A phylogenetic analysis of Chenopodiaceae and Amaranthaceae was carried out using sequence variation of the chloroplast gene rbcL. Our sampling included 108 species of these two families along with 29 species of Caryophyllales serving as outgroups. Phylogeny inferences with maximum parsimony and maximum likelihood indicate that the two families form a well‐supported monophyletic clade that is sister to Achatocarpaceae. Despite extensive sampling, we found that the relationship between… 
Phylogenetic analysis of the Australian Salicornioideae (Chenopodiaceae) based on morphology and nuclear DNA
The current tribal classification of the Salicornioideae was not supported in the molecular analysis and three major clades received strong bootstrap support: Microcnemum+Arthrocnemum, Sarcocornia+Salicornia, and the endemic Australian genera.
trnL-F and rpl16 Sequence Data and Dense Taxon Sampling Reveal Monophyly of Unilocular Anthered Gomphrenoideae (Amaranthaceae) and an Improved Picture of Their Internal Relationships
Parsimony and Bayesian analyses of trnL-F and rpl16 sequence data show that the subfamily Gomphrenoideae is monophyletic, which represents a large and diverse radiation of the Amaranthaceae in the New World.
Monophyly and infrageneric variation of Corispermum L. (Chenopodiaceae), evidence from sequence data psbB-psbH, rbcL and ITS
The phylogenetic trees confirm that the tribe Corispermeae is monophyletic, Corispermum and Agriophyllum have a close relationship, and the evolution of morphological characters for fruit wing and apex is consistent with the sectional division of Cor ispermum, especially to the East Asian and Chinese taxa.
Towards a species level tree of the globally diverse genus Chenopodium (Chenopodiaceae).
Molecular phylogeny of Atripliceae (Chenopodioideae, Chenopodiaceae): Implications for systematics, biogeography, flower and fruit evolution, and the origin of C4 photosynthesis.
UNLABELLED PREMISE OF THE STUDY Atripliceae (Chenopodiaceae), including Atriplex (300 spp.) as the largest genus of the family, are an ecologically important group of steppes and semideserts
Phylogeny of Tidestromia (Amaranthaceae, Gomphrenoideae) Based on Morphology
Traditional morphological evidence is important for circumscribing the genus Tidestromia, but shows limited utility for resolving species groups within this genus.
Phylogenetic Relationships in the Salicornioideae / Suaedoideae / Salsoloideae s.l. (Chenopodiaceae) Clade and a Clarification of the Phylogenetic Position of Bienertia and Alexandra Using Multiple DNA Sequence Datasets
This study focused on the relationships of the main lineages within this clade with an emphasis on the placement of the single cell functioning C4 genus Bienertia using maximum parsimony, maximum likelihood, and Bayesian inference phylogenetic analyses of the nuclear ribosomal ITS and five chloroplast DNA regions.
Fruit and Seed Anatomy of Chenopodium and Related Genera (Chenopodioideae, Chenopodiaceae/Amaranthaceae): Implications for Evolution and Taxonomy
A comparative carpological study of 96 species of all clades formerly considered as the tribe Chenopodieae has been conducted for the first time. The results show important differences in the
Phylogeny of the Australian Camphorosmeae (Chenopodiaceae) and the Taxonomic Significance of the Fruiting Perianth
Phylogenetic hypotheses inferred from molecular data do not support the current taxonomy of Camphorosmeae in Australia, and Neobassia, Threlkeldia, Osteocarpum, and Enchylaena should be subsumed into the species‐rich genera Sclerolaena and Maireana.
Molecular phylogenetic data and seed coat anatomy resolve the generic position of some critical Chenopodioideae (Chenopodiaceae – Amaranthaceae) with reduced perianth segments
The phylogenetic results, as well as presence of the stalactites in the outer cell walls of the testa and lack of the rosulate leaves, confirm the distinctive nature of Monolepisspathulata from all Blitum and, therefore, the recent combination Blitumaspathulatum cannot be accepted.


Phylogenetic analysis of tribe Salsoleae (Chenopodiaceae) based on ribosomal ITS sequences: implications for the evolution of photosynthesis types.
Reconstructed phylogeny of representative species of tribe Salsoleae of subfamily Salsoloideae of angiosperm family Chenopodiaceae indicates separate NAD-ME and NADP-ME lineages and suggests two reversions to C(3) photosynthesis.
Relationships in the Caryophyllales as suggested by phylogenetic analyses of partial chloroplast DNA ORF2280 homolog sequences.
Phylogenetic relationships within the angiosperm order Caryophyllales were investigated by comparative sequencing of two portions of the highly conserved inverted repeat coinciding with the region occupied by ORF2280 in Nicotiana, the largest gene in the plastid genomes of most land plants.
Phylogeny of the Caryophyllales - gene sequence data
The Phytolaccaceae are not monophyletic, and the Caryophyllaceae and Mollugo are the only taxa examined that do not produce betalains but they are neither closely allied nor basal to other elements of the order.
Floral morphology and taxonomic relations among the genera of Amaranthaceae in the New World and the Hawaiian Islands
It is suggested that the type of staminal tubes found in Pseudogomphrena and Froelichia can be derived from that in Alternanthera and froelichiella by reduction of filament length and a fusion of pseudostaminodia with the filaments.
An integrated molecular and morphological study of the subfamily Suaedoideae Ulbr. (Chenopodiaceae)
The molecular results confirm that C4 photosynthesis has evolved independently four times in the subfamily Suaedoideae, and a reassessment of morphological and anatomical characters on the background of the molecular trees resulted in the recognition of pistil morphology and leaf type as key characters.
Molecular phylogenetics of Caryophyllales based on nuclear 18S rDNA and plastid rbcL, atpB, and matK DNA sequences.
Two additional lineages are potentially appropriate to be elevated to the family level in the future: the genera Lophiocarpus and Corbichonia form a well-supported clade on the basis of molecular and chemical evidence, and Limeum appears to be separated from other Molluginaceae based on both molecular and ultrastructural data.
Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences
A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms.
Photosynthetic pathways inChenopodiaceae from Africa, Asia and Europe with their ecological, phytogeographical and taxonomical importance
Close taxonomic relationships between photosynthetic pathways and infrageneric classification in genera with both types of C3 and C4, like Atriplex andSuaeda are found.
A molecular phylogeny of the grass subfamily Panicoideae (Poaceae) shows multiple origins of C4 photosynthesis.
Based on this sample of species, it is inferred that C(4) photosynthesis has evolved independently several times, although a single origin with multiple reversals and several reacquisitions is only slightly less parsimonious.
A phylogenetic analysis of Zygophyllaceae R.Br. based on morphological, anatomical and rbcL DNA sequence data
A combined analysis of molecular and non-molecular data was conducted, and recognition of Peganaceae and Nitrariaceae is recommended, as is a recircumscription of Zygophyllaceae s.s. to comprise five subfamilies.
