  1. 1. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Bubaraye Ohiosimuan Dirikumo; [2023]
    Keywords : Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

    Abstract : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

  4. 3. Potassium channel AtTPK5 : An essential or redundant regulator of photosynthesis in Arabidopsis?

    University essay from Institutionen för fysik, kemi och biologi

    Author : Behrad Shiki Baluch; [2011]
    Keywords : Chloroplast; thylakoid; TPK; PCR; ETR; O2-evolution; PAR; PSII.;

    Abstract : It has previously been stated that K+-ions in a plant cell have a counter-balancing role in which the efflux of K+-ions from the thylakoid lumen charge-balance the light-induced proton pumping that is known to occur across the thylakoid membrane, and this in turn stabilizes photosynthetic activity. In the present study, two different types of plants of the same ecotype (Col-0) of Arabidopsis thaliana have been studied: a wild-type and a T-DNA exon-mutant (tpk5-e) that has lost the expression of the protein known as Tandem-pore K+- channel (AtTPK5).

  5. 4. Impact of Arbuscular Mycorrhiza symbiosis on photosynthesis in Medicago truncatula

    University essay from Molekylär genetik; Tekniska högskolan

    Author : Dhanunjaya Reddy Mettupalli; [2011]
    Keywords : Arbuscular Mycorrhiza; Medicago truncatula; ETR;

    Abstract : The Arbuscular mycorrhiza (AM) symbiosis is a mutual association formed by plant roots and soil fungi. Most vascular flowering plants have the ability to form AM associations, which show significant impact on ecosystem function and plant health. This association is based on the mutual exchange of nutrients between plant and fungus. READ MORE
