“…There are some previous reports on the pollen morphology of the family Resedaceae, including Mitra and Mitra (1979), Yildirim and Şenol (2014), Çilden et al (2018, 2021) and Çilden and Yildirimli (2020). Punt and Marks (1995) and El Naggar (2002) considered that pollen morphology is of high systematic importance, especially for the study of inter‐ and intrageneric relationships within the family.…”

The pollen morphology of Resedaceae in Iran has been studied using light and scanning electron microscopy and described in detail for the first time. Although most of the species had prolate or perprolate pollen grains, variation was observed in other diagnostic pollen characters. Based on exine ornamentation, the pollen grains could be divided into six main types: reticulate, macroreticulate, microreticulate, reticulatestriate, rugulate and perforate, and eight subtypes. In addition, the studied species varied in pollen size, shape in equatorial and polar views, aperture features and ornamentation, representing Resedaceae as a eurypalynous family. The largest pollen grains belonged to Reseda lutea L., while R. aucheri subsp. rotundifolia (Kotschy ex Müll. Arg.) Rech.f. had the smallest ones. Furthermore, species of Ochradenus, Oligomeris and Reseda showed diagnostic palynological characteristics that may provide a better understanding of the taxonomy of Resedaceae. A dichotomous key based on pollen morphology to the 27 Resedaceae taxa native to Iran are also presented.

“…Genus Reseda contains approximately 65 species throughout the world, mostly restricted to the Mediterranean basin. Several of its species flourish on soils under arid environments, while others are ruderal weeds and only a few are available in high mountains [ 19 ]. Pharmacological studies of various Reseda species showed antimicrobial [ 20 ], anti-inflammatory [ 21 ], and antioxidant [ 22 ] activities.…”

Genome size is one of the fundamental cytogenetic features of a species, which is critical for the design and initiation of any genome sequencing projects and can provide essential insights in studying taxonomy, cytogenetics, phylogenesis, and evolutionary studies. However, this key cytogenetic information is almost lacking in the endemic species Reseda pentagyna and the locally rare species Reseda lutea in Saudi Arabia. Therefore, genome size was analyzed by propidium iodide PI flow cytometry and compared to k-mer analysis methods. The standard method for genome size measures (flow cytometry) estimated the genome size of R. lutea and R. pentagyna with nuclei isolation MB01 buffer were found to be 1.91 ± 0.02 and 2.09 ± 0.03 pg/2 °C, respectively, which corresponded approximately to a haploid genome size of 934 and 1.022 Mbp, respectively. For validation, K-mer analysis was performed on both species’ Illumina paired-end sequencing data from both species. Five k-mer analysis approaches were examined for biocomputational estimation of genome size: A general formula and four well-known programs (CovEST, Kmergenie, FindGSE, and GenomeScope). The parameter preferences had a significant impact on GenomeScope and Kmergenie estimates. While the general formula estimations did not differ considerably, with an average genome size of 867.7 and 896. Mbp. The differences across flow cytometry and biocomputational predictions may be due to the high repeat content, particularly long repetitive regions in both genomes, 71% and 57%, which interfered with k-mer analysis. GenomeScope allowed quantification of high heterozygosity levels (1.04 and 1.37%) of R. lutea and R. pentagyna genomes, respectively. Based on our observations, R. lutea may have a tetraploid genome or higher. Our results revealed fundamental cytogenetic information for R. lutea and R. pentagyna, which should be used in future taxonomic studies and whole-genome sequencing.

Seed micromorphology of 18 taxa belonging to the genus Reseda (Resedaceae) in Turkey were investigated with scanning electron microscopy (SEM), in order to understand and check its diagnostic significance at subgeneric and sectional level. Seeds of Reseda species were photographed to evaluate different characteristics including appearance of the seed, testa ornamentation and the existence of carunculoid tissue at hilum regions. In addition, cluster analysis and principal component analysis (PCA) were performed to test whether the micromorphological data of the related taxa is compatible with the current classification of the genus. According to seed micromorphology, Reseda taxa in Turkey are divided into four main groups particularly by testa ornamentation as papillose, rugose, rugulose, and smooth. These results are also in agreement with the sectional classification of the genus in morphological and molecular perspective. The tree topology of Unweighted Pair Group Method with Arithmetic Average based on seed features supported the traditional classification. Principle component analysis revealed testa surface ornamentation as the most distinctive character for species identification. PCA also confirms our cluster grouping of the subgeneric and sectional classification of the taxa in Turkey. An identification key for the genus Reseda in Turkey is provided in the light of current data. The seed data is helpful for the identification of the genus Reseda in Turkey at sectional level. However, for an accurate identification at specific level, seed micromorphology is not sufficient alone and must be evaluated together with all diagnostic morphological features.
