1. Mutagenesis in wheat: An approach to make saline green!
Abstract : The raising salinity in the soils around the world have been widely studied during the last decades due to the massive loss in agricultural land. Today, nearly 8% of the world’s arable land can no longer be used for crop cultivation due to salt contaminations, and more than half of the countries in the world are affected. READ MORE

2. Heavy metal contamination and toxicity : Studies of Macroalgae from the Tanzanian Coast
Abstract : Concentrations of various metals are elevated above background levels in several intertidal areas along the Tanzanian coasts. However, there is little available information concerning the toxicity of these metals and how the uptake of these metals by bioindicators are influenced by external factors, such as heavy rains and increased coastal eutrophication, which tend to fluctuate.

4. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi
Abstract : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. READ MORE

5. Metal accumulation by plants : evaluation of the use of plants in stormwater treatment
Abstract : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. READ MORE
