A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive genus-level sampling and provides a framework phylogeny for the entire family that helps integrate many previously-published phylogenetic studies within So- lanaceae. The four genera comprising the family Goetzeaceae and the monotypic families Duckeodendraceae, Nolanaceae, and Sclerophylaceae, often recognized in traditional classifications, are shown to be included in Solanaceae. The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive “x = 12” clade, which includes Nicotiana and the Australian tribe Anthocercideae. These results also provide greater resolution among lineages within Solanoideae, confirming Jaltomata as sister to Solanum and identifying a clade comprised primarily of tribes Capsiceae (Capsicum and Lycianthes) and Physaleae.

  • (Trnf) Pseudogenes Defines a Distinctive Clade in Solanaceae Péter Poczai* and Jaakko Hyvönen
    Poczai and Hyvönen SpringerPlus 2013, 2:459 http://www.springerplus.com/content/2/1/459 a SpringerOpen Journal SHORT REPORT Open Access Discovery of novel plastid phenylalanine (trnF) pseudogenes defines a distinctive clade in Solanaceae Péter Poczai* and Jaakko Hyvönen Abstract Background: The plastome of embryophytes is known for its high degree of conservation in size, structure, gene content and linear order of genes. The duplication of entire tRNA genes or their arrangement in a tandem array composed by multiple pseudogene copies is extremely rare in the plastome. Pseudogene repeats of the trnF gene have rarely been described from the chloroplast genome of angiosperms. Findings: We report the discovery of duplicated copies of the original phenylalanine (trnFGAA) gene in Solanaceae that are specific to a larger clade within the Solanoideae subfamily. The pseudogene copies are composed of several highly structured motifs that are partial residues or entire parts of the anticodon, T- and D-domains of the original trnF gene. Conclusions: The Pseudosolanoid clade consists of 29 genera and includes many economically important plants such as potato, tomato, eggplant and pepper. Keywords: Chloroplast DNA (cpDNA); Gene duplications; Phylogeny; Plastome evolution; Tandem repeats; trnL-trnF; Solanaceae Findings of this region.

Solanum section Cyphomandropsis (Solanaceae) includes 13 species native to South Amer ica. Plants of this section are woody shrubs to small trees that lack spines, are glabrous to pubescent with un branched or dendritically branched trichomes, and have tapered anthers with small terminal pores. Section Cyphomandropsis is closely related to Solanum sect. Pachyphylla (formerly genus Cyphomandra), from which it differs by lacking discrete, enlarged connectives on the abaxial anther surfaces.

PhytoKeys 8: 89–98. doi: 10.3897/phytokeys.8.2199 Abstract Solanum is one of the largest plant genera and exhibits a wide range of morphological diversity. Solanum section Gonatotrichum, the focus of this study, is unique within the genus because of its fruits that swell with turgor pressure and explosively dehisce to disperse the seeds. We infer phylogenetic relationships within section Gonatotrichum using DNA sequence data from two nuclear regions (ITS and the granule- bound starch synthase gene [GBSSI or waxy]) and the chloroplast region trnT-F. The resulting phyloge- netic trees support the monophyly of the section with the inclusion of S. lignescens, a species not previously thought to belong to the group due to the presence of stellate hairs. This inclusion of this species in sec- tion Gonatotrichum suggests that the simple, often geniculate hairs of species in the group may represent reduced stellate hairs.

  • Reproductive Characteristics As Drivers of Alien Plant Naturalization and Invasion
    Reproductive characteristics as drivers of alien plant naturalization and invasion Dissertation submitted for the degree of Doctor of Natural Sciences presented by Mialy Harindra Razanajatovo at the Faculty of Sciences Department of Biology Date of the oral examination: 12 February 2016 First referee: Prof. Dr. Mark van Kleunen Second referee: Prof. Dr. Markus Fischer Konstanzer Online-Publikations-System (KOPS) URL: http://nbn-resolving.de/urn:nbn:de:bsz:352-0-324483 Summary Due to human activity and global movements, many plant species have been introduced to non-native regions where they experience novel abiotic and biotic conditions. Some of these alien species manage to establish reproducing naturalized populations, and some naturalized alien species subsequently become invasive. Invasion by alien plant species can negatively affect native communities and ecosystems, but what gives the alien species an advantage under novel conditions is still not clear. Therefore, identifying the drivers of invasions has become a major goal in invasion ecology. Reproduction is crucial in plant invasions, because propagule supply is required for founding new populations, population maintenance and spread in non-native regions. Baker’s Law, referring to the superior advantage of species capable of uniparental reproduction in establishing after long distance dispersal, has received major interest in explaining plant invasions. However, previous findings regarding Baker’s Law are contradicting. Moreover, there has been an increasing interest in understanding the integration of alien plant species into native plant-pollinator networks but few studies have looked at the pollination ecology of successful (naturalized and invasive) and unsuccessful (non-naturalized and non-invasive) alien plant species.

  • Comparative Evidence for the Correlated Evolution of Polyploidy and Self-Compatibility in Solanaceae
    ORIGINAL ARTICLE doi:10.1111/j.1558-5646.2010.01099.x COMPARATIVE EVIDENCE FOR THE CORRELATED EVOLUTION OF POLYPLOIDY AND SELF-COMPATIBILITY IN SOLANACEAE Kelly Robertson,1,2 Emma E.

In plant families in which self-incompatibility is mediated by S-RNases, previous evidence suggests that polyploidy may often directly cause self-compatibility through the formation of diploid pollen grains. We use three approaches to examine relationships between self- incompatibility and ploidy. First, we test whether evolution of self-compatibility and polyploidy is correlated in the nightshade family (Solanaceae), and find the expected close association between polyploidy and self-compatibility. Second, we compare the rate of breakdown of self-incompatibility in the absence of polyploidy against the rate of breakdown that arises as a byproduct of polyploidization, and we find the former to be greater. Third, we apply a novel extension to these methods to show that the relative magnitudes of the macroevolutionary pathways leading to self-compatible polyploids are time dependent. Over small time intervals, the direct pathway from self-incompatible diploids is dominant, whereas the pathway through self-compatible diploids prevails over longer time scales. This pathway analysis is broadly applicable to models of character evolution in which sequential combinations of rates are compared.
