Results show that key alterations of foliar anatomy occurring in a C3 context and preceding the emergence of the C4 syndrome by millions of years facilitated the repeated evolution of one of the most successful physiological innovations in angiosperm history.
PHYLOGENETICS OF ANDROPOGONEAE (POACEAE: PANICOIDEAE) BASED ON NUCLEAR RIBOSOMAL INTERNAL TRANSCRIBED SPACER AND CHLOROPLAST trnL-F SEQUENCES
Phylogenetic relationships among 85 species representing 35 genera in the grass tribe Andropogoneae were estimated from maximum parsimony and Bayesian analyses of nuclear ITS and chloroplast trnL-F…
Phylogenetics of Chloridoideae (Gramineae): a Preliminary Study Based on Nuclear Ribosomal Internal Transcribed Spacer and Chloroplast trnL–F Sequences
The phylogeny of Chloridoideae (Gramineae) was inferred from parsimony analyses of DNA sequences from two genomes, and suggested significant homoplasy in morphological traits, including inflorescence type, number of florets per spikelet, and number of lemma nerves.
Molecular phylogenetics of suborder Cactineae (Caryophyllales), including insights into photosynthetic diversification and historical biogeography.
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.
CLADISTIC PARSIMONY ANALYSIS OF INTERNAL TRANSCRIBED SPACER REGION (NRDNA)SEQUENCES OF BOUTELOUA AND RELATIVES (GRAMINEAE : CHLORIDOIDEAE)
The phylogeny of Boute/oua and relatives (Gramineae: Chloridoideae) employing cladistic parsimony analysis of nuclear ribosomal internal transcribed spacer region was estimated using PAUP and suggested homoplasy in morphological, anatomical, and breeding system traits.
Phylogenetic Relationships in Cariceae (Cyperaceae) Based on ITS (nrDNA) and trnT-L-F (cpDNA) Region Sequences: Assessment of Subgeneric and Sectional Relationships in Carex with Emphasis on Section…
A molecular phylogenetic study employing nrDNA ITS and cpDNA trnT-L-F spacer sequences assesses relationships within Carex section Acrocystis and identifies a monophyletic group for more detailed study, suggesting that Cymophyllus, Kobresia, Schoenoxiphium, and Uncinia are nested within carex.
Molecular phylogenetics, historical biogeography, and chromosome number evolution of Portulaca (Portulacaceae).
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.
Classification and Biogeography of New World Grasses: Chloridoideae
Subfamily Chloridoideae (Poaceae) in the New World includes 72 genera (61 native, 11 introduced), 678 species (607 native), and, including intraspecific taxa, 817 total taxa. The five largest genera…
A map of WW domain family interactions
The first protein‐protein interaction map of a domain in the human proteome is described, which allows for the rapid elucidation of WW domain‐ligand interactions with multiple applications including prediction of exact WW ligand binding sites, which can be applied to the mapping of other protein signaling domain families.
Proposal for an Expanded Distichlis (Poaceae, Chloridoideae): Support from Molecular, Morphological, And Anatomical Characters
The nuclear and chloroplast phylogenies indicate that Monanthochloë and Reederochloa are nested within a paraphyleticdistichlis, and a number of structural characters, including leaf blade length, number of spikelets per inflorescence, and number of florets per spikelet, also fall within the range of variation in Distichlis.
