    Blastocystis is an important parasite that infects humans and a wide range of animals like rats, birds, reptiles, etc. infecting a sum of 60% of world population. It belongs to the Stramenopiles, a Heterologous group that ...
  • The biochemical consequences of ascorbate deficiency in Arabidopsis thaliana 

    Sultana, Nighat (University of ExeterBiosciences, 2011-12-20)
    Biochemical consequences of ascorbate deficiency were studied in the leaf tissue of Arabidopsis thaliana ascorbate-deficient vtc mutants with a view of understanding the relationship between ascorbate, stress response and ...
  • Bioclimatic envelope model of climate change impacts on blanket peatland distribution in Great Britain
