“…Worldwide, more than 460 taxa of Allium have been investigated for their seed macro- and micro-morphological characteristics [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ]. The highest number of species have been studied from Turkey, China (Xinjiang), and Iran with 62, 38 and 23 species, respectively [ 28 , 31 , 32 ].…”

“…This subgenus consists of 140 species and it is the second largest subgenus of the second evolutionary line in genus Allium [ 7 , 23 ]. Seed testa structure of 120 taxa has been studied in this subgenus [ 16 , 17 , 18 , 19 , 20 , 23 , 24 , 28 , 31 , 33 , 45 , 46 , 48 ]. The subg.…”

“…In addition, Veiskarami et al [ 32 ] investigated seed size and shape as well as micro-morphology of 23 species belonging to two subgenera and six sections in Iran. Currently, several new taxa have been recognized in this genus based on their morphology including seed macro- and micro-morphological characteristics and phylogenetic studies [ 29 , 33 ]. Some other characteristics that provide important taxonomic information in Allium for infrageneric groups are anatomy of bulb tunic, scape, and pollen morphology [ 29 , 34 , 35 , 36 ].…”

We studied seed macro- and micro-morphological characteristics of 48 Allium species (51 accessions) belonging to 24 sections and 7 subgenera. Our taxonomic sampling focused on the central Asian regions of Uzbekistan, Kyrgyzstan, and Mongolia. The seed length ranged between 1.74 ± 0.16–4.47 ± 0.43 mm and width ranged between 1.06 ± 0.08–3.44 ± 0.23 mm, showing various shapes. The irregular and elongated polygonal testa cells occurred in all investigated species. Seed testa sculptures showed high variation in their anticlinal walls associated with different shapes: straight to with U-, S- or Omega-type undulations among the species. The moderately flat to convex periclinal walls with various sized verrucae or granules were found in all investigated taxa. Based on our research, we conclude that seed characteristics such as size, shape, and the seed testa features show their significant variability, revealing key characteristics to support taxonomic relationships and major clades recovered in the molecular phylogeny of the genus Allium. Especially, the anticlinal wall characteristics were highly variable and decisive at the both section and species levels. In addition, widely varied shapes and sizes of the seeds were remarkably effective to distinguish Allium species.

“…Macro‐ and micro‐morphological and anatomical characters have proven to be useful for delineation of taxa (Namin et al , Choi et al , Bécquer et al , Lin and Tan ), and in Allium seed testa micromorphological characters are necessary and important in descriptions of new taxa (Deniz et al ). We conclude that stable and distinct seed micromorphological characters can be used to identify species and that they reflect taxonomic relationships and evolutionary levels.…”

Micromorphological characteristics of the seed testa of 38 species belonging to 19 sections and seven subgenera of Allium from central Asia have been evaluated with a scanning electron microscope (SEM). Several taxonomically significant characters were found. The results showed that the epidermis consists of polygonal cells with different dimensions, that the cellular arrangement is tight or loose with or without reticulate tissue, and that the arrangement of cells is regular or irregular. The main variation was found in the anticlinal walls, of which the outline could be straight, straight to arched, arched or undulating like an S or U. Convex and (or) concave verrucate periclinal walls occurred in all species investigated. Based on the characteristics of the anticlinal and periclinal walls of the 38 species, six groups of Allium were distinguished, and a dichotomous key for them is presented. The cellular arrangement and periclinal and anticlinal wall traits of the 38 species of Allium were found stable and distinct within a species, but showed great differences among species. We conclude that seed epidermal characteristics provide useful and important information for distinguishing species of Allium, and thus they have taxonomic significance.

The genus Allium is one of the largest monocotyledonous genera, containing over 850 species, and most of these species are found in temperate climates of the Northern Hemisphere. Furthermore, as a large number of new Allium species continue to be identified, phylogenetic classification based on morphological characteristics and a few genetic markers will gradually exhibit extremely low discriminatory power. In this study, we present the use of complete chloroplast genome sequences in genome-scale phylogenetic studies of Allium . We sequenced and assembled four Allium chloroplast genomes and retrieved five published chloroplast genomes from GenBank. All nine chloroplast genomes were used for genomic comparison and phylogenetic inference. The chloroplast genomes, ranging from 152,387 bp to 154,482 bp in length, exhibited conservation of genomic structure, and gene organization and order. Subsequently, we observed the expansion of IRs from the basal monocot Acorus americanus to Allium , identified 814 simple sequence repeats, 131 tandem repeats, 154 dispersed repeats and 109 palindromic repeats, and found six highly variable regions. The phylogenetic relationships of the Allium species inferred from the chloroplast genomes obtained high support, indicating that chloroplast genome data will be useful for further resolution of the phylogeny of the genus Allium .
