Phylogenetic Relationships in the Order Cucurbitales and a New Classification of the Gourd Family (Cucurbitaceae)
Schaefer & Renner • Phylogenetic relationships in Cucurbitales TAXON 60 (1) • February 2011: 122–138 TAXONOMY Phylogenetic relationships in the order Cucurbitales and a new classification of the gourd family (Cucurbitaceae) Hanno Schaefer1 & Susanne S. Renner2 1 Harvard University, Department of Organismic and Evolutionary Biology, 22 Divinity Avenue, Cambridge, Massachusetts 02138, U.S.A. 2 University of Munich (LMU), Systematic Botany and Mycology, Menzinger Str. 67, 80638 Munich, Germany Author for correspondence: Hanno Schaefer, [email protected] Abstract We analysed phylogenetic relationships in the order Cucurbitales using 14 DNA regions from the three plant genomes: the mitochondrial nad1 b/c intron and matR gene, the nuclear ribosomal 18S, ITS1-5.8S-ITS2, and 28S genes, and the plastid rbcL, matK, ndhF, atpB, trnL, trnL-trnF, rpl20-rps12, trnS-trnG and trnH-psbA genes, spacers, and introns. The dataset includes 664 ingroup species, representating all but two genera and over 25% of the ca. 2600 species in the order. Maximum likelihood analyses yielded mostly congruent topologies for the datasets from the three genomes. Relationships among the eight families of Cucurbitales were: (Apodanthaceae, Anisophylleaceae, (Cucurbitaceae, ((Coriariaceae, Corynocarpaceae), (Tetramelaceae, (Datiscaceae, Begoniaceae))))). Based on these molecular data and morphological data from the literature, we recircumscribe tribes and genera within Cucurbitaceae and present a more natural classification for this family. Our new system comprises 95 genera in 15 tribes, five of them new: Actinostemmateae, Indofevilleeae, Thladiantheae, Momordiceae, and Siraitieae. Formal naming requires 44 new combinations and two new names in Cucurbitaceae. Keywords Cucurbitoideae; Fevilleoideae; nomenclature; nuclear ribosomal ITS; systematics; tribal classification Supplementary Material Figures S1–S5 are available in the free Electronic Supplement to the online version of this article (http://www.ingentaconnect.com/content/iapt/tax). -

Trichosanthes (Cucurbitaceae) Hugo J De Boer1*, Hanno Schaefer2, Mats Thulin3 and Susanne S Renner4
de Boer et al. BMC Evolutionary Biology 2012, 12:108 http://www.biomedcentral.com/1471-2148/12/108 RESEARCH ARTICLE Open Access Evolution and loss of long-fringed petals: a case study using a dated phylogeny of the snake gourds, Trichosanthes (Cucurbitaceae) Hugo J de Boer1*, Hanno Schaefer2, Mats Thulin3 and Susanne S Renner4 Abstract Background: The Cucurbitaceae genus Trichosanthes comprises 90–100 species that occur from India to Japan and southeast to Australia and Fiji. Most species have large white or pale yellow petals with conspicuously fringed margins, the fringes sometimes several cm long. Pollination is usually by hawkmoths. Previous molecular data for a small number of species suggested that a monophyletic Trichosanthes might include the Asian genera Gymnopetalum (four species, lacking long petal fringes) and Hodgsonia (two species with petals fringed). Here we test these groups’ relationships using a species sampling of c. 60% and 4759 nucleotides of nuclear and plastid DNA. To infer the time and direction of the geographic expansion of the Trichosanthes clade we employ molecular clock dating and statistical biogeographic reconstruction, and we also address the gain or loss of petal fringes. Results: Trichosanthes is monophyletic as long as it includes Gymnopetalum, which itself is polyphyletic. The closest relative of Trichosanthes appears to be the sponge gourds, Luffa, while Hodgsonia is more distantly related. Of six morphology-based sections in Trichosanthes with more than one species, three are supported by the molecular results; two new sections appear warranted. Molecular dating and biogeographic analyses suggest an Oligocene origin of Trichosanthes in Eurasia or East Asia, followed by diversification and spread throughout the Malesian biogeographic region and into the Australian continent. -

Morphology and Embryology of <Emphasis Type="Italic">Marah
