  author={Nikolai Friesen and Reinhard M. Fritsch and Frank R. Blattner},
The internal transcribed spacer region (ITS) of nuclear ribosomal DNA was sequenced from 195 representative species of Allium, two species of Nothoscordum, and one species each of Ipheion, Dichelostemma, and Tulbaghia. Within the Allium species the lengths of the ITS regions were in a range from 612 to 661 base pairs and pairwise genetic distances reached up to 46%. The ITS data supported the inclusion of Nectaroscordum, Caloscordum, and Milula into Allium. Subgenera Rhizirideum and Allium, as…

Taxonomy and phylogenetics of Allium section Decipientia (Amaryllidaceae): morphological characters do not reflect the evolutionary history revealed by molecular markers
A molecular phylogenetic tree based on predominantly non-coding sequences from nuclear ribosomal RNA and four plastid regions is constructed and does not reveal a clear relationship between these three monophyletic groups.
Phylogenetic relationships of Iranian Allium sect. Allium (Amaryllidaceae, Allioideae) as inferred from nrDNA ITS, cpDNA rps16 and trn L–F sequences
The hypothesis of a possible hybrid origin of A. ampeloprasum is supported based on selected samples of this species and its putative relatives in A. Allium from Iran, which formed a clade in the plastid tree, but was resolved as paraphyletic in the nrITS tree, probably due to presence of multiple non‐concerted copies of nr ITS.
Phylogeny and biogeography of Allium (Amaryllidaceae: Allieae) based on nuclear ribosomal internal transcribed spacer and chloroplast rps16 sequences, focusing on the inclusion of species endemic to China.
Phylogenetic analyses indicate that Allium is monophyletic and consists of three major clades, but that some subgenera are not, and molecular data suggest that its evolution proceeded along three separate evolutionary lines.
Identification of hypervariable chloroplast intergenic sequences in onion (Allium cepa L.) and their use in analysing the origins of male-sterile onion cytotypes
Phylogenetic analysis revealed that A. vavilovii and A. dictyoprasum were close relatives of the normal and cytoplasmic male sterile (CMS)-T cytotypes of onion, and that the sequences of thenormal and CMS-T cytotype were identical, supporting the recent autoplasmic origin of CMS- T male-sterility from the normal cytotype.
Phylogeny of Allium L. subgenus Anguinum (G. Don. ex W.D.J. Koch) N. Friesen (Amaryllidaceae).
Phylogenetic relationships of wild and cultivated species of Allium section Cepa inferred by nuclear rDNA ITS sequence analysis
It is argued that a subdivision of section CepA in subsections Cepa and Phyllodolon, although possible from data, as well as the formal description of alliances do not seem reasonable in a small group of species.
Phylogenetic relationships of ornamental species in Allium L. subg. Melanocrommyum (Webb et Berthel.) Rouy (Alliaceae)
About 30 ornamental Allium species are affiliated to nine sections of subg. Melanocrommyum. Recent molecular investigations (sequences of the Internal Transcribed Spacer of nuclear DNA and the
Molecular phylogeny of Galanthus (Amaryllidaceae) of Anatolia inferred from multiple nuclear and chloroplast DNA regions
The data confirm the identity of Galanthus koenenianus as a new taxon, well separated from G. alpinus; both are clustered within subseries Viridifolii, rather than within sub series Glaucaefolii in contrast to previous suggestions, but in accordance with their geographical occurrence.


Phylogeny of Allium L. subg. Melanocrommyum (Webb et Berth.) Rouy based on DNA sequence analysis of the internal transcribed spacer region of nrDNA
Sequence analysis of the ITS region of nuclear ribosomal DNA from subgeneric representatives of Allium L. cernuum produced phylogenetic trees which concurred with previous conclusions based on classical taxonomy, but the phylogenetic positions of Allio protensum and Allium macleanii did not correspond to their morphological similarity with Allium schubertii and Allio giganteum, respectively.
Criteria for sampling in Allium (Alliaceae) based on chloroplast DNA PCR-RFLPs
Variation of approximately 20 kb of non-coding regions of the chloroplast genome of 29 species of Allium and 7 species of related genera have been cladistically analyzed and indicate that recognition of the monotypic Nectaroscordum siculuim renders Allium paraphyletic.
Molecular and morphological evidence for an origin of the aberrant genus Milula within himalayan species of Allium (Alliacae).
To maintain Allium as monophyletic, Milula has been included as A. spicatum in Allium subgenus Rhizirideum, and Anatomical investigations of leaf characters support a close relationship of Milula with A. cyathophorum.
Use of chloroplast DNA polymorphisms for the phylogenetic study of the subgenera Amerallium and Bromatorrhiza (genus Allium)
These E Himalayan–SW Chinese plants take an intermediate position between the two large x = 7 and x = 8 subgroups of Allium, suggesting a key role for them as a basic group in the diversification process of the genus.
A Molecular Phylogeny of the Grass Family (Poaceae) Based on the Sequences of Nuclear Ribosomal DNA (ITS)
The ITS phylogeny of the grass family, and evidence from the chloroplast genome, cytogenetics, fossil records, biogeography, and plate tectonic theory, suggest that the origin of the Grasses is probably ‘out of South America’.
RAPDs and noncoding chloroplast DNA reveal a single origin of the cultivated Allium fistulosum from A. altaicum (Alliaceae).
The origin of the crop species Allium fistulosum (bunching onion) and its relation to its wild relative A. altaicum were surveyed with a restriction fragment length polymorphism (RFLP) analysis and with a random amplified polymorhic DNA (RAPD) analysis of nuclear DNA.
Biodiversity assessment based on cpDNA and crossability analysis in selected species of Allium subgenus Rhizirideum
The hypothesis that a shorter distance between two species in a cpDNA tree compared to their distance in a nDNA tree will indicate interfertility at a certain level, is neither confirmed nor rejected by the currently available results.
Use of chloroplast DNA polymorphisms for the phylogenetic study of Allium subgenus Amerallium and subgenus Bromatorrhiza (Alliaceae) II
The parsimony analysis confirms strongly the subdivision of the genus Allium in two main groups with different basic chromosome numbers, which had been earlier proposed on the basis of morphological, karyological, anatomical and other molecular markers.
Phylogeny of Allium L. subgenus Rhizirideum (G. Don ex Koch) Wendelbo according to dot blot hybridization with randomly amplified DNA probes
Among 341 randomly amplified DNA sequences generated from 11 Allium species, 55 were purified by gel excision and subsequent reamplification by PCR and generated a phyllogram which basically conformed to the classification system proposed by the Gatersleben (Germany) group.
