A larger proportion of the fixed carbon is retained as starch in the leaf in short days, providing a larger store to support metabolism and carbon export during the long night. The mechanisms that facilitate this adjustment of the sink-source balance are unknown. Starchless pgm mutants were analysed to discover responses that are triggered when diurnal(More)
Oxidative stress is one aspect of metal toxicity. Zinc, although unable to perform univalent oxido-reduction reactions, can induce the oxidative damage of cellular components and alter antioxidative systems. Verbascum thapsus L. plants that were grown hydroponically were exposed to 1 and 5 mM Zn²+. Reactive oxygen species (ROS) accumulation was demonstrated(More)
Influence of edaphic factors and metal content on diversity of Trichoderma species at 14 different soil sampling locations, on two depths, was examined. Forty-one Trichoderma isolates from 14 sampling sites were determined as nine species based on their internal transcribed spacer (ITS) sequences. Our results indicate that weakly alkaline soils are rich(More)
In this paper, we have studied the interdependence of seed yield per plant and the following morphophysiological traits: total leaf number per plant, total leaf area per plant, plant height, total seed number per head, head diameter, weight of 1,000 seeds and oil content. Path coefficient analysis was used to separate direct and indirect effects of studied(More)
The white rot fungus Phanerochaete chrysosporium has significant pollutant-degrading capabilities with its oxidoreductases. The lignin-degrading enzyme system of this fungus also allows the breakdown of different organic pollutants (xenobiotics). The most significant enzymes in these processes are the lignin peroxidase and the manganese peroxidase. In this(More)
The early fight-inducible proteins (ELIPs) are nuclear-encoded proteins localized in the chloroplasts and related to cab (light harvesting chlorophyll alb-binffmg) gene family. Light stress controls ELIP expression at different levels, at the level of transcription and the accumulation of the protein in the thylakoid membranes. The induction of ELIP(More)
The effect of different concentrations of lead was investigated in two different ways in the leaves of Helianthus annuus plants. In the first way, removed leaf discs from 5-wceks old plants were floated in 0.05, 0.25, 2.50 and 5.00 mM PbNO3 solutions for 2, 4 and 6 days. In addition, the chlorophyll content and the activity of peroxidase enzyme which are(More)
