“…The highest-scoring ML tree obtained for the 260-taxon dataset (figure 1) shows Cucurbitaceae highly supported as monophyletic and family relationships similar to those found by Zhang et al (2006) with a much larger amount of sequence data. Within Cucurbitaceae, there are five main clades (figure 1), namely: (i) a group of approximately 100 genera traditionally treated as subfamily Cucurbitoideae (Kosteletzky 1833) and usually subdivided into several tribes (below); (ii) a clade of Asian genera, including Alsomitra, Bayabusua and Neoalsomitra that corresponds to the tribe Gomphogyneae of Bentham & Hooker (1867); (iii) a clade of one African and five Neotropical genera, including Fevillea and Sicydium, that corresponds to the tribe Fevilleeae of Bentham & Hooker (1867); (iv) a clade of a few genera from Madagascar, continental Africa, Asia and South America corresponding to the tribe Zanonieae of Blume (1826); and (v) a clade consisting of the two Asian genera Actinostemma and Bolbostemma.…”

“…GenBank accession numbers (EU436320-EU436422) and vouchers for newly sequenced taxa are listed in table 1 in the electronic supplementary material. Accession numbers and voucher information for additional Cucurbitaceae sequences from our earlier studies are given in Zhang et al (2006), Kocyan et al (2007), Schaefer et al (2008a) and Nee et al (submitted). Fourteen sequences from Genbank were included to represent Indomelothria (EF065456), Neoachmandra (EF065484-86), Urceodiscus (EF065464) and Zehneria ( EF065485, EF065489, EF065491-493, EF065497, EF065499-500 and EF065502).…”

“…Judging from morphology, it is expected to group with other Asian Benincaseae. As outgroups, we used 15 species of the Cucurbitales families Anisophyllaceae, Begoniaceae, Coriariaceae, Corynocarpaceae, Datiscaceae and Tetramelaceae, based on Zhang et al (2006). Of these, the Begoniaceae, Datiscaceae and Tetramelaceae, with the Cucurbitaceae, constitute a morphologically and molecularly well-defined clade, traditionally called the core Cucurbitales (Zhang et al 2006).…”

Knowing the geographical origin of economically important plants is important for genetic improvement and conservation, but has been slowed by uneven geographical sampling where relatives occur in remote areas of difficult access. Less biased species sampling can be achieved when herbarium collections are included as DNA sources. Here, we address the history of Cucurbitaceae, one of the most economically important families of plants, using a multigene phylogeny for 114 of the 115 genera and 25 per cent of the 960 species. Worldwide sampling was achieved by using specimens from 30 herbaria. Results reveal an Asian origin of Cucurbitaceae in the Late Cretaceous, followed by the repeated spread of lineages into the African, American and Australian continents via transoceanic long-distance dispersal (LDD). North American cucurbits stem from at least seven range expansions of Central and South American lineages; Madagascar was colonized 13 times, always from Africa; Australia was reached 12 times, apparently always from Southeast Asia. Overall, Cucurbitaceae underwent at least 43 successful LDD events over the past 60 Myr, which would translate into an average of seven LDDs every 10 Myr. These and similar findings from other angiosperms stress the need for an increased tapping of museum collections to achieve extensive geographical sampling in plant phylogenetics.

“…The closest outgroups of the Cucurbitaceae, united in a trichotomy, are the Begoniaceae + Datiscaceae + Tetramelaceae and Coriariaceae + Corynocarpaceae (Zhang et al, 2006;Angiosperm Phylogeny Group, 2009;). Striate pollen occurs in the Begoniaceae and the perforaterugulate type of Alsomitra (basal in Gomphogyneae) reminds of the perforate-verrucate pollen of the Datiscaceae and the perforate-psilate pollen of the Tetramelaceae ( Van den Berg, 1985).…”

Correns ' s 1903 ( Berichte der Deutschen Botanischen Gesellschaft 21: 133 -147) crosses between a monoecious and a dioecious species of Bryonia revealed the simple Mendelian inheritance of dioecy and provided the fi rst instance of an XY sex determination system in any organism. Bryonia ranges from the Canary Islands to Central Asia and comprises seven dioecious and three monoecious species; its closest relative, Ecballium elaterium , has dioecious and monoecious populations. We used chloroplast (cp) and nuclear (nr) gene phylogenies to infer sexual system evolution in Bryonia . We also tested for associations between sexual system and ploidy level, based on published and original chromosome counts. Confl icts between cp and nr topologies imply that the dioecious hexaploid B. cretica arose from hybridization(s), probably involving the dioecious diploids B. dioica , B. syriaca , and/or B. multifl ora . A tetraploid dioecious endemic on Corsica and Sardinia probably originated from B. dioica via autopolyploidy. While the cp phylogeny resolves few species relationships, the nr tree implies at least two evolutionary changes in sexual system. There is no correlation between sexual system and ploidy level. Molecular clocks suggest that the deepest divergence, between a species on the Canary Islands and the ancestor of all remaining species, occurred ca. 10 million years ago.
