  • The application of MANOVA to analyse Arabidopsis thaliana metabolomic data from factorially designed experiments 
    Johnson, Helen E.; Smith, Aileen R.; Mur, Luis A. J.; Causton, David R.; Lloyd, Amanda J. (2007-06-16)
    Metabolomic technologies produce complex multivariate datasets and researchers are faced with the daunting task of extracting information from these data. Principal component analysis (PCA) has been widely applied in the ...
  • Measuring the metabolome: current analytical technologies 
    Dunn, Warwick B.; Johnson, Helen E.; Bailey, N. J. C. (2005-03-04)
    The post-genomics era has brought with it ever increasing demands to observe and characterise variation within biological systems. This variation has been studied at the genomic (gene function), proteomic (protein regulation) ...
  • Metabolic fingerprinting of salt-stressed tomatoes 
    Smith, Aileen R.; Goodacre, Royston; Johnson, Helen E.; Broadhurst, David I. (2003-03-01)
    The aim of this study was to adopt the approach of metabolic fingerprinting through the use of Fourier transform infrared (FT-IR) spectroscopy and chemometrics to study the effect of salinity on tomato fruit. Two varieties ...
