Metabolic response of Lolium Perenne to drought stress

摘要

Under the predicted climate change scenarios plant growth will be increasingly affected by drought stress.A better understanding of biochemical and physiological responses on drought stress is necessary to design grasses capable of withstanding these climate perturbations.Despite response to drought stress is a complex process of multigenic nature, little is known about the whole‐system response of biochemical reactions.Metabolomics is a useful approach to reflect the dynamic response of such metabolic networks to environmental changes ( Nikiforova et al., 2005 ).The aim of our work was to use metabolic profiling to get insight in the response of Lolium perenne on drought stress.As grasses are often infected with fungal endophytes, Neoty phodium lolii/ L.perenne associations were involved in our study to elucidate endophyte‐induced changes in the response to drought.
