Journal ArticleDOI

Berendsohn,Thomas Borsch,Sabine von Mering,Hossein Akhani,Salvador Arias,Idelfonso Castañeda-Noa,Urs Eggli,Roger Eriksson,Hilda Flores-Olvera,Susy Fuentes-Bazan,Gudrun Kadereit,Cornelia Klak,Nadja Korotkova,Reto Nyffeler,Gilberto Ocampo,Helga Ochoterena,Bengt Oxelman,Richard K. Rabeler,Adriana Sanchez,Boris O. Schlumpberger,Pertti Uotila +21 more
TL;DR: A taxonomic backbone at the genus level is provided that reflects the current state of knowledge and accepts 749 genera for the Caryophyllales, a major lineage of flowering plants with approximately 12500 species in 39 families.
Journal ArticleDOI
Molecular phylogenetics of suborder Cactineae (Caryophyllales), including insights into photosynthetic diversification and historical biogeography.
TL;DR: Reconstruction of photosynthesis diversification showed C(3) to be the ancestral pathway, a shift to C(4) in Portulacaceae, and five independent origins of Crassulacean acid metabolism (CAM) showed Cactineae were inferred to have originated in the New World.
Journal ArticleDOI
Revealing diversity in structural and biochemical forms of C4 photosynthesis and a C3–C4 intermediate in genus Portulaca L. (Portulacaceae)
TL;DR: The results indicate that multiple structural and biochemical forms of C4 photosynthesis evolved in genus Portulaca.
Journal ArticleDOI
Molecular phylogenetics, historical biogeography, and chromosome number evolution of Portulaca (Portulacaceae).
TL;DR: The analyses strongly support the monophyly of Portulaca, with an age of the most recent common ancestor (MRCA) of 23 Myr and a number of chromosome number change events shown to have occurred in the genus, especially within the Oleracea clade.
Journal ArticleDOI
Evolution of leaf anatomy and photosynthetic pathways in Portulacaceae
Gilberto Ocampo,Nuria K. Koteyeva,Elena V. Voznesenskaya,Gerald E. Edwards,Tammy L. Sage,Rowan F. Sage,J. Travis Columbus +6 more
TL;DR: The diversity of leaf anatomical types and C4 biochemical variants suggest multiple independent origins of C4 photosynthesis, and evidence for a switch from C4 to C3-C4 intermediacy supports the hypothesis that intermediates represent a distinct successful strategy.
