Seasonal Distribution Of Phytoplankton In Orduzu Dam Lake (Malatya, Turkey), Ahmet Kadri̇ Çeti̇n, Bülent Şen Jan 2004

Seasonal Distribution Of Phytoplankton In Orduzu Dam Lake (Malatya, Turkey), Ahmet Kadri̇ Çeti̇n, Bülent Şen

Turkish Journal of Botany

The species composition and seasonal distribution of phytoplankton in Orduzu Dam Lake was studied for a year. Diatoms (Bacillariophyta) were most diverse, followed by green algae (Chlorophyta), blue-green algae (Cyanophyta), euglenoids (Euglenophyta) and dinoflagellates (Dinophyta). A total of 117 taxa were recorded and the phytoplankton of the lake contained a large number of detached benthic algae. Phytoplankton assemblages were dominated by diatoms in all the periods investigated and centric diatoms were the most abundant. Overall phytoplankton density was high during the spring and summer months and the highest phytoplankton density was observed in August. The abundance of phytoplankton was positively …

Effect Of Thidiazuron On Shoot Regeneration From Different Explants Of Lentil (Lens Culinaris Medik.) Via Organogenesis, Khalid Mahmood Khawar, Cengi̇z Sancak, Serkan Uranbey, Sebahatti̇n Özcan Jan 2004

Effect Of Thidiazuron On Shoot Regeneration From Different Explants Of Lentil (Lens Culinaris Medik.) Via Organogenesis, Khalid Mahmood Khawar, Cengi̇z Sancak, Serkan Uranbey, Sebahatti̇n Özcan

Turkish Journal of Botany

Thidiazuron (TDZ) is among the most active cytokinin like substances and induces greater in vitro shoot proliferation than many other cytokinins in many plant species. Leaf, stem, stem node and cotyledonary node explants of 2 extensively cultivated Turkish lentil cultivars, Ali Dayı and Kayı 91, were cultured on Murashige and Skoog (MS) media supplemented with various concentrations of TDZ. The present study was conducted to develop a rapid and efficient shoot regeneration system suitable for the transformation of lentil (Lens culinaris Medik.) using TDZ. Cotyledonary nodes and stem nodes after the initial callus stage regenerated prolific adventitious shoots via organogenesis. …

Phylogeny And Biogeography Of Wajira (Leguminosae): A Monophyletic Segregate Of Vigna Centered In The Horn Of Africa Region, Mats Thulin, Matt Lavin, Remy Pasquet, Alfonso Delgado-Salinas Jan 2004

Phylogeny And Biogeography Of Wajira (Leguminosae): A Monophyletic Segregate Of Vigna Centered In The Horn Of Africa Region, Mats Thulin, Matt Lavin, Remy Pasquet, Alfonso Delgado-Salinas

All Peer-Reviewed Publications

Evidence from chloroplast trnK and nuclear ribosomal ITS sequences and morphological data reveals that the monotypic legume genus Wajira is nested within a clade comprising the species of Vigna subgen. Macrorhynchus. This Wajira-containing clade is basally branching in a larger clade that contains many of the genera traditionally referred to as tribe Phaseoleae subtribe Phaseolinae. Wajira is thus recircumscribed to include Vigna subgen. Macrorhynchus. Given the heterogeneity of floral morphology of its constituent species, Wajira is apomorphically diagnosed by woody stems and a pollen brush that comprises an introrse linear array of unicellular hairs. This recircumscribed genus now comprises five …
