclusion in the study as an outgroup for Helianthus (Mason and Donovan ; Stephens et al. ). Of the 58 populations collected in total, 48 were directly collected from wild populations, while 10 were obtained from USDA accessions (nine of which were also directly collected from wild populations; i.e., they had not yet been regrown to maintain seed stocks).…”
