  author={Reinhard M. Fritsch and Frank R. Blattner and Maia Gurushidze},
Allium subgenus Melanocrommyum from Eurasia is taxonomically complicated with different and contradictory taxonomic treatments proposed in the past. A comprehensive study, covering nearly all existing taxonomic groups and their entire geographic distribution, by sequencing the nuclear rDNA internal transcribed spacer region (ITS) confirmed the monophyly of the subgenus, while most traditionally used sections were either para- or polyphyletic. Addition of ten more species and 150 new accessions… Expand
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. Expand
Phylogeny of Allium L. subgenus Anguinum (G. Don. ex W.D.J. Koch) N. Friesen (Amaryllidaceae).
The disjunct distribution of the subgenus Anguinum of the genus Allium makes it a good candidate to test models of Northern hemisphere biogeography, and phylogenetic analysis with the nuclear marker ITS and three different chloroplast markers suggests that the species is of hybridogenous origin.

Interspecific Relationships in Allium Subgenus Melanocrommyum Sections Acanthoprason and Asteroprason (Amaryllidaceae) Revealed Using ISSR Markers
The results showed that ISSR analysis is suitable to detect the relationship of closely related species, and the groups constructed represent alternative proposals to define taxonomic groups. Expand
Allium cyrilli complex (sect. Melanocrommyum) in Turkey
The results of this study show that A. atropurpureum and A. decipiens do not occur in Turkey and Allium cyrilli is represented by 3 subspecies of which 2 are new for science. Expand
Phylogenetic reappraisal of Allium subgenus Cyathophora (Amaryllidaceae) and related taxa, with a proposal of two new sections
The phylogeny of subgenus Cyathophora and representatives of its closely related taxa within Allium were reconstructed based on nrDNA ITS and two plastid fragments, and the phylogenetic relationships among them recovered were consistent with previous findings. Expand
Notes on Allium section Rhizirideum (Amaryllidaceae) in South Korea and northeastern China: with a new species from Ulleungdo Island
Allium dumebuchum from Ulleungdo Island, South Korea, is described as a new species, most similar to A. senescens due to its habits, but is clearly distinguished particularly by its rhomboid scapes in cross-secion, light purple perianth color, entire and narrowly triangular inner filaments, and flowering season from late September. Expand
Two new species of Allium L. sect. Allium (Amaryllidaceae) from Turkey
The seeds are ovate to elliptic and irregularly more or less shrivelled in shape among the investigated taxa, and the largest LA/SA ratio is observed in Allium aybukeae and A. bilgilii. Expand
Karyological studies of Iranian Allium L. (Amaryllidaceae) species with focus on sect. Acanthoprason. 1. Mitotic chromosomes
The karyotypes showed low variation in inter- and intrachromosomal asymmetry especially inside of the taxonomic groups, though satellited chromosomes were good markers for subgenera and even specific for two studied sections of subg. Expand
Bulb tunic anatomy and its taxonomic implication in Allium L. (Amaryllidaceae: Allioideae)
The results indicated the following characters to be most informative at sectional and subgeneric levels: features of calcium oxalate crystals and subepidermal cell layer of the outermost bulb tunic, type of tracheids, and bulbils presence. Expand
Tracking the evolutionary history of the Allium ampeloprasum L. complex (section Allium) provides evidence of the contribution of North African diploids to the formation of allopolyploid horticultural groups
Novel and robust evidence is provided demonstrating that the North African diploid A. ampeloprasum and A. baeticum Algerian tetraploids emerge as an important reservoir of new wild genetic resources of great interest for tracing the origin of crop domestication and for breeding programs of cultivated varieties.
