Histology Of Somatic Embryogenesis In Cultured Leaf Explants Of Pistachio(Pistacia Veral), Ahmet Onay Jan 2000

Histology Of Somatic Embryogenesis In Cultured Leaf Explants Of Pistachio(Pistacia Veral), Ahmet Onay

Turkish Journal of Botany

The histology of somatic embryo initiation and development in pistachio ( Pistacia were L.) embryogenic masses (EMS) derived from leaf explants was examined using light microscopy. Explants with somatic embryos at different developmental stages were fixed for histological examination, cut into 10 µm thick sections, stained with hematoxylin-eosin and observed microscopically. The histological examination showed that the two types of cell clusters induced originated from explants and were morphologically different. These results clearly demonstrate that the induction and development of somatic embryos from leaf explants of pistachio were from single epidermal or subepidermal cells.

Turkish Journal of Botany

The adventive root tip cells of a bulbous plant, Sternbergia lutea (L.) Ker-Gawl. ex Sprengel (Amaryllidaceae), were examined by LM (light microscope) and EM (electron microscope). At the meristematic area of the root tips, which was 1 mm in length, two types of cell were observed: meristematic cells and Ca-oxalate raphide crystal idioblasts. Ca-oxalate raphide crystal idioblasts were observed to lie in two lines between the inner and outer ground meristems. Some similarities and some differences were found between those cells in their ultrastructure. It was seen that the membrane thickness of crystal idioblasts and meristematic cells were the same. …

Peroxidase And Iaa-Oxidase Activities During Rooting In Cuttings Of Threepoplar Species, Tohi̇t Güneş

Turkish Journal of Botany

Peroxidase (PO: E. C 1.11.1.7) and IAA. Oxidase (IAA-O) enzyme activities were investigated during rooting in cuttings of Populus nigra L., Populus alba L. and Populus tremula L. ( Salicaceae), and the relations between enzyme activities and rooting ability were examined comparatively. PO activity started to increase the early stages of primordium formation and reached the highest level before root emergence. However, no apparent correlation was found between the activity of PO and the ability of the cuttings to form roots. IAA-O activity was observed only in root cuttings of P. alba and P. nigra. Activity increased after day 6 …

Protoplast Isolation In Lupin ( Lupinus Mutabilis Sweet): Determination Of Optimum Explant Sources And Isolation Conditions, Mehmet Babaoğlu Jan 2000

Protoplast Isolation In Lupin ( Lupinus Mutabilis Sweet): Determination Of Optimum Explant Sources And Isolation Conditions, Mehmet Babaoğlu

Turkish Journal of Botany

Effects of cultural factors on the yield, viability and division of protoplasts were investigated in Lupinus mutabilis Sweet containing a high protein content as well as a reasonable oil content which may make this species an alternative crop to soybean in Turkey. Explants from different in vitro seedling parts were evaluated on the suitability of protoplast isolation and viability. Leaf mesophyll was the most suitable tissue as a protoplast source. Pectinases as well as cellulases were essential for the isolation of protoplasts. Nine percent (w/v) mannitol was suitable to stabilise osmotic pressure together with low salt concentrations in washing and …

Reduction Of Lignin In Tobacco Through The Expression Of An Antisense Caffeic Acid O-Methyltransferase, Ti̇jen Talas Oğraş, Kemal Kazan, Nermi̇n Gözükirmizi Jan 2000

Reduction Of Lignin In Tobacco Through The Expression Of An Antisense Caffeic Acid O-Methyltransferase, Ti̇jen Talas Oğraş, Kemal Kazan, Nermi̇n Gözükirmizi

Turkish Journal of Botany

Caffeic acid O-methyltransferase (COMT) is a methylation enzyme involved in the early stages of lignin biosynthesis. To examine the effect of antisense expression of a heterologous COMT gene on lignification, an antisense construct of a cDNA encoding a caffeic acid O-methyltransferase ( pOMT8) from Stylosanthes humilis Humb., Bonpl. & Kunth Fabaceae was transferred into tobacco via Agrobacterium tumefaciens. A large number of kanamycin-resistant shoots were recovered after transformation, and randomly selected putative transgenics were analysed for stable integration of the transgene into their genomes. The analyses demonstrated that antisense expression of pOMT8 resulted in reductions in total COMT activity, which …

Ecological Wood Anatomy Of Turkish Rhododendron L. (Ericaceae). Intraspecific Variation, Nesi̇me Merev, Hakki Yavuz

Turkish Journal of Botany

The intraspecific relationships of selected wood anatomical characters such as altitude, stem diameter, stem age and average annual ring width were investigated in five different Turkish Rhododendron L. species. Rhododendron luteumSweet. grows at an altitude of 110 to 2230 m, R. ungerniiTrautv. 900 to 2020 m, R. smirnoviiTrautv. 1600 to 2230 m, R. caucasicumPallas 1900 to 3100 m, and R. ponticumL. from sea level to 2230 m in the Eastern Black Sea Region. Although the degree of significance varies between species, correlation and multiple regression analysis indicated a significant correlation between wood anatomical characters and non-anatomical factors.

Robinia Pseudo-Acacia L. As A Posssible Biomonitor Of Heavy Metal Pollution In Kayseri, Ahmet Aksoy, Uğur Şahi̇n, Fati̇h Duman

Turkish Journal of Botany

The leaves of Robinia pseudo-acacia L. (Fabaceae) were tested as a possible biomonitor of heavy metal pollution in Kayseri. Concentrations of Pb, Cd, Cu and Zn were determined in unwashed and washed leaves and soils collected from a wide range of sites with different degrees of metal pollution. Differences between the unwashed and washed samples varied according to the metal pollutant levels. Significant correlations were obtained between the heavy metal concentrations in surface soil and washed leaf samples. R. pseudo-acacia was found to be a useful biomonitor of the heavy metals investigated.
