Susceptibility Of Different Lentil ( Lens Culinaris Medik.) Cultivars Toagrobacterium Tumefaciens (Smith & Townsend) Conn, Aziz Karakaya, Sebahattin Özcan
Turkish Journal of Botany
Agrobacterium tumefaciens (Smith& Townsend) Conn is commonly used in gene transfer to plants. The effectiveness of bacterial strains and suitable plant genotypes facilitate this process. In this study, 8 lentil cultivars grown in Turkey were assessed for their susceptibility to two wild-type A. tumefaciens strains, A281 and A136NC. Both strains induced tumors in lentil cultivars, while differing in the ability to form tumors. Although most of the cultivars had some degree of susceptibility to A. tumefaciens infection, cultivars Yesil 21 and Pul 11 had higher frequencies of tumor formation in both strains than the other cultivars tested.

A New Record For The Marine Algal Flora Of Turkey: Caulerpa Scalpelliformis (Brown Exturner) C. Agardh ( Caluerpaceae, Chlorophyceae), Ö. Osman Ertan, İsmail İ. Turna, Mario Cormaci
Turkish Journal of Botany
The first record of C. scalpelliformis (Brown ex Turner) C. Agardh from Antalya harbour (36°53'.1 N, 030°42'.2 E) is reported here. The species was found in the year 1995, in the period August-September, when seawater temperature reached 26.5 to 27°C. After this time, the species seemed to disappear, probably because of low winter temperatures. Thus, the occurrence of this species in Antalya harbour should be considered temporary, not as an indication of the expansion of the distribution area of this lessepsian species in the Mediterranean Sea.

Development Of An Efficient Plant Regeneration System In Sunflower(Helianthus Annuus L.), Ekrem Gürel, Kemal Kazan
Development Of An Efficient Plant Regeneration System In Sunflower(Helianthus Annuus L.), Ekrem Gürel, Kemal Kazan
Turkish Journal of Botany
With the aim of developing an efficient plant regeneration system from cells or tissues of sunflower ( Helianthus annuus L.), we compared several regeneration protocols using different explant types and hormonal combinations. Somatic embryogenesis could be induced on cotyledon explants, especially from the basal (proximal) portion of the cotyledons, but genotypic vairation appeared to be the most critical factor for both somatic embryo and root production. Such a variation was more prominent when 10 different sunflower cultivars were compared for shoot production from shoot-tip explants. Further refinement of the culture conditions may be neceassary to improve the efficiency of somatic …

Effects Of Salt Stress Of The Respiratory Components Of Some Plants, N.A. Kasumov, Z.I. Abbasova, G. Gündüz
Turkish Journal of Botany
Oxygen absorption, kinetic regularities of free radical oxidation and anti-oxidation activity were studied in roots and isolated mitochondria for various groups of plants under salt stress of NaCl, Na 2 SO 4 and Na 2 CO 3 . The results show that spearation of oxidation and phosphorylation obviously stimulates the oxygen absorption by plants under salt strees. Therefore, the anti-oxidation activity of roots decreases abruptly, resulting in an uncontrolled acceleration of free radical processes. The obtained data is a definite contribution to the concept concerning the toxic effect of salt on plants.
