... For CCH Clade, allopolyploidy can be ruled out due to the diploidy of Caraganeae, Chesneyeae and Hedysareae (x = 8, rarely x = 7; Nie et al., 2002;Yang, 2002;Sepet et al., 2011), and no polyploidy event has been known to occur in these tribes. Regarding GAW Clade, several polyploid genera have been detected in Wisterieae (i.e., Callerya: 2n = 4x = 32 or Wisteriopsis: 2n = 6x = 48; Yeh et al., 1986), while other genera, such as Wisteria are diploid (2n = 16; IPCN, http://legacy.tropicos.org/Projec ...
The inverted repeat-lacking clade (IRLC) is one of the most derived clades within the subfamily Papilionoideae of the legume family, and includes various economically important plants, e.g., chickpeas, peas, liquorice, and the largest genus of angiosperms, Astragalus. Tribe Wisterieae is one of the earliest diverged groups of the IRLC, and its generic delimitation and spatiotemporal diversification need further clarifications. Based on genome skimming data, we herein reconstruct the phylogenomic framework of the IRLC, and infer the inter-generic relationships and historical biogeography of Wisterieae. We redefine tribe Caraganeae to contain Caragana only, and tribe Astragaleae is reduced to the Erophaca-Astragalean clade. The chloroplast capture scenario was hypothesized as the most plausible explanation of the topological incongruences between the chloroplast CDSs and nuclear ribosomal DNA trees in both the Glycyrrhizinae-Adinobotrys-Wisterieae clade and the Chesneyeae-Caraganeae-Hedysareae clade. A new name, Caragana lidou L.Duan & Z.Y.Chang, is proposed within Caraganeae. Thirteen genera are herein supported within Wisterieae, including a new genus, Villosocallerya L.Duan, J.Compton & Schrire, segregated from Callerya. Our biogeographic analyses suggest that Wisterieae originated in the late Eocene and its most recent common ancestor (MRCA) was distributed in continental southeastern Asia. Lineages of Wisterieae remained in the ancestral area from the early Oligocene to the early Miocene. By the middle Miocene, Whitfordiodendron and the MRCA of Callerya-Kanburia-Villosocallerya Clade became disjunct between the Sunda area and continental southeastern Asia, respectively; the MRCA of Wisteria migrated to North America via the Bering land bridge. The ancestor of Austrocallerya and Padbruggea migrated to the Wallacea-Oceania area, which split in the early Pliocene. In the Pleistocene, Wisteria brachybotrys, W. floribunda and Wisteriopsis japonica reached Japan, and Callerya cinerea dispersed to South Asia. This study provides a solid tribal-level phylogenetic framework for further evolutionary/biogeographic/systematic investigations on the ecologically diverse and economically important IRLC legumes.

The karyological analyses of 11 species, one taxon of which is endemic of Oxytropis (Fabaceae), distributed in Turkey were examined in this study. Among these taxa, the chromosome numbers were as follows: 2n = 16 in Oxytropis kotschyana, O. pallasii, O. pilosa, O. savellanica, O. persica, O. albana, O. argyroleuca, O. aucheri, O. karjaginii, O. lupinoides; and 2n = 96 in O. lazica. The karyotype analysis of taxa belonging to the genus Oxytropis was performed using Image Analysis System (Bs200Pro).
... Cytological information available to date suggests that all members of the studied group share the same base chromosome numbers of n = 7 or 8 although with varying levels of polyploidy levels (Ali 1959;Moore 1968;Mesicek & Sojak 1969;Maassoumi 1989;Takhtajan 1990;Khatoon & Ali 1991;Jahan et al. 1994;Barat 1996;Sifeng et al. 1998;Yang 2002;Abou-el-Enain 2002;Hosgoren 2006;Bader & Sherif 2007;Ranjbar et al. 2003;Sepet et al. 2011;Arsalan et al. 2010;.

A new subtribal classification of the Fabaceae-Caraganeae is presented informed by phylogenetic reconstruction using the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA (nr DNA) for 17 genera belonging to tribes Caraganeae, Galegeae and Astragaleae. Based on these results we propose to erect a new subtribe Chesneyinae Ranjbar, F. Hajmoradi and Waycott including Chesneya Lindl. ex Endl. and Guelden-staedtia Fisch. and revise the membership of subtribe Caraganinae as comprising Caragana Fabr., Calophaca Fisch. and Halimodendron Fisch. ex DC. Subtribe Caraganinae is characterised by the shrub habit and paripinnate leaves whereas the herbaceous habit and imparipinnate leaves are characteristic of subtribe Chesneyinae.

