Molecular phylogenetic analysis of Olea europaea L. subsp. europaea cultivars grown in the Marmara region, Turkey
(Univ Kebangsaan Malaysia, 2013)DNA markers based on the PCR techniques are being broadly utilized during the past two decades. Randomly Amplified Polymorphic DNA (RAPD) is one of these techniques employed for determining the polymorphisms. In this study, ... -
Threatening factors on plant diversity of Kazdaği (Ida mountain) national park in Turkey and suggestions for conservation
(Taylor & Francis Ltd, 2009)Kazdagi National Park is located in the Southern part of Marmara region in the North-west of Turkey. There are about 800 taxa naturally grown in the National Park and 79 of them are endemic to Turkey. Also, thirty one of ... -
Multiple GUS expression patterns of a single Arabidopsis gene
(Wiley-Blackwell Publishing, 2009)Ten independent transposant lines with gene or enhancer traps (ET) inserted into the same gene (At2g01170) were identified in Arabidopsis thaliana. Transposon insertions were confirmed for each line. Only three of five ET ... -
Morphologic structuring between populations of chub mackerel Scomber japonicus in the Black, Marmara, Aegean, and northeastern Mediterranean Seas
(Springer Tokyo, 2009)Morphometric and meristic analyses of chub mackerel Scomber japonicus were used to discriminate stocks throughout the Black, Marmara, Aegean, and northeastern Mediterranean Seas. Morphometric and meristic analyses showed ... -
Isolation, molecular characterization and functional analysis of OeMT2, an olive metallothionein with a bioremediation potential
(Springer Heidelberg, 2015)Metallothioneins are essential in plants for metal detoxification in addition to their other roles in plant life cycle. This study reports the characterization of an olive (Olea europaea L. cv. Ayvalik) metallothionein ... -
Carbonic anhydrase inhibitors: Inhibition of the β-class enzyme from the yeast Saccharomyces cerevisiae with sulfonamides and sulfamates
(Pergamon-Elsevier Science Ltd, 2009)The protein encoded by the Nce103 gene of Saccharomyces cerevisiae, a beta-carbonic anhydrase ( CA, EC 4.2.1.1) designated as scCA, has been cloned, purified, characterized kinetically and investigated for its inhibition ... -
Effects of cypermethrin exposed to host on the developmental biology of pimpla turionellae (Hymenoptera: Ichneumonidae)
(Oxford Univ Press Inc, 2009)We investigated egg-to-adult developmental time, adult longevity, adult body size, and wing and antenna length of Pimpla turionellae (L.) (Hymenoptera: Ichneumonidae) reared on Galleria mellonella L. (Lepidoptera: Pyralidae) ... -
Carbonic anhydrase activators: Activation of the β-carbonic anhydrase Nce103 from the yeast Saccharomyces cerevisiae with amines and amino acids
(Pergamon-Elsevier Science Ltd, 2009)The protein encoded by the Nce103 gene of Saccharomyces cerevisiae, a beta-carbonic anhydrase (CA, EC 4.2.1.1) designated as scCA, was investigated for its activation with amines and amino acids. scCA was poorly activated ... -
BAT1, a bidirectional amino acid transporter in Arabidopsis
(Springer, 2009)The Arabidopsis thaliana At2g01170 gene is annotated as a putative gamma amino butyric acid (GABA) permease based on its sequence similarity to a yeast GABA transporting gene (UGA4). A cDNA of At2g01170 was expressed in ... -
