Caryological study on four Hesperis L. (Cruciferae) taxa from the Diaplictos (Dvorak) Dvorak section in Turkey
(WILEY-BLACKWELL, 2008) Unal, Fatma; Duran, Ahmet; Martin, Esra
This study examined chromosome numbers and karyotypes of four taxa, Hesperis novakii Dvorak, H. bottae Fourn., H. balansae Fourn. and H. syriaca (DC.) Dvorak, from naturally growing Diaplictos (Dvorak) Dvorak section, which is represented by only these four taxa in Turkey, in the genus Hesperis. H. novakii and H. syriaca have 2n=14 chromosomes, H. bottae and H. balansae have 2n=12 chromosomes in somatic cells. Total chromosome lengths are 5.37 mu m and 2.17 mu m in H. novakii, 5.38 mu m and 2.70 mu m in H. bottae, 9.59 mu m and 4.28 mu m in H. balansae, 4.88 mu m and 2.32 mu m in H. syriaca (no. 4969), 7.89 mu m and 3.44 mu m in H. syriaca (no. 4971). The karyotypes are as follows: H. novakii consists of 3m+1sm+1st+2T, H. bottae consists of 4m+2st, H. balansae consists of 4m+2sm, H. syriaca (no. 4969) consists of 3m+1sm+1st+2T and H. syriaca (no. 4971) consists of 3m+1sm+1st+2T chromosome pairs. Results were discussed from a cytological and taxonomical point of view.
Chromosome numbers of species of the genus Jurinea Cass. (Asteraceae) in Turkey
(UNIV FLORENCE BOTANY INST, 2009) Bekir, Dogan; Duran, Ahmet; Martin, Esra; Hakki, Erdogan Esref
Chromosome numbers of 13 Jurinea species, collected from different localities in Turkey, were determined for the first time. All the Jurinea species investigated were diploid with chromosome numbers counted as 2n = 34. The basic chromosome number of the genus was x = 17. In this study, polyploidy was determined in nine taxa of Jurinea. Polyploid cells were 2n = 4x = 68 and they were tetraploid. The mitotic metaphase plates were given all the taxa of Jurinea. The research has made contribution to the cytotaxonomic revision of the genus Jurinea in Turkey.
Contribution to the cytotaxonomic knowledge of 10 species of Klasea Cass. (Asteraceae) from Turkey
(UNIV FLORENCE BOTANY INST, 2015) Martin, Esra; Dogan, Bekir; Duran, Ahmet; Coskun, Fatih; Altinordu, Fahim
In the present study, karyotype analyses of 10 taxa belongs to the genus Klasea Cass. (Asteraceae) were conducted. Somatic chromosome numbers are not a distinctive character of classification of Klasea taxa. All of the taxa were counted as 2n = 30 chromosomes, except for Klasea radiata subsp. biebersteiniana (2n = 60). Although all the taxa have a chromosome number of 2n = 30, they could be differentiated by their karyotype formula and quantitative parameters of the karyotype. Karyotype analysis was performed by means of an Image Analysis System and karyotype asymmetry indices were measured. According to these parameters, karyological relationships among studied taxa were inferred.
Cytogenetical Analysis of 12 Taxa of Genista L. (Fabaceae) From Turkey
(2009) Martin, Esra; Dinç, Muhittin; Duran, Ahmet; Doğan, Bekir; Hakkı, Erdoğan E.
In this study, cytogenetical analyses of 12 taxa belonging to the genus Genista L. and grown naturally in Turkey were conducted. These taxa include G. acanthoclada, G. albida, G. anatolica, G. aucheri, G. burdurensis, G. carinalis, G. involucrata, G. januensis subsp. lydia, G. sandrasica, G. sessilifolia, G. tinctoria and G. vuralii. Chromosome numbers of all the taxa, except G. tinctoria, are introduced to the scientific community for the first time. Somatic metaphase chromosomes of the genus were determined as 2n = 18, 36, 46, 48, 52, 72 and 144. Polyploidy was observed in the cells of G. albida (2n = 18, 2n = 4x = 36), G. tinctoria (2n = 36, 48, 2n = 4x = 96), G. januensis subsp. lydia (2n = 46, 2n = 4x = 92), G. burdurensis and G. sessilifolia (2n = 48, 2n = 4x = 96). Somatic chromosomes of the G. sandrasica are very small, thus exact ploidy level of polyploidy was not determined. Karyotype analysis of G. albida and G. involucrata were performed via an Image Analysis System.