MORPHOLOGY AND EMBRYOLOGY OF MARAH MACROCARPA GREENE BY A. S. R. DATHAN AND DALBIR SINGH (Department of Botany, University of Rajasthan, Jaipur) Received March, 20, 1970 (Communicated by Prof. K. S. Thind, r.h.sc.) ABSTRACT The ovary is usually tricarpeUary, rarely bicarFellary and covered with spines and glav.dular and eglandular hairs in Marah macrocarpa Greene. Structure and develotzment of spines m~.d two tylces of hairs are described. Ovules are anatropous, bitegmic ar.d crassi~ucellate. The ovular bundle"' ramifies after fertilization. Develo]cment of embryo- sac is of Polygonum tylce. The pollma-tube is rersistent and sometimes dilates at the base of the nr.cellar beak. The er.dosFerm is Nuclear and enucleate cytoplasmic r.odules are formed. The wall formatien is pro- gressive and chalazal endosperm haustorit:m is short and coenocytic. Rarely, it is rudimentary. Embroyogeny is suggestive of Onagrad tyl~e. Hemitriand hemitetracotyledonary embryos are also recorded. The seed.coat develops from the outer integument alone. The mature seedcoat comprises seed epidermis, hypodermis, main scleren- chymatous layer of narrow osteosclereids, (all derived from the outer epidermis of outer integument) aerenchyma and chlorenchyma. INTRODUCTION Marah Kellogg is a North American genus of the tribe Cyclanthereae of Cucurbitaceao. It includes seven species (Willis, 1966)and provides a rare example of numerical polyploidy in this family. Whitaker (1950) described that the plants of Marah macroca~Ta Greene (Syn. Echinocystis macrocarpa Greene) sampled in San Diego county, California, are tetraploid. M. macro- carpa, commonly called Chiliclothe or mock cucumber, has a large under- ground tuberous system and large spiny fruits dehiscent at the tip. -
Distribution and Ecology Nomenclature What Are
1 WHAT ARE CUCURBITS? DISTRIBUTION AND ECOLOGY The Cucurbitaceae is a family of frost-sensitive and predominantly tendril- bearing vining plants that are found in subtropical and tropical regions around the globe. There are only a few species that are native to temperate climates; they are either prolific seed-producing annuals, perennials that live for one season until killed by frost, or xerophytic perennials whose succulent under- ground parts survive the winter. Ecologically, the family is dichotomous; many genera flourish in the humid tropics, particularly in southeastern Asia and the neotropics, whereas other genera are native to the arid regions of Africa, Madagascar and North America. Members of the latter group, the xerophytes, usually have large perennial roots and succulent stems that are clambering and creeping and at least partially subterranean; in some cases, tendrils or leaves are lacking or greatly modified. Although most crops in the Cucurbitaceae have been selected from the mesophytic annuals, concern over famine and fuel sources in arid countries has led to interest in turning some of the xerophytes into agricultural crops. NOMENCLATURE ‘Cucurbits’ is a term coined by Liberty Hyde Bailey for cultivated species of the family Cucurbitaceae. Beginning in the early 20th century, the term has been used not only for cultivated forms, but also for any species of the Cucurbitaceae, and it will be so used in this book. Other vernaculars applied to the family and various of its members are ‘gourd’, ‘melon’, ‘cucumber’, ‘squash’ and ‘pumpkin’. Of these, squash and pumpkin are the most straightforward, almost always referring to species of Cucurbita. -
Phylogeny of the Cucurbitales Based on DNA Sequences of Nine Loci from Three Genomes: Implications for Morphological and Sexual System Evolution
Molecular Phylogenetics and Evolution 39 (2006) 305–322 www.elsevier.com/locate/ympev Phylogeny of the Cucurbitales based on DNA sequences of nine loci from three genomes: Implications for morphological and sexual system evolution Li-Bing Zhang a,*, Mark P. Simmons a, Alexander Kocyan b, Susanne S. Renner b a Department of Biology, Colorado State University, Fort Collins, CO 80523, USA b Department of Biology, Ludwig Maximilians University, Menzinger-Str. 67, D-80638 Munich, Germany Received 1 July 2005; revised 30 September 2005; accepted 1 October 2005 Available online 15 November 2005 Abstract The Cucurbitales are a clade of rosids with a worldwide distribution and a striking heterogeneity in species diversity among its seven family members: the Anisophylleaceae (29–40 species), Begoniaceae (1400 spp.), Coriariaceae (15 spp.), Corynocarpaceae (6 spp.), Cucurbitaceae (800 spp.), Datiscaceae (2 spp.), and Tetramelaceae (2 spp.). Most Cucurbitales have unisexual flowers, and species are monoecious, dioecious, andromonoecious, or androdioecious. To resolve interfamilial relationships within the order and to polarize morphological character evolution, especially of flower sexual systems, we sequenced nine plastids (atpB, matK, ndhF, rbcL, the trnL- F region, and the rpl20–rps12 spacer), nuclear (18S and 26S rDNA), and mitochondrial (nad1 b/c intron) genes (together 12,000 bp) of 26 representatives of the seven families plus eight outgroup taxa from six other orders of the Eurosids I. Cucurbitales are strongly supported as monophyletic and are closest to Fagales, albeit with moderate support; both together are sister to Rosales. The deepest split in the Cucurbitales is that between the Anisophylleaceae and the remaining families; next is a clade of Corynocarpaceae and Coriariaceae, followed by Cucurbitaceae, which are sister to a clade of Begoniaceae, Datiscaceae, and Tetramelaceae.
