    Karyological studies on Oxytropis (Fabaceae) from Turkey
    (UNIV FLORENCE BOTANY INST, 2015) Martin, Esra; Erkul, Seher Karaman; Aytaç, Zeki
    The karyological analyses of 11 species, one taxon of which is endemic of Oxytropis (Fabaceae), distributed in Turkey were examined in this study. Among these taxa, the chromosome numbers were as follows: 2n = 16 in Oxytropis kotschyana, O. pallasii, O. pilosa, O. savellanica, O. persica, O. albana, O. argyroleuca, O. aucheri, O. karjaginii, O. lupinoides; and 2n = 96 in O. lazica. The karyotype analysis of taxa belonging to the genus Oxytropis was performed using Image Analysis System (Bs200Pro).

    Karyotype analyses of 25 Turkish taxa of astragalus from the sections Macrophyllium, Hymenostegis, Hymenocoleus, and Anthylloidei (Fabaceae)
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2019) Martin, Esra; İçyer Doğan, Gizem; Karaman Erkul, Seher; Eroğlu, Haul Erhan
    The karyotype analyses and chromosomal data of 25 taxa belonging to the sections Macrophyllium, Hymenostegis, Hymenocoleus, and Anthylloidei of the genus Astragalus naturally distributed in Turkey are described. The cytogenetic data obtained were evaluated systematically. The following somatic chromosome numbers were found: 2n = 16 for A. oleaefolius, A. dipodurus, A. cephalotes, and A. yukselii; 2n = 32 for A. longifolius; and 2n = 48 for A. isauricus in the sect. Macrophyllium; 2n = 16 for A. zohrabi, A. sosnowskyi, A. velenovskyi, A. trifoliastrum, and A. uraniolimneus; 2n = 18 for A. hymenocystis; 2n= 48 for A. lagopoides, A. gueruenensis, and A. ciloensis; and 2n = 64 for A. hirticalyx in the sect. Hymenostegis; 2n = 48 for A. vaginans in the sect. Hymenocoleus; and 2n= 16 for A. szowitsii, A. ermineus, A. zederbaueri, A. anthylloides, A. halicacabus, A. chardinii, and A. wagneri; and 2n = 48 for A. surugensis in the sect. Anthylloidei. In all taxa, the karyotype results were obtained for the first time. A. szowitsii is the most symmetrical karyotype in both index values. While A. zohrabi is the most asymmetrical karyotype in intrachromosomal asymmetry, A. wagneri is the most asymmetrical karyotype in interchromosomal asymmetry.
