  • Ougham, Helen J.; Donnison, Iain S.; Taylor, J.; Vozel, B.; Chehdi, K.; Gay, Alan P.; Wagstaff, Carol; Stead, A. D.; Cariou, C.; Rogers, H. J. (2006)
    Hyperspectral imaging is a technique with an increasing range of applications in plant science. Here we present some case studies showing its application to a number of areas of plant stress. In the first case we will ...
  • King, Ian P.; King, Julie; Armstead, Ian P.; Harper, John A.; Roberts, Luned A.; Thomas, Howard; Ougham, Helen J.; Jones, R. Neil; Thomas, Ann M.; Moore, Beverley J. (2005)
    Lolium perenne/Festuca pratensis hybrids and their derivatives provide an ideal system for intergeneric introgression. The work described in this paper enables the elucidation of gene organization along Lolium/Festuca ...
  • Jones, R. Neil; Ougham, Helen J.; Thomas, Howard; Pasakinskiene, Izolda S. (2009-09)
    This paper is an update of our earlier review (Jones et al., 1997, Markers and mapping: we are all geneticists now. New Phytologist 137: 165–177), which dealt with the genetics of mapping, in terms of recombination as the ...
  • Thomas, Ann M.; Thomas, Howard; Armstead, Ian P.; King, Ian P.; Harper, John A.; Moore, Beverley J.; Huang, Lin S.; Fentem, Philip Anthony; Ougham, Helen J.; Jones, R. Neil; Jones, T. A. H.; Roberts, Luned A.; King, Julie; Donnison, Iain S. (2005-05-01)
    Intergeneric hybrids between Lolium multiflorum and Festuca pratensis (Lm/Fp) and their derivatives exhibit a unique combination of genetic and cytogenetic characteristics: chromosomes undergo a high frequency of homoeologous ...
  • Ougham, Helen J.; Latipova, Galina; Valentine, John (1996-09-01)
    The dominant gene N-1 in cultivated oats gives rise to a phenotype characterized by a thin papery lemma from which the grain readily threshes free, a multiflorous habit, and rachillas that are elongated in comparison to ...
  • Chew, Yin Hoon; Wenden, Benedicte; Flis, Anna; Mengin, Virginie; Taylor, Jasper; Davey, Christopher L.; Tindal, Christopher; Thomas, Howard; Ougham, Helen J.; De Reffye, Philippe; Stitt, Mark; Williams, Mathew; Muetzelfeldt, Robert; Halliday, Karen J.; Millar, Andrew J. (2014-09-30)
    Understanding how dynamic molecular networks affect whole-organism physiology, analogous to mapping genotype to phenotype, remains a key challenge in biology. Quantitative models that represent processes at multiple scales ...
  • Ougham, Helen J.; Millar, Andrew; Muetzelfeldt, Robert; Tindal, Christopher; Thomas, Howard; Davey, Chris (2009-06)
    Plant systems biologists have developed many mathematical models at the organ, cell and molecular scales. There is now a need to be able to incorporate these models into existing plant/crop models in order to access their ...
  • Thomas, Howard; Ougham, Helen J.; Hortensteiner, Stefan (2001)
    Chlorophyll (chl) catabolism occurs throughout the plant life cycle, in germination, vegetative growth and reproductive development. It is highly sensitive to the environment, varying markedly with the season and in response ...
  • Schaberg, P. G.; Archetti, Marco; Lev-Yadun, [No Value]; Manetas, [No Value]; S, Y.; Leather, S. R.; Ougham, Helen J.; Hughes, N. M.; Lee, D. W.; Doring, T. F.; Hagen, S. B.; Thomas, Howard (2009-03-25)
    Ultraviolet (UV) vision, first discovered in ants more than a century ago, is a major area of interest for behavioural ecology. Because, unlike humans, many animal species can see UV light, spectrometry in the UV has ...
  • Armstead, Ian P.; Huang, Lin S.; King, Julie; Ougham, Helen J.; Thomas, Howard; King, Ian P. (2007-08-20)
    Background Various methods have been developed to explore inter-genomic relationships among plant species. Here, we present a sequence similarity analysis based upon comparison of transcript-assembly and methylation-filtered ...
  • Doring, T. F.; Lev-Yadun, S.; Ougham, Helen J.; Leather, S. R.; Schaberg, P. G.; Archetti, Marco; Manetas, Y.; Thomas, Howard; Lee, D. W.; Hagen, S. B.; Hughes, N. M. (2009-03-01)
    Leaf colour change is commonly observed in temperate deciduous forests in autumn. This is not simply a side effect of leaf senescence, and, in the past decade, several hypotheses have emerged to explain the evolution of ...
  • Ougham, Helen J.; Canter, Peter H.; Donnison, Iain S.; Thomas, Howard (2002)
    Leaf senescence has an important role in the plant’s nitrogen economy. Chlorophyll catabolism is a visible symptom of protein mobilization. Genetic and environmental factors that interfere with yellowing tend to modify ...
