Influence Of Salicylic Acid On Phytochelatin Synthesis In Zea Mays During Cd Stress, Gabriella Szalai, Alexander Krantev, Rusina Yordanova, Losanka Petrova Popova, Tibor Janda
Turkish Journal of Botany
Presoaking maize (Zea mays) seeds in salicylic acid (SA) reduces damage caused by cadmium. In the present work the possible role of phytochelatins (PCs) in SA-mediated protection against Cd toxicity was investigated. Seeds were presoaked in 0.5 mM SA, and seedlings were grown in hydroponic solution containing 0, 0.01, 0.015, or 0.025 mM Cd. Treatment with Cd increased the PC levels in maize roots, but only slight changes were observed in the leaves. Long-term exposure to Cd decreased the phytochelatin synthase (PCS) activity in the roots and led to an increase in PCS and glutathione reductase (GR) activities in maize …

Morphological And Genetic Variation Within And Among Four Quercus Petraea And Q. Robur Natural Populations, Cengi̇z Yücedağ, Oliver Gailing
Turkish Journal of Botany
Numeric-taxonomical and molecular techniques [nuclear simple sequence repeats (nSSRs), expressed sequence tag (EST) SSRs, and chloroplast SSRs] were used to estimate morphological and genetic differentiation within and among 4 Quercus petraea and Q. robur natural populations in Turkey. Canonical discriminant analysis (CDA) and principal component analysis (PCA) showed that 3 out of 15 studied leaf morphological characters (clustered hairs, number of intercalary veins, petiole length) mainly accounted for the discrimination between species. In accordance with earlier observations, the mean genetic differentiation between Q. petraea and Q. robur at 8 microsatellite loci (F_{ST} = 0.030) and at chloroplast microsatellites (G_{ST} = …
Sexual Phenotype Of Capparis Herbacea (Capparaceae), Nana Shakarishvili, Liana Osishvili
Sexual Phenotype Of Capparis Herbacea (Capparaceae), Nana Shakarishvili, Liana Osishvili
Turkish Journal of Botany
Floral morphology coupled with the morphometry of androecium revealed that Capparis herbacea Willd. has an andromonoecious sexual system, producing both male and perfect flowers on the same plant. Functionally male flowers develop more stamens with larger anthers than bisexual ones (63.6 ± 0.6 and 4.1 ± 0.01 mm; 58.1 ± 0.7 and 3.6 ± 0.02 mm, respectively). The ratio of male to perfect flowers ranges from 0.5 to 2.6 during the flowering season. The development of dense trichomes on the adaxial surface of the cavity made by variegated connate petals is presumably adaptive and serves to protect nectary exudate from …

Turkish Journal of Botany
Anatolia hosts 14 of the 22 taxa of genus Galanthus L. The phylogenetic relationships of Galanthus species were explored using DNA sequence data from both nuclear and chloroplast DNA of 70 specimens covering all subdivisions of Galanthus present in Turkey. Our data showed that species of the same geography clustered together phylogenetically, in contrast to the presently recognized taxonomy based on morphological characters. The 5.8S rRNA sequence data by itself is sufficiently informative for constructing phylogenetic trees. Our data confirm the identity of Galanthus koenenianus as a new taxon, well separated from G. alpinus; both are clustered within subseries Viridifolii, …

Turkish Journal of Botany
Morphological revision and phylogenetic analysis of Stachys L. sect. Eriostomum (Hoffmanns. & Link) Dumort. (Lamiaceae) based on nuclear ribosomal internal transcribed spacer (nrITS) sequences were conducted. Morphological analysis confirmed the previous arrangements of 3 subsections, i.e. Germanicae R.Bhattacharjee, Creticae R.Bhattacharjee, and Spectabiles R.Bhattacharjee, while suggesting some status changes and new records that were also confirmed by the phylogenetic analysis. The phylogenetic analysis suggested, however, some arrangements different from those indicated by morphology. Two subsections, i.e. Creticae and Germanicae-Spectabiles, instead of 3 were observed in the phylogenetic tree. The tree also suggested that 9 Stachys cretica L. subspecies form a polyphyletic …