... These 3 genera are those resulting sister groups to the rest of Hedysareae after our phylogenetic analysis (Figure 2). Astragalus and Chesneya of the related Astragalean clade (Sepet et al., 2011) also have a basic number of n = 8. A count of 2n = 18 in Sulla coronaria (as Hedysarum coronarium) is known (Issolah et al., 2006), such that Arslan et al.

Results about a phylogenetic analysis of the genus Onobrychis Mill., tribe Hedysareae DC. are presented. The systematic knowledge of tribe Hedysareae is still incomplete, with difficult circumscription of genera and species. Analyses were undertaken using both nuclear (ITS) and chloroplast (matK) markers for a set of 78 accessions covering 41 Onobrychis species, besides previously sequenced Hedysareae accessions. The phylogenetic methods used were maximum parsimony, maximum likelihood, and Bayesian analyses to produce phylogenetic trees and robustness indices. The genus Onobrychis was resolved as paraphyletic, with species of the genera Eversmannia Bunge and Hedysarum L. nested within it. The position of the section Membranacea of genus Hedysarum was as a sister group to Onobrychis and Eversmannia, separated from other accessions of Hedysarum. Variation in the 2 markers was sufficient to resolve infrageneric groups in Onobrychis and Hedysarum, but we were unable to completely resolve certain species in Onobrychis, particularly those within the sect. Onobrychis. The cause of this difficult species delimitation may be related to recent speciation, hybridization, and introgression events, particularly between cultivated species and their wild relatives, and the presence of cryptospecies as suggested by intraspecific polyploid series.
Synthesized new unsymmetrical N-(pyridine-2-yl)pyrazin-2-amine (Hppza) ligand, its corresponding linear trinickel complexes and 1D zigzag chain copper(II) coordination polymer. All of these compounds were structurally characterized. Structure of Ni3(µ3-ppza)4Cl2 (1) or Ni3(µ3-ppza)4(NCS)2 (2) is similar to those of [Ni3(µ3-dpa)4X2] (where X = Cl-, NCS- and dpa- is a anion of unmodulated Hdpa ligand), showing an EMAC structure with four deprotonated supporting ppza- wrapped around the linear metal chain in a syn–syn form. The molecules are linear with Ni–Ni–Ni bond angles in the range of 178–179o and chloride or nitrogen atoms of axial ligands bonded to the terminal metal collinear with the Ni3 axis.
Here we report for the first time the synthèses of N2 (pyrazin-2-yl)-N7-(2-(pyrazin-2-ylamino)-1,8-naphthyridin-7-yl)-1,8-naphthyridine-2,7-diamine (N9-2pz) (1) and its linear octanuclear nickel string complex (2). The ligand N9-2pz was synthesized by the palladium-catalyzed cross-coupling of 2-aminopyrazine and bis(2-chloro-1,8-naphthyridine-7-yl)amine in the presence of catalysts [Pd2(dba)3, BINAP, ButONa] in refluxing toluene under argon and characterized by Elemental Analyses, IR, 1H NMR and MS(FAB).
Based on sequence data of nuclear ITS and plastid matK, trnL-F and psbA-trnH markers, the phylogeny of the subtribes Caraganinae and Chesneyinae in tribe Caraganeae was inferred. The results support the monophyly of each of the subtribes. Within subtribes Caraganinae, Calophaca and Halimodendron are herein transferred into Caragana to ensure its generic monophyly. The subtribe Chesneyinae is composed of four well-supported genera: Chesneya, Chesniella, Gueldenstaedtia and Tibetia. Based on phylogenetic, morphological, distributional and habitat type evidence, the genus Chesneya was divided into three monophyletic sections: C. sect. Chesneya, C. sect. Pulvinatae and C. sect. Spinosae. Chesneya macrantha is herein transferred into Chesniella. Spongiocarpella is polyphyletic and its generic rank is not maintained. The position of Chesneya was incongruent in the nuclear ITS and the plastid trees. A paternal chloroplast capture event via introgression is hypothesized for the origin of Chesneya, which is postulated to have involved the common ancestor of Chesniella (♂) and that of the Gueldenstaedtia - Tibetia (GUT) clade (♀) as the parents.
