“…The results obtained in the current research confirm that some palynological characters, such as polar diameter, equatorial diameter, diameter in polar view, exine thickness, intine thickness, pore length, colpus width and spine length, may serve as diagnostic characters for Doronicum taxonomy. These results are consistent with palynological studies on various genera within the family Asteraceae (Zafar et al 2007;Faghir et al 2015;Badry et al 2020;Ali et al 2021).…”

“…Doronicum pollen grains are found to be medium-sized, as are those of Acmella Rich. (Joujeh et al 2019), Centaurea L. (Reshmi and Rajalakshmi 2019), and Carlina L. (Badry et al 2020).…”

“…Since the qualitative character ornamentation and pollen shape are the same in all taxa, these characters were not used in the statistical analysis. Single-linkage HCA was carried out based on the Euclidian distance measure and using the unweighted pair-group method with arithmetic mean (UPGMA) (Sokal 1958; Badry et al 2020). In the HCA analysis, the taxonomic distance of each species from other operational taxonomic units (OTUs) was calculated.…”

The main purpose of this study is the palynological characterization of Doronicum L. taxa that occur naturally in Turkey. In this context, the pollen morphology of 11 species and one subspecies of Doronicum was researched in detail by light microscopy and scanning electron microscopy (SEM). Furthermore, principal component analysis (PCA) and hierarchical cluster analysis (HCA) were carried out to identify closely related species and palynological characters that could potentially be used to distinguish the studied taxa. Pollen grains were found to be isopolar monad and tricolporate. Pollen were prolate-spheroidal in shape, with a circular amb. SEM showed the exine ornamentation was echinate-perforate. Differences in the bases and ends of the spines were observed; therefore, pollen grains were categorized based on spine morphology. Three components of the studied palynological characteristics were determined with PCA. The PCA results explained 78.79% of the variation, and polar diameter, equatorial diameter, diameter in polar view, exine thickness, intine thickness, pore length, colpus width, and spine length were found to be the most valuable palynological characteristics for discrimination of the Doronicum taxa. The HCA dendrogram also revealed three main clusters. This study is helpful for understanding the relationships among the taxa of Doronicum and provides insight for future taxonomic research.

“…To distinguish the studied taxa, 21 characteristics as micro and macromorphology, comprising seven quantitative and fourteen qualitative characters were used. Binary, qualitative and quantitative characters were used based on general coefficient similarity [74–76] . Also, 21 characteristics, comprising 14 chemical contents, 4 anticancer activities and 3 percentage of apoptotic cells were used.…”

Garlic and onions are used as food and for medicinal purposes worldwide. Allium L. species are rich in bioactive organosulphur compounds that exhibit many biological activities like anticancer, antimicrobial, antihypertensive, antidiabetic activities. In this study, macro‐ and micromorphological characteristics of four Allium taxa were examined and the results suggested that A. callimischon subsp. haemostictum was the outgroup to sect. Cupanioscordum. Also, for the genus Allium, which is a taxonomically difficult genus, the hypothesis that chemical content and bioactivity can also be used taxonomically in addition to micro and macromorphological characters has been questioned. The bulb extract was analyzed to determine their volatile compositions and anticancer activities against human breast cancer, human cervical cancer, and rat glioma cells for the first time in the literature. To detect the volatiles, the Head Space‐Solid Phase Micro Extraction method was used followed by Gas Chromatography‐Mass Spectrometry. The main compounds were found as dimethyl disulfide that (36.9 %, 63.8 %, 81.9 %, 12.2 %) and methyl (methylthio)‐methyl disulfide (10.8 %, 6.9 %, 14.9 %, 60.0 %) for A. peroninianum, A. hirtovaginatum and A. callidyction, respectively. Additionally, methyl‐trans‐propenyl disulfide is detected for A. peroniniaum (36 %). As a result, all extracts have shown significant efficacy against MCF‐7 cells depending on applied concentrations. The treatment of MCF‐7 cells for 24 h with 10, 50, 200, or 400 μg/mL ethanolic bulb extract of four Allium species resulted in DNA synthesis inhibition. Survival rates for A. peroninianum was 51.3 %, 49.7 %, 42.2 %, 42.0 %, for A. callimischon subsp. haemostictum 62.5 %, 63.0 %, 23.2 %, 22 %, for A. hirtovaginatum 52.9 %, 42.2 %, 42.4 %, 39.9 %, for A. callidyction 51.8 %, 43.2 %, 39.1 %, 31.3 %, for cisplatin 59.6 %, 59.9 %, 50,9 %, 48.2 %, respectively. Moreover, taxonomic evaluation according to biochemical compounds and bioactivities is almost in agreement with that made according to micro and macromorphological characters.

This electron microscope study investigated the micromorphological characteristics of the leaf epidermis of 5 species (10 populations) of Ribes (Grossulariaceae) in Iran: R. biebersteinii, R. uva‐crispa, R. orientale, R. aureum, and R. khorasanicum. Samples were collected and identified, and the similarities between the species were evaluated using information from micromorphological traits of leaf epidermis and multivariate analysis (cluster analysis and principal component analysis). The traits useful for discriminating the species were presence or absence of hairs and glandular trichomes, presence or absence of granular with verrucae on hair surface, position of hairs on epidermal surface, hair location on the leaf (lamina, leaf margin, midrib), stomata shape, wax distribution on stomata, prominence and shape of anticlinal walls and outer periclinal layer, and epicuticular wax sculpturing. An identification key based on these leaf micromorphological characters is provided for Ribes species in Iran. The multivariate analysis of micromorphological traits was efficient for inter‐ and intra‐specific delimitation. The present findings correspond to a large extent with existing classifications.
