“…We used information on sexual system and the presence of ray flowers from 13 publications (Anderberg, 1982, 1985, 1991a, b, 1995; Keighery, 1984; Wiklund, 1985; Halvorsen and Borgen, 1986; Bremer, 1994; Hind, 1996; Duman and Anderberg, 1999; Aytac and Anderberg, 2001; Anderberg and Eldenäs, 2007). To explore the transitions between sexual systems, we modeled changes in sexual system by means of the stochastic character mapping technique (Huelsenbeck et al, 2003), implemented in the program SIMMAP 1.0 beta 2.3.2 (Bollback, 2006).…”

From an ancestor with bisexual flowers, plants with unisexual flowers, or even unisexual individuals have evolved in different lineages of angiosperms. The Asteraceae tribe Inuleae includes hermaphroditic, monoecious, dioecious, and gynomonoecious species. Gynomonoecy, the sexual system in which female and bisexual flowers occur on the same plant, is prevalent in the Asteraceae. We inferred one large gene phylogeny (ndhF) and two supertrees to investigate whether gynomonoecy was a stage in the evolution from hermaphroditism to monoecy. We identified transitions in sexual system evolution using the stochastic character mapping method. From gynomonoecious ancestors, both hermaphroditic and monoecious descendants have evolved. Gynomonoecy was not restricted to a stage in the evolution toward monoecy because the number of transitions and the rate of change from monoecy to gynomonoecy were much higher than the opposite. We also investigated one hypothesized association among female flowers and the development of a petaloid ray as an explanation of gynomonoecy maintenance in Asteraceae. We found that peripheral female flowers and petaloid rays were phylogenetically correlated. However, empirical evidence shows that a causal relationship between these traits is not clear.

“…Within Inulinae, both these character states are homoplasious and should be considered unreliable, or at least insufficient, in a generic diagnosis. C. dichotomum and C. gueneri are endemic to Turkey and in the ndhF tree they group with the epaleate Pentanema alanyense Duman & Anderb., another endemic from the same region that grows together with C. gueneri (Aytac and Anderberg, 2001) (the problematic genus Pentanema is discussed below). The third species, the generic type C. montanum , has a more eastern distribution extending into Syria and Iraq.…”

Phylogenetic relationships and generic delimitation in Inuleae subtribe Inulinae (Asteraceae) based on ITS and cpDNA sequence data

Phylogenetic relationships in Inuleae subtribe Inulinae (Asteraceae) were investigated. DNA sequence data from three chloroplast regions (ndhF, trnL-F and psbA-trnH) and the nuclear ribosomal internal transcribed spacer (ITS) region were analysed separately and in combination using parsimony and Bayesian inference. A total of 163 ingroup taxa were included, of which 60 were sampled for all four markers. Conflicts between chloroplast and nuclear data were assessed using partitioned Bremer support (PBS). Rather than averaging PBS over several trees from constrained searches, individual trees were considered by evaluating PBS ranges. Criteria to be used in the detection of a significant conflict between data partitions are proposed.

“…Till today, only a few studies on morphological characteristics of the genus Chrysophthalmum, and preliminary evaluation of its biological activities, including antioxidant, and antimicrobial activities, as well as only one phytochemical research on C. montanum have been reported [2,[7][8][9][10]. In our previous study, the bioassay-guided isolation, and identification of the cytotoxic compounds of the aerial parts of C. montanum were carried out [11].…”

The aerial parts of Chrysophthalmum montanum (DC.) Boiss. (Asteraceae) is traditionally used for wound healing, as well as for the treatment of common cold, sinusitis, and other inflammatory diseases. The objectives of this study were to identify potential anti-inflammatory effects of the methanol extract, and its different polarity subextracts (n-hexane, chloroform, n-butanol, and remaining aqueous), and guaianolide-type sesquiterpene lactones [6α-acetoxy-4α-hydroxy-1βH-guaia-9.11(13)-dien-12.8α-olide (1), 6α-acetoxy-4αhydroxy-9β.10β-epoxy-1βH-guaia-11(13)-en-12.8α-olide (2), 4α,6α-dihydroxy-1β,5α,7αH-guaia-9(10),11(13)dien-12,8α-olide (3), and (4α,5α,8β,10β)-4,10-dihydroxy-1,11(13)-guaidien-12,8-olide (4)] from the aerial parts of C. montanum. In order to evaluate the anti-inflammatory activity of C. montanum, carrageenan-and PGE2induced hind paw edema, and acetic acid-induced increase in capillary permeability mice models were used. The methanol extract, the chloroform subextract, and compounds 3, and 4 were shown to possess anti-inflammatory activity in in vivo models at 100 mg/kg dose. The results provide a biological, and phytochemical basis for the traditional use of C. montanum aerial parts for inflammatory conditions in Turkish folk medicine.
