“…The subtribe Plucheinae was supported as a sister group to Inulinae (PP = 0.98; Fig. F), as in most previous studies (Anderberg, , ; Englund et al, ; Nylinder & Anderberg, ). Within Plucheinae, the Chinese Pseudoconyza was resolved as sister to the rest of Sphaeranthus , Laggera , Pluchea , Karelinia , and Epaltes with strong support (PP = 0.98; BS = 96; Fig.…”

The sunflower family (Asteraceae) is the largest and the most diverse flowering plant family, comprising 24 000-30 000 species and 1600-1700 genera. In China, Asteraceae are also the largest family, with approximately 2336 indigenous species in 248 genera. In the past two decades, molecular phylogenetic analyses has contributed greatly to our understanding of the systematics of Asteraceae. Nevertheless, the large-scale analyses and knowledge about the relationships of Chinese Asteraceae at the generic level as a whole are far from complete due to difficulties in sampling. In this study, we presented a three-marker (rbcL, ndhF, and matK) phylogeny of Asteraceae, including 506 genera (i.e., approximately one-third of Asteraceae genera). The study sampled 200 Chinese genera (i.e., approximately 80% of Chinese Asteraceae genera). The backbones of the new phylogeny were largely congruent with earlier studies, with 13 subfamilies and 45 tribes recognized. Chinese Asteraceae were distributed in 7 subfamilies (Mutisioideae, Wunderlichioideae, Carduoideae, Pertyoideae, Gymnarrhenoideae, Cichorioideae, and Asteroideae) and 22 tribes (Mutiseae, Hyalideae, Cardueae, Pertyeae, Gymnarrheneae, Vernonieae, Cichorieae, Doroniceae, Senecioneae, Astereae, Anthemideae, Gnaphalieae, Calenduleae, Inuleae, Athroismeae, Helenieae, Coreopsideae, Neurolaeneae, Tageteae, Millieae, Eupatorieae, and Heliantheae). Chinese Asteraceae lacked 6 basal subfamilies and 23 tribes. Several previously ambiguous relationships were clarified. Our analyses also resolved some unplaced genera within Chinese Asteraceae. Finally, our phylogenetic tree was used to revise the classification for all genera of Chinese Asteraceae. In total, 255 genera, 22 tribes, and 7 subfamilies in China are recognized.

IntroductionHeartleaf oxeye [Telekia speciosa (Schreb.) Baumg., Asteraceae, tribe Inuleae, basionym -Buphtalmum speciosum Schreb.] is a perennial plant native to Southeastern Europe and Asia Minor. It is the only species belonging to the genus Telekia Baumg. [1], which, accordingly to recent molecular phylogenetic studies based on both cpDNA and ITS sequence analysis [2] is closely related to Carpesium spp. and a group of resiniferous taxa of Inula L., including Inula helenium -a well known medicinal plant. Likewise the roots of the resiniferous Inula species, roots of T. speciosa contain essential oil with eudesmane-type sesquiterpene lactones as major constituents. Except for sesquiterpene lactones of eudesmanolide and pseudoguaianolide type, the plant reportedly contains xanthanolides, terpenoid cyclopropenone derivatives, polyacetylene, thymol and nerol derivatives [3][4][5][6]. Data on medicinal uses of T. speciosa are sparse, however, biological activity of secondary metabolites produced by the plant have gained some interest. Except for widely investigated alantolactone and isoalantolactone, other sesquiterpene lactones -telekin and 2,3-dihydroaromaticin have also shown marked antiproliferative activity against human cancer cell lines in vitro [7,8]. Moreover, 2,3-dihydroaromaticin is a potent inhibitor of lipopolisaccharide induced nitric oxide synthesis and a moderate inhibitor of the transcription factor NF-κB activation [9,10].Telekin affected activity of some antioxidant and drug-metabolizing enzymes in rat liver and kidney [11,12]. In a recently published report on antiproliferative and direct cytotoxic activity of extracts from T. speciosa an interference of these preparations with cell proliferation in vitro has been proven [13].The aim of the present study was to achieve in vitro multiplication of T. speciosa shoots and to investigate secondary metabolism of the culture as a potential source of biologically active compounds. Material and methods Plant materialSeeds of Telekia speciosa (Schreb.) Baumg. were delivered by Botanical Garden in Nantes (France). Multiple shoots of the plant were collected from in vitro cultures maintained in our laboratory. As a reference material, aerial parts of Telekia speciosa (Schreb.) were harvested in July-August from plants grown in the Garden of Medicinal Plants, Institute of Pharmacology, Polish Academy of Sciences, Kraków, where a voucher specimen (10/08) was deposited. The plants were obtained by acclimatization of in vitro regenerated plantlets and were collected in the second year of their vegetation outside. AbstractMultiple shoots of Telekia speciosa were cultivated on MS medium containing 4.44 µM BAP and 0.54 µM NAA, solidified with agar. After eight weeks of culture the shoots were harvested and extracted with methanol. From the methanol extract one pseudoguaianolide -2,3-dihydroaromaticin and three thymol derivatives: 8-hydroxy-9,10-diisobutyryloxythymol, 10-isobutyryloxy-8,9-epoxythymyl isobutyrate and 10-(2-methylbutyryloxy)-8,9-epoxythymyl isobuty...

“…(Guti errez-Larruscain et al, 2018) has led all species of Inula L. distributed in the western Mediterranean area Àexcept for Inula helenium L.À to be transferred to Pentanema. These nomenclatural changes were meant to reflect the natural limits of both genera, which were considered to be "two hodgepodges" (Duman & Anderberg, 1999) and paraphyletic in their previous circumscription (Anderberg, 1991;Anderberg et al, 2005;Englund et al, 2009;Nylinder & Anderberg, 2015;Guti errez-Larruscain et al, 2018). The new circumscription of the genus Pentanema, described from Middle Eastern material includes approximately 40 species distributed throughout Asia, Africa, and Europe, 12 of which occupy the western Mediterranean area.…”

Forty‐five populations of Pentanema corresponding to seven species included in the Pentanema conyzae clade have been studied using AFLP fingerprinting. The results show that allopolyploidization could have been involved in the diversification of this group, specifically in species P. langeanum and P. maletii. Molecular data confirm the presence of P. britannicum in the Iberian Peninsula and key steps are provided to identify the species that are morphologically the most challenging.
