“…Givnish et al (2000) also used molecular data to infer the relatively recent evolution of hummingbird pollination from bee-pollinated ancestors in Rapateaceae in the western Guyana Shield. Hummingbird pollination was hypothesized to have arisen three times independently from bee-pollinated ancestors in tribe Antirrhineae (Veronicaceae, sensu Olmstead et al 2001;Ghebrehiwet et al 2000). Similarly, in our broad-scale analyses of phylogenetic relationships within Mimulus and closely related genera, we demonstrated that within the newly redefined Phrymaceae, hummingbird pollination has arisen independently at least three times from insect-pollinated ancestors (Beardsley and Olmstead 2002).…”

Abstract. Species in Mimulus section Erythranthe (monkeyflowers) have become model systems for the study of the genetic basis of ecological adaptations. In this study, we pursued two goals. First, we reconstructed the phylogeny of species in Erythranthe using both DNA sequences from the ribosomal DNA ITS and ETS and AFLPs. Data from rDNA sequences support the monophyly of the section, including M. parishii, but provide little support for relationships within it. Analyses using AFLP data resulted in a well-supported hypothesis of relationships among all Erythranthe species. Our second goal was to reconstruct ancestral pollination syndromes and ancestral states of individual characters associated with hummingbird-pollinated flowers. Both parsimony and likelihood approaches indicate that hummingbird pollination evolved twice in Erythranthe from insect-pollinated ancestors. Our reconstruction of individual characters indicates that corolla color and some aspects of corolla shape change states at the same point on the phylogenetic tree as the switch to hummingbird pollination; however, a switch to secretion of high amounts of nectar does not. Floral trait transformation may have been more punctuational than gradual. Well-resolved species-level phylogenies and estimates of ancestral states are necessary to interpret and understand the evolution of interesting ecological adaptations between species. Ancestral pollination syndromes and character states in hummingbird-pollinated plants have received particular attention from plant evolutionary biologists. Stebbins (1989) estimated that 108 of 129 hummingbird-pollinated taxa in the western United States have sister taxa that are insectpollinated with hummingbird pollination being the derived state. In a review of attempts to use phylogenies to determine the direction of shifts in pollination syndromes, Weller and Sakai (1999) report three studies in which the evolution of hummingbird pollination has been investigated (McDade 1992;Bruneau 1997;Hodges 1997). McDade (1992) found that long, decurved corollas associated with pollination by specialist hermit hummingbirds are ancestral to short corollas associated with pollination by generalist hummingbirds. In the Aphelandra pulcherrima complex, short corollas were hypothesized to have arisen twice. Hummingbird pollination in Erythrina was estimated by Bruneau (1997) to have arisen at least four times from ancestral passerine pollination. Aquilegia species that are pollinated by hummingbirds were hypothesized by Hodges (1997) to be derived from taxa with less-specialized, open, radiate corollas. O'Kane and Schaal (1998) used a molecular phylogeny to infer that hummingbird pollination in Lopezia sect. Jehlia was secondarily regained after a switch to fly pollination. Givnish et al. (2000) also used molecular data to infer the relatively recent evolution of hummingbird pollination from bee-pollinated ancestors in Rapateaceae in the western Guyana Shield. Hummingbird pollination was hypothesized to have arisen three times independ...

“…To allow for the resolution of a purely branching haplotype network ( Figure 5), 12 single-nucleotide polymorphisms that were present in rare haplotypes and not fixed in any species were assumed to be homoplasious to mutations supporting deeper branches. Sequences from Misopates and Chaenorrhinum, each of which has been suggested to be sister to Antirrhinum (Ghebrehiwet et al, 2000;Oyama and Baum, 2004;Vargas et al, 2004), both rooted the Antirrhinum haplotype network in the same position. The network contained four main clades ( Figure 5).…”

SUMMARYThe model species Antirrhinum majus (the garden snapdragon) has over 20 close wild relatives that are morphologically diverse and adapted to different Mediterranean environments. Hybrids between Antirrhinum species have been used successfully to identify genes underlying their phenotypic differences, and to infer how selection acts on them. To better understand the genetic basis for this diversity, we have examined the evolutionary relationships between Antirrhinum species and how these relate to geography and patterns of phenotypic variation in the genus as a whole. Large population samples and both plastid and multilocus nuclear genotypes resolved the relationships between many species and provided some support for the traditional taxonomic division of the genus into morphological subsections. Morphometric analysis of plants grown in controlled conditions supported the phenotypic distinction of the two largest subsections, and the involvement of multiple underlying genes. Incongruence between nuclear and plastid genotypes further suggested that several species have arisen after hybridization between subsections, and that some species continue to hybridize. However, all potential hybrids appear to have retained a phenotype similar to one of their ancestors, suggesting that ancestral combinations of characters are maintained by selection at many different loci.

“…was traditionally placed in the Scrophulariaceae (figwort) family (Sutton 1988). Revisions based on molecular phylogenetic analyses indicated that Linaria would be more appropriately included within the expanded Plantaginaceae (plantain) family (Albach et al 2005;Ghebrehiwet et al 2000;Olmstead et al 2001). L. vulgaris belongs to the Antirrhineae tribe, one of eleven currently circumscribed Plantaginaceae tribes (Estes and Small 2008;Ghebrehiwet et al 2000;Tank et al 2006).…”

Linaria vulgaris Mill. (Plantaginaceae), common or yellow toadflax, is a Eurasian short-lived perennial forb invasive throughout temperate North America. Rhinusa pilosa (Gyllenhal) (Coleoptera, Curculionidae) is a univoltine shoot-galling weevil found exclusively on L. vulgaris in Europe. Under no-choice test conditions, 13 non-native Linaria species exposed to R. pilosa were accepted for oviposition and most were found to be suitable, to varying degrees, for gall and larval development.
