The effects of cold pretreatment, AgNO3 and activated charcoal on haploid plant production from unpollinated sugar beet ovules were investigated. Both cold pretreatment and the addition of charcoal increased the frequency of embryo formation, whereas AgNO3 decreased or completely inhibited it. Colchicine (50, 100, 150 or 500 mg l(-1)) and trifluralin (1.7, 3.4 or 5.0 mg l(-1)) for 12, 24, 36 or 48 h were compared in agar-solidified, agarose-solidified or liquid media. Although colchicine gave a higher doubling rate (25.3%) than trifluralin (18.2%), the difference was not significant. Both agents were more effective when used in liquid (29.1%) than agarose-solidified medium (20.7%) and agar-solidified medium (15.4%). A treatment duration of 48 h was significantly more effective (27.5%) than 12 h (13.6%) but it was not different from 24 h (16.3%) or 36 h (18.6%).

Extension of flower longevity in transgenic plants via antisense blockage of ethylene bıosynthesis Deçani Yol, Betul; Öktem, Hüseyin Avni; Department of Biotechnology (2004) Ethylene (C2H4) is a very simple molecule, a gas, and has numerous effects on the growth, development and storage life of many fruits, vegetables and ornamental crops. In higher plants, ethylene is produced from L-methionine in essentially all tissues and ACC Synthase and ACC Oxidase are the two key enzymes in the biosynthesis of ethylene. The objective of the present study was to transform tobacco (Nicotiana tabacum L. cv. Samsun) plant with partial sequence of torenia acc oxidase gene in antisense and sen...
Optimization of regeneration and agrobacterium mediated transformation of sugar beet (Beta vulgaris L.) Baloğlu, Mehmet Cengiz; Yücel, Ayşe Meral; Department of Biology (2005) In this study, optimization of a transformation and regeneration system via indirect and direct organogenesis in cotyledon, hypocotyl, petiole, leaf and shoot base tissues of sugar beet (Beta vulgaris L. cv. ELK 345 and 1195) was investigated. Two different germination, three different callus induction and shoot induction medium was used for indirect organogenesis of sugar beet cultivar ELK 345. Except cotyledon, other explants (hypocotyl, petiole and leaf) produced callus. However no shoot development was ...
Evaluation of photosynthetic performance of wheat cultivars exposed to boron toxicity by the JIP fluorescence test Oz, M. T.; TURAN, ÖZLEM; Kayihan, C.; EYİDOĞAN, FÜSUN; EKMEKÇİ, YASEMİN; YÜCEL, MUSTAFA; Öktem, Hüseyin Avni (Institute of Experimental Botany, 2014-12-01) The changes in growth and photosynthetic performance of two wheat (Triticum aestivum L.) cultivars (Bolal-2973 and Atay-85) differing in their sensitivity to boron (B) toxicity were investigated under toxic B conditions. Eight-day old seedlings were exposed to highly toxic B concentrations (5, 7.5, and 10 mM H3BO3) for 5 and 9 days. Fast chlorophyll a fluorescence kinetics was determined and analysed using JIP test. Growth parameters, tissue B contents, and membrane damage were measured at two stress durati...
Genetic transformation of lentil ( Lens culinaris m. cv.Sultan.1) with a transcription factor regulator (MBF1c) and analysis of transgenic plants Kamçı, Hamdi; Çelikkol Akçay, Ufuk; Kamçı, Hamdi; Department of Biotechnology (2011) Agrobacterium mediated genetic transformation of lentil Sultan 1 cultivar with MBF1c and evaluation of transgenic plants was aimed. The study was initially based on optimized protocol with Agrobacterium tumefaciens KYRT1 strain and pTJK136 binary plasmid. Based on this protocol and transient marker gene expression in embryo apex, 15% stable transformation efficiency was aimed. However limited knowledge about pTJK136 and problem with curing KYRT1 leaded us to use Agrobacterium tumefaciens C58C1 strain and al...
Biological hydrogen production from sugar beet molasses by agar immobilized R. capsulatus in a panel photobioreactor ELKAHLOUT, Kamal; SAĞIR, EMRAH; ALIPOUR, Siamak; Koku, Harun; Gündüz, Ufuk; EROĞLU, İNCİ; Yücel, Ayşe Meral (2018-03-18) Biohydrogen production from sugar beet molasses was investigated by using agar immobilized R. capsulatus YO3. A panel photobioreactor (1.4 L) was employed for a long-term hydrogen production in both indoor and outdoor conditions. The impact of several initial molasses concentrations on hydrogen production, yield and productivity were assessed. Indoor studies revealed that initial sucrose concentration in molasses should be kept below 20 mM to prevent inhibition of hydrogen production. The highest hydrogen p...
