Phylogeny and new intrageneric classification of Allium (Alliaceae) based on nuclear ribosomal DNA its sequences
The internal transcribed spacer region 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 to form a new classification of genus Allium consisting of 15 monophyletic subgenera.

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. Expand
Evolution of genome size inAllium (Alliaceae)
The 4C DNA amounts of 86 species from Allium subgg.Allium, Rhizirideum, Bromatorrhiza, Melanocrommyum, Caloscordum andAmerallium show a 8.35-fold difference, which shows that a significant loss and/or gain of DNA has occurred during evolution. Expand
New classification of Allium L. subg. Melanocrommyum (Webb & Berthel.) Rouy (Alliaceae) based on molecular and morphological characters.
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.

Taxonomic Importance of Seed Morphology in Allium (Amaryllidaceae)
Seed coat patterns appear to mark different evolutionary levels inside of many taxonomic groups and variation of the testa characters is sufficient to distinguish taxa at sectional level, however, seed coat patterns do not directly indicate basal or advance evolutionary levels. Expand
Phylogenetic analysis of Allium subg. Melanocrommyum infers cryptic species and demands a new sectional classification.
One of the rare cases in plants where morphologically indistinguishable diploid species occurring in mixed populations are non-sister cryptic species is reported, and fingerprint markers show that genome-wide differences between both lineages exist. Expand
Hybrid origin of some ornamentals of Allium subgenus Melanocrommyum verified with GISH and RAPD
Abstract Random amplified polymorphic DNA (RAPD) and genomic in situ hybridization (GISH) methods have been used to verify the hybridogenic origin and to identify the parental species of someExpand
Occurrence and taxonomic significance of cysteine sulphoxides in the genus Allium L. (Alliaceae).
In the genus Allium, methiin-dominated species (rarely used by man) were common, but the occurrence of the other cysteine sulphoxides was variable and was largely correlated with use as spices or vegetables. Expand
Seed characters and testa sculptures of some Iranian Allium L. species (Alliaceae)
The seed coat pattern of most species corresponded well to earlier reports of the same or closely related species, or was at least already reported for not related Allium species. Expand
