    Fruit and seed macro- and micromorphologies of the genus Matthiola (Brassicaceae) in Turkey and their taxonomic value
    (Tubitak Scientific & Technological Research Council Turkey, 2019) Kaya, Ayla; Unal, Murat; Sefali, Abdurrahman; Martin, Esra
    Macro- and micromorphological features of fruit and seeds belonging to 12 taxa genera of Matthiola W.T. Aiton were studied via stereomicroscope and scanning electron microscope. In macromorphological studies, the following variables were investigated: the shape, size, and color of fruit and seeds; the length of fruiting pedicel; the structure of the median vein; stigma (horns); and trichome properties and density in fruit. In micromorphological studies, the presence or absence of seed wings, seed coat pattern in disc and wing, and epidermal cell shape in disc and wing were determined. According to our findings, all characters of fruit and seeds are extremely variable and can be used as criteria to distinguish species of the genus.

    Karyotype Analyses of the Genus Matthiola (Brassicaceae) in Turkey
    (Univ Tokyo Cytologia, 2016) Martin, Esra; Unal, Murat; Dogan, Bekir; Altinordu, Fahim; Sefali, Abdurrahman; Kaya, Ayla
    In the present paper, karyotype analyses are reported for 12 taxa of Matthiola from Turkey. Matthiola trojana Dirmenci, Satil & Ttimen, M odoratissima (Pall.) R.Br., M anchonifolia Hub.-Mor., M montana Boiss., M fruticulosa (L.) Maire ssp. fruticulosa and M ovatifolia (Boiss.) Boiss. counted 2n=12 chromosomes, and M incana (L.) R.Br., M longipetala (Vent.) DC. ssp. bicornis (Sibth. et Smith) P. W. Ball, M longipetala (Vent.) DC. ssp. longipetala, M longipetala (Vent.) DC. ssp. pumilio (Sibth. & Smith) P. W. Ball, M sinuata (L.) R.Br., and M tricuspidata (L.) R.Br. showed 2n=14 chromosomes. The idiograms and karyomorphometric data obtained by using Image Analysis System (Bs200Pro). The chromosome number of M montana was determined for the first time. Also, karyotype asymmetry index such as M-CA, CVCL and CVCL were measured for the reconstruction of karyological relationships.

    POLLEN MORPHOLOGY OF SIX SPECIES PREVIOUSLY PLACED IN MALCOLMIA (BRASSICACEAE) IN TURKEY
    (Bangladesh Botanical Soc, 2017) Kaya, Ayla; Unal, Murat; Ozgokce, Fevzi; Dogan, Bekir; Martin, Esra
    The genus Malcolmia R. Br. (Brassicaceae) is taxonomically problematic and some of its species have recently been transferred to the genera Strigosella Boiss. and Zuvanda Dvorak. In this study, pollen morphology of some species of Malcolmia, Strigosella and Zuvanda, previously placed in illalcolmia genus, were examined under scanning electron microscope (SEM), in order to determine the significance of pollen features as taxonomic characters. The results reveal rather uniform morphological features, however fine details are characteristic to distinguishing pollen grains in the species of the genus. The pollen grains in three genera are tricolpate and the surface sculpturing type is reticulate. The basic shape of the pollen grains in species studied is euprolate, subprolate-euprolate and euprolate-perprolate. While pollen grains of S. africana is the smallest in all examined species, M. chic is the.biggest. However, three genera can be easily separated by the length of the polar and equatorial axes themselves.

    Study of phylogenetic relationship of Turkish species of Matthiola (Brassicaceae) based on ISSR amplification
    (Tubitak Scientific & Technological Research Council Turkey, 2016) Dogan, Bekir; Celik, Mustafa; Unal, Murat; Sefali, Abdurrahman; Martin, Esra; Kaya, Ayla
    Matthiola W.T. Aiton is a taxonomically complex genus in which there are many problems, mostly with Matthiola longipetala and M. odoratissima. Matthiola species native to Turkey were collected from various locations in Anatolia, and their DNA was isolated. Revision studies performed on the basis of molecular data obtained from studies conducted in recent years have made the phylogenetic relationships and systematic positions of the taxa more apparent and reliable. Consequently, the remaining taxonomic problems among the species have been resolved through the use of DNA-based molecular analysis methods, which, unlike phenotype studies, are not affected by environmental factors. The inter-simple sequence repeat (ISSR) fingerprinting method was used in the study because its properties were considered to be more reliable and consistent than those of the randomly amplified polymorphic DNA method. DNA fragments were amplified through the use of ISSR primers. The phylogenetic relationships among the taxa were represented on a dendrogram constructed through means of NTSYSpc 2.02 software. The infrageneric and intergeneric phylogenetic relationships between Matthiola and other related genera were also characterized. It was determined that the taxa Matthiola odoratissima and M. ovatifolia are separate but closely related. Moreover, it was observed that the Matthiola longipetala complex forms a separate group within the genera. Clearly, the genera Matthiola, Sterigmostemum, Strigosella, Malcolmia, and Chorispora are phylogenetically differentiated on the dendrogram.