Fruit and seed morphology of six species previously placed in Malcolmia (Brassicaceae) in Turkey and their taxonomic value
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2011) Kaya, Ayla; Unal, Murat; Ozgokce, Fevzi; Dogan, Bekir; Martin, Esra
The fruit and seed morphologies of 6 species previously placed in the genus Malcolmia W.T.Aiton were examined with stereomicroscopy and scanning electron microscopy (SEM) in order to determine the significance of fruit and seed features as taxonomic characters. This study presents macro- and micromorphological characters, including fruit and seed shape, size, colour, fruiting pedicel size, fruit hair and density, seed coat pattern, epidermal cell shape, and anticlinal and periclinal cell walls. The results showed that the morphological characteristics of the fruit and seed could be used as criteria to distinguish genera and tribes. The investigated features of specimens indicated that Malcolmia chia (L.) DC. and M.flexuosa (Sikh. & Sm.) Sibth. & Sm. should remain in the genus that belongs to the tribe Anastaticeae. Malcolmia crenulata (DC.) Boiss. and M. exacoides (DC.) Spreng. belong to the genus Zuvanda (Dvorak) Askerova of the tribe Conringieae. Finally, Malcolmia africana (L.) W.T.Aiton and M. intermedia C.A.Mey. belong to the genus Strigosella Boiss. of the tribe Euclidieae. A key is provided for the identification of the investigated species based on fruit and seed characters.
Karyological studies in some Glycyrrhiza (Fabaceae) taxa from Turkey
(TAYLOR & FRANCIS LTD, 2015) Cetina, Ozlem; Duran, Ahmet; Martin, Esra; Kucukoduk, Mustafa
Chromosome number, size and morphology of five taxa of the genus Glycyrrhiza growing naturally in Turkey were investigated. Permanent slides were made by using the standard liquid nitrogen method. Karyotypes were determined using Image Analysis System (Bs200Pro). In addition, the karyotype asymmetry of each taxa was evaluated by different methods: TF%, AsK%, Rec and Syi, A(1), A(2), A, AI and Stebbins classification. Correlations between the karyotype asymmetries of the different taxa were calculated. Two different chromosome numbers were found in the studied taxa; 2n = 16 in Glycyrrhiza echinata, G. glabra, G. flavescens subsp. flavescens, G. flavescens subsp. antalyensis and 2n = 14 in G. asymmetrica. The karyological data were evaluated with the NTYSY software package and used to create a dendrogram. The results were compared with previous cytological data. Photos of the taxa in their natural environment are also presented.

Karyological Studies of Six Endemic Species of Stachys (Lamiaceae) Subsect. Fragiles from Turkey
(UNIV TOKYO CYTOLOGIA, 2016) Martin, Esra; Altınordu, Fahim; Güner, Özal; Akçiçek, Ekrem
Several chromosome numbers are reported for Stachys taxa but little information is available about chromosome morphology. Thus, this study aims to investigate the karyotypes of six endemic Stachys species from Turkey. Two different chromosome numbers are reported as 2n=30 (Stachys chasmosericea and S. pinardii) and 2n=34 (S. euadenia, S. buttleri, S. pseudopinardii and S. longiflora). The chromosome types of the studied taxa are metacentric and submetacentric. Karyological features and asymmetry indices (M-CA, CVCI and CVCL) of the six endemic species are identified for the first time, and karyological relationships are determined. Also we presented published chromosome data of Stachys along with new counts. These data can be used for chromosome number evolution for the genus and helpful for understanding its evolution.
