Toxicological Evaluation Of Polar And Nonpolar Components Of Isodon Coetsa (Lamiaceae), Sandhya Vincent Neelamkavil, John Ernest Thoppil
Turkish Journal of Botany
Isodon coetsa (Buch.-Ham. ex D.Don) Kudo, a perennial herb used in traditional Chinese folk medicines as an antibacterial, antiinflammatory, and antitumour agent, was subjected to toxicity analysis. Cytotoxic screening using the Allium L. assay was done with extracts containing polar and nonpolar compounds as well as with polar compounds alone. Root tips were treated with different concentrations of both the extracts, 0.005%, 0.01%, 0.05%, and 0.1%, for varying time durations (30 min, 1 h, 2 h, and 3 h). Extremely significant levels of chromosome abnormality (P < 0.001) were observed with the extracts when compared with the positive control (0.01% methyl parathion), but the extract with polar and nonpolar compounds showed higher abnormality percentage. Not much variation was observed in the mitotic index when compared to the negative control (distilled water). Studies revealed many clastogenic and nonclastogenic abnormalities. The major abnormalities included chromosome fragments, stickiness, ring chromosomes, chromosome bridges, pulverization, binucleate cell, micronucleus, ball metaphase, chromosome laggards, and shift in microtubule organizing center. The results showed that the nonpolar components possessed more clastogenic activity, which can be specifically targeted in order to destroy cancer cells. The toxic activity of extracts also suggests the need of judicious use of I. coetsa in folk medicines.

Contrasting Inbreeding Depression In Early And Late Stages Of The Life Cycle Of A Mediterranean Shrub, Anagyris Foetida (Leguminosae), Francisco Javier Valtueña, Josefa López, Ana Ortega-Olivencia, Tomás Rodriguez-Riaño, Miguel González
Turkish Journal of Botany
Anagyris foetida L. has a Mediterranean distribution, but its populations are highly fragmented. This, together with its mixed mating system, puts it at clear risk of being strongly affected by inbreeding depression. To determine the effect of inbreeding depression in this species, hand pollinations were performed during the 2003/04 season in 2 populations from SW Spain to generate selfed and outcrossed seeds. These seeds were divided in 2 sample lots and seedlings were obtained in different years. During the first year of life the first lot showed no differences in vegetative parameters between the 2 populations, so that no differentiation …

Chilling Tolerance Of Cicer Arietinum Lines Evaluated By Photosystem Ii And Antioxidant Activities, Özlem Turan, Yasemi̇n Ekmekçi̇
Turkish Journal of Botany
Two chickpea (Cicer arietinum L.) lines (AKN 87 and AKN 290) that have different chilling susceptibilities were exposed to 2 chilling temperatures (4 and 2 °C), either cold-acclimated (10 °C) or nonacclimated (25 °C), in order to understand and compare physiological and biochemical changes at the vegetative stage. Chilling temperatures resulted in reduced growth parameters, particularly in cold-acclimated lines, whereas nonacclimated plants exhibited the lowest water contents. Cold acclimation treatment led to protective changes of increased flavonoid, proline, and antioxidant enzyme activities, mostly superoxide dismutase (SOD) and ascorbate peroxidase (APX), in the lines. However, the 10 °C treatment did not …

Turkish Journal of Botany
The extreme morphological variations and unclear boundaries between varieties can lead to the misleading identification of Ficus deltoidea Jack (Moraceae) varieties. This has encouraged many taxonomists and botanists to study the variation within F. deltoidea. Thus, correct identification of F. deltoidea varieties is important, as several morphological and anatomical characters are variety-specific. The present study aims to evaluate the morphology and anatomy of leaf in 7 varieties of F. deltoidea, namely var. deltoidea, var. angustifolia, var. trengganuensis, var. bilobata, var. intermedia, var. kunstleri, and var. motleyana.

Comparative Analysis Of Hexaploid Avena Species Using Remap And Issr Methods, Edyta Paczos Grzeda, Piotr Tomasz Bednarek
Turkish Journal of Botany
Taxonomic relationships in Avena genus are not evident. Avena sativa L. might have originated either from Avena sterilis L. or Avena fatua L. Alternatively, it may have evolved independently during formation of the hexaploid form. A. fatua may have a different A genome than the other hexaploids. Studies performed with Ty1-copia retrotransposon probes demonstrated that this retrotransposon is present at low copy number in the C genome, while it is abundant in A, B, and D. The observed differences provide an opportunity for analyzing the putative origin of A. fatua as well as its relationships with other hexaploids. Two marker …
