Phylogeny and Evolution of the Cucurbitaceae

  title={Phylogeny and Evolution of the Cucurbitaceae},
  author={Susanne S. Renner and Hanno Schaefer},
The Cucurbitaceae family contains about 1000 species in 96 genera. [] Key Result The major phylogenetic structure of the family is now clear, and this chapter includes an up-to-date phylogenetic scheme with the placement of all genera. The Cucurbitaceae clade originated in mainland Southeast Asia sometime in the Late Cretaceous, and the five deepest evolutionary divergences in the family all date to the Late Cretaceous, 70–80 Ma.

The complete chloroplast genome sequences of the Sicyos angulatus (Cucurbitaceae)

A phylogenetic analysis of 64 CP genomes from Cucurbitaceae revealed that the Sicyos angulatus was separated from other species and clustered together with Sicyo edulis, which is congruent with previous studies.

Origin and domestication of Cucurbitaceae crops:insights from phylogenies, genomics and archaeology.

Insights on cucurbit domestication from new phylogenies, archaeology, and genomic studies are reviewed, suggesting that an annual life cycle may have contributed to domestication.

Comparative Chloroplast Genome Analysis of Wax Gourd (Benincasa hispida) with Three Benincaseae Species, Revealing Evolutionary Dynamic Patterns and Phylogenetic Implications

The de novo assembly and annotation of the complete chloroplast genome of wax gourd with 156,758 bp is reported, suggesting a difference in genome size, gene duplication and deletion, and the presence of pseudogenes.

Phylogenetic informativeness analyses to clarify past diversification processes in Cucurbitaceae

The potential of phylogenetic informativeness and tree confidence analyses to interpret phylogenomic datasets in Cucurbitaceae is explored, illustrating how formal analysis of phylogenomic data can increase the understanding of past diversification processes.

Karyotype stability and unbiased fractionation in the paleo-allotetraploid Cucurbita genomes

This study reports high-quality genome sequences of C. maxima and C. moschata and provides evidence supporting an allotetraploidization event in Cucurbita, and provides insights into plant genome evolution and valuable resources for genetic improvement of cucurbit crops.

Distribution and population characteristics of the Cucumber Tree (Dendrosicyos socotranus Balf.f.)

This study conducted a study throughout Socotra Island to investigate the distribution, population structure and regeneration potential of the endemic and threatened tree species Dendrosicyos socotranus, the Cucumber Tree, finding that 16% of the individual trees regenerated.

The Cytological Studies on Neglected and Underutilized Cucurbit Species with Special Reference to Chayote, an Under-Exploited Species

Agronomic and evolutionary importance based on cytological evidence in NUCuS, mainly in the prominent chayote are discussed, with the perspective to prompt breeding, conservation, cytology, structural and functional genomics research for its sustainable utilization.

A Comparative Account of Fluorescent Banding Pattern in the Karyotypes of Two Indian Luffa Species

This study provides a chromosomal dataset of the Indian Luffa germplasm that may be utilized for genome research and programmed breeding strategies, and the conservation of banding patterns between the species raises the possibility to revise genomic kin-ships and evolutionary distance.

Large-scale gene gains and losses molded the NLR defense arsenal during the Cucurbita evolution

Genome-wide annotation reveals that the gene birth–death process of the Cucurbita R family is associated with a species-specific diversification of TNL and CNL protein classes, and the maximum likelihood analyses revealed an unusual diversifying of CNL/TNL genes and a strong RNL conservation.

Cucurbit Genetics and Genomics: A Look to the Future

This volume explored the genetic diversity of cucur Bit crops, advances to unravel cucurbit genomes, and evolving applications of genomics to understand cucurbits growth, development and adaptation to their environments.



Phylogenetic relationships in the order Cucurbitales and a new classification of the gourd family (Cucurbitaceae)

This work recircumscribe tribes and genera within Cucurbitaceae and present a more natural classification for this family, comprising 95 genera in 15 tribes, five of them new: Actinostemmateae, Indofevilleeae, Thladiantheae, Momordiceae, and Siraitieae.

Austrobryonia (Cucurbitaceae), a New Australian Endemic Genus, is the Closest Living Relative to the Eurasian and Mediterranean Bryonia and Ecballium

A phylogenetic analysis of plastid and nuclear DNA sequences that includes all four species in a family-wide context revealed that Austrobryonia is the closest living relative to a Eurasian and Mediterranean clade consisting of Bryonia L. and Ecballium L.

Phylogenetics of Cucumis (Cucurbitaceae): Cucumber (C. sativus) belongs in an Asian/Australian clade far from melon (C. melo)

It is concluded that Cucumis comprises an old Australian/Asian component that was heretofore unsuspected and is phylogenetically far more distant from C. melo than implied by the current morphological classification.

Phylogeography of the ancient Eurasian medicinal plant genus Bryonia (Cucurbitaceae) inferred from nuclear and chloroplast sequences

P phylogenetic and phylogeographic analyses of chloroplast and nuclear sequences are used to infer the major evolutionary units within Bryonia as well as their geographic history.

Cucumis (Cucurbitaceae) in Australia and Eastern Malesia, Including Newly Recognized Species and the Sister Species to C. melo

Molecular phylogenetic analyses based on numerous plant accessions have shown that Cucumis comprises 25 species in Asia, the Malesian region, and Australia, rather than just two as traditionally thought, and four from tropical Australia are described.

Linnaeosicyos (Cucurbitaceae): a New Genus for Trichosanthes amara, the Caribbean Sister Species of all Sicyeae

This species from Hispaniola is placed in a new genus, Linnaeosicyos, described and illustrated, and its phylogenetic context is discussed using molecular and morphological data.

A Gift from the New World? The West African Crop Cucumeropsis mannii and the American Posadaea sphaerocarpa (Cucurbitaceae) are the Same Species

The near-absence of genetic and morphological differentiation implies that gene flow between Cucumeropsis manni and Posadaea sphaerocarpa stopped relatively recently, and taxonomically they should (or could) be treated as one species.
