Screening of damage induced by lead (Pb) in rye (Secale cereale L.) – a genetic and physiological approach

İlhan DOĞAN

The fields in which lead (Pb) finds application in the modern world have increased dramatically in recent years. As a consequence of this intensive utilization of Pb, its toxicity tends to pose more and more environmental problems. The aim of this study was to evaluate the genotoxic potential of Pb and to characterize some physiological parameters in Secale cereale under Pb stress. Plants were subjected to different exposure levels of Pb (0, 100, 200 and 400 µmol/L) for two weeks. At the end of the experimental period, the effects of Pb exposure on the photosynthetic pigments content (chloroph ...Daha fazlası

Comparative analyses of phytochelatin synthase (PCS) genes in higher plants

İbrahim İlker ÖZYİĞİT

Plants employ various defence strategies to ameliorate the effects of heavy metal exposures, leading to re-establishment of metal homeostasis. One of the strategies includes the biosynthesis of main heavy metal detoxifying peptides phytochelatins (PCs) by phytochelatin synthase (PCS). In the present study, 14 PCS homologues were identified in the genomes of 10 selected plants. The size of these PCSs was 452-545 amino acid residues, with characteristic phytochelatin and phytochelatin_C domains. The N-terminal site of the proteins is highly conserved, whereas the C-terminal site is less conserve ...Daha fazlası
