AB  - Although high mobility group B (HMGB) proteins have been identified from a 
      variety of plant species, their importance and functional roles in plant 
      responses to changing environmental conditions are largely unknown. Here, we 
      investigated the functional roles of a CsHMGB isolated from cucumber (Cucumis 
      sativus L.) in plant responses to environmental stimuli. Under normal growth 
      conditions or when subjected to cold stress, no differences in plant growth were 
      found between the wild-type and transgenic Arabidopsis thaliana overexpressing 
      CsHMGB. By contrast, the transgenic Arabidopsis plants displayed retarded 
      germination compared with the wild-type plants when grown under high salt or 
      dehydration stress conditions. Germination of the transgenic plants was delayed 
      by the addition of abscisic acid (ABA), implying that CsHMGB affects germination 
      through an ABA-dependent way. The expression of CsHMGB had affected only the 
      germination stage, and CsHMGB did not affect the seedling growth of the 
      transgenic plants under the stress conditions. The transcript levels of several 
      germination-responsive genes were modulated by the expression of CsHMGB in 
      Arabidopsis. Taken together, these results suggest that ectopic expression of a 
      CsHMGB in Arabidopsis modulates the expression of several germination-responsive 
      genes, and thereby affects the germination of Arabidopsis plants under different 
      stress conditions.
