“…Exine ornamentation (macroreticulate, scabrate, irregular-rugulate, reticulate) and sulcus membrane ornamentation (macrogranulate and plicate-granulate) were varied in the monosulcate pollens of Fritillaria (Kosenko 1999). This variation accepted by later and present studies (Tekşen et al 2010; Hosseini 2018; Samaropoulou et al 2022). The pollen grains of Fritillaria were examined by Tekşen et al (2010) and six types of exine ornamentation had determined (reticulate, reticulate-perforate, suprareticulate, rugulate-reticulate, psilate-perforate, and perforate).…”

“…In contrast, Hu et al (2021) reported only reticulate exine surface ornamentation in the studied members of this genus. In our research, the exine ornamentation in two regions of pollen and sulcus membrane ornamentation were varied and accepted the variation of these qualitative characters in the previous palynological studies (Kosenko 1999; Tekşen et al 2010; Hosseini 2018; Samaropoulou et al 2022). It seems that reticulation and regulation had a major role in exine ornamentation of the equatorial surface and sulcus margin region of most of the taxa of genus Fritillaria based on this research and previous studies (Kosenko 1999; Tekşen et al 2010; Hu et al 2021; Samaropoulou et al 2022).…”

Moreover, five types of sulcus membrane and sulcus apex ornamentation were distinguished (Tekşen et al 2010). Hosseini (2018) determined three main pollen types based on exine ornamentation (reticulate, reticulate-perforate, and suprareticulate) and two sulcus membrane ornamentation (psilate and verrucate).…”

“…Different palynological research provided taxonomical evidence among the taxa of the tribe Lilieae (Kosenko 1999; Ozler and Pehlivan 2007; Tekşen et al 2010; Güven et al 2014; Hosseini 2018; Hu et al 2021; Samaropoulou et al 2022). In this research, we examined combined pollen micromorphological characters and ultrastructure data to complement previous palynological research and were clearer than the taxonomical relationships with palynological data.…”

Pollen micromorphology and ultrastructure of fifteen species from the genera Cardiocrinum, Fritillaria, Lilium, and Notholirion were examined by Light Microscopy (LM), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). Our results showed that all quantitative characters of pollen micromorphology (LM and SEM observation) varied in the studied taxa. Pollen grains in all studied species were oblate except Notholirion bulbuliferum with oblate-spheroidal. The studied species of Fritillaria had medium pollen type and the rest showed large. Although, two major exine ornamentation in central region of equatorial surface and sulcus margin region were seen such as reticulate (taxa of Cardiocrinum) and reticulum-cristatum (taxa of genera of Lilium, and Notholirion). These characters were varied in taxa of Fritillaria in both regions (foveolate-rugulate, reticulate and foveolate). Also, there were three sulcus membrane ornamentation including striate-tuberculate (Fritillaria gibbosa), tuberculate (Lilium lophophorum and with the rest studied taxa of Fritillaria), and macrotuberculate (the genera Cardiocrinum, Lilium, and Notholirion). Moreover, three kinds of lumina types and two kinds of muri types were detected among these taxa. The qualitative and quantitative characters of the pollen wall were varied such as kind of endexine situation, number of intine layers in the sulcus membrane region, and thickness of elements from the pollen wall. Dendrogram of all qualitative and quantitative palynological characters constructed two pollen groups, five pollen types, and four pollen subtypes. The palynological dendrogram verified that Nomocharis is part of genus Lilium. Palynological types supported the heterogeneous phylogenetic situation of Cardiocrinum. Palynological subtypes were partly valuable in delimitation of sectional levels of the genus Lilium.

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.

BACKGROUNDThe wild variety Fritillaria taipaiensis E. B (EB) is known for its superior therapeutic effects, but its limited production cannot meet the demands. As a result, the cultivated variety F. taipaiensis P. Y. Li (PY) has been widely grown. In this study, we conducted a comprehensive analysis comparing EB and PY in terms of external features, Sipeimine content, metabolome, and chloroplast genome to differentiate these two varieties.RESULTSOur research revealed that the petals and pods of EB are green, while those of PY have purple markings. The bulbs of EB contain significantly higher levels of Sipeimine compared to PY. Metabolomic analysis identified 56 differentially expressed metabolites (DMs), with 23 upregulated and 33 downregulated in EB bulbs. Particularly, 3‐Hydroxycinnamic acid and Secoxyloganin may serve as distinctive differential metabolites. These DMs were associated with 17 KEGG pathways, including Pyrimidine metabolism, Alanine, Aspartate and Glutamate, and Galactose metabolism. Differences in the length of the chloroplast genome were primarily observed in the LSC region, with the largest variation in the trnH‐GUC~psbA region. The placement of the trnH gene and the rps gene in proximity to the LSC/IRb boundary differs between EB and PY.CONCLUSIONThe results of this study provide valuable insights for the introduction and comprehensive development of wild F. taipaiensis from a scientific perspective.This article is protected by copyright.
