“…The current results are in agreement to (De Leonardis, De Santis, Ferrauto, & Fichera, 2009) who determined similar wall ornamentation. In our current results A. burtii have regulate type of ornamentation which in consistent with the previous findings of Baser, Sagıroglu, Dogan, and Duman (2021) on other members of family Apiaceae. Similarly, B. falcatum subsp.…”

The present study was performed to provide a detailed explanation of leaf epidermal anatomy and pollen micromorphological features of selected species of family Apiaceae from Chitral, eastern Hindu Kush region as the basis of forthcoming studies.In the present article pollen morphology of eight species and foliar epidermal of seven species of family Apiaceae have been examined through microscopic techniques. In results two types of pollen prolate (five species) and perprolate (three species) with three colpi have been recorded. The exine ornamentation was found to be regulate, striate, and cerebroid. Largest pollen was found in Heracleum leucocarpum with the polar diameter of 43.25 μm and equatorial diameter of 21.6 μm. Smallest pollen was observed in Elaeosticta chitralica with the polar diameter of 18.4 μm. The P/E ratio varied from 1.59 to 2.16. Regarding to foliar epidermal anatomy, three types of epidermal cells including rectangular, irregular, and polygonal with variation in anticlinal wall pattern were determined. In the selected species three kinds of stomata comprising anisocytic, anomocytic, and paracytic type were reported in the current research. The size of epidermal cells ranged from 106 Â 42.50 μm in Bupleurum falcatum subsp. cernuum and 77.25 Â 26.35 μm in Prangos pabularia in adaxial surface. Largest stomatal complex was found in Prangos pabularia both in adaxial 33.55 Â 20.05 μm and abaxial 50.25 Â 39.40 μm. All the observed quantitative and qualitative features of the species were proved to be useful in the delimitation of species at generic and species level.

“…In this study, the pollen morphology of 17 taxa (18 accessions) of the family Apiaceae (13 Daucus and 4 non-Daucus taxa) was determined, of which 13 taxa (11 Daucus and 2 non-Daucus) were examined for the first time. In all taxa, tricolporate and prolate-perprolate-shaped pollen were observed, which is a common feature of the pollen grains of Apiaceae [48][49][50][51][52].…”

“…We also compared the data included in PalDat for species of different genera belonging to the family Apiaceae that were also analyzed by SEM (50 species representing 31 genera) and verified that the pollen grains of most of these species are rugulate and perforate (or only rugulate/ perforate), suggesting strong homogeneity for this trait in Apiaceae. Nonetheless, outside PalDat, some other types of exine ornamentation in Apiaceae have also been reported in the literature, e.g., cerebroid, pertectate, and verrucate [50][51][52]55].…”

Combining genome size and pollen morphology data to study species relationships in the genus Daucus (Apiaceae)

Background The genus Daucus (Apiaceae) comprises about 40 wild species and the cultivated carrot, a crop of great economic and nutritional importance. The rich genetic diversity of wild Daucus species makes them a valuable gene pool for carrot improvement breeding programs. Therefore, it is essential to have good knowledge of the genome structure and relationships among wild Daucus species. To broaden such knowledge, in this research, the nuclear DNA content for 14 Daucus accessions and four closely related species was estimated by flow cytometry and their pollen morphology was analyzed by light and scanning electron microscopy (SEM). Results The flow cytometric analysis showed a 3.2-fold variation in the mean 2C values among Daucus taxa, ranging from 0.999 (D. carota subsp. sativus) to 3.228 pg (D. littoralis). Among the outgroup species, the mean 2C values were 1.775–2.882 pg. The pollen grains of Daucus were tricolporate, mainly prolate or perprolate (rarely) in shape, and mainly medium or small (rarely) in size (21.19–40.38 µm), whereas the outgroup species had tricolporate, perprolate-shaped, and medium-sized (26.01–49.86 µm) pollen grains. In the studied taxa, SEM analysis revealed that exine ornamentation was striate, rugulate, perforate, or the ornamentation pattern was mixed. At the time of shedding, all pollen grains were three-celled, as evidenced by DAPI staining. We also found high positive correlations between the length of the polar axis (P) and the length of the equatorial diameter (E) of pollen grains, as well as between P and P/E. However, when comparing cytogenetic information with palynological data, no significant correlations were observed. Conclusions This study complements the information on the nuclear DNA content in Daucus and provides comprehensive knowledge of the pollen morphology of its taxa. These findings may be important in elucidating the taxonomic relationships among Daucus species and can help in the correct identification of gene bank accessions. In a broader view, they could also be meaningful for the interpretation of evolutionary trends in the genus.

“…Although Apiaceae is known as a stenopalynous family, recent studies have shown that pollen traits (i.e. shape, aperture and ornamentation) could differ among species (Baldemir et al 2018, Baczyński et al 2021, Başer et al 2021). We thus decided to use light and scanning electron microscopy to conduct a comparative examination of the pollen grains of C. bulbosum , C. karsianum and C. posofianum .…”

The aim of the present study was to analyse the support for reducing Chaerophyllum karsianum and C. posofianum, both local endemic to northeast Anatolia, to synonyms of C. bulbosum. Chaerophyllum karsianum is closely related to C. bulbosum but may be distinguished from it by its pink petals, ciliate bracteoles, entire leaf segments and 12-16 rays. Chaerophyllum posofianum is also closely related to C. bulbosum but differs from it by its entire leaf segments, ciliate bracteoles and purple anthers. However, our field observations and examination of herbarium specimens showed that all these diagnostic morphological characters overlap. The flower color of C. bulbosum ranges from white to purple within populations or even individuals, and the bracteole margin ranges from entire to ciliate. We also investigated and compared the anatomical and micromorphological characteristics of fruits of C. bulbosum, C. karsianum and C. posofianum, but found no diagnostic differences. Furthermore, nucleotide sequence data generated for the present study showed that the internal transcribed spacer sequences of C. karsianum and C. posofianum were identical to those of C. bulbosum. Our results thus strongly support that C. bulbosum, C. karsianum and C. posofianum are conspecific.
