Barley (Hordeum vulgare) is an economically important species, which can be cultivated in environmentally adverse conditions due to its higher tolerance in contrast to other cereal crops. The draft of H. vulgare genome is available already for couple of years; however its functional annotation is still incomplete. All available databases were searched to expand current annotation. The improved annotation was used to describe processes and genes regulated in transgenic lines showing higher tolerance to drought in our associated article, doi:10.1016/j.nbt.2016.01.010 (Vojta et al., 2016) [1]. Here we present whole transcriptome response, using extended annotation, to severe drought stress and subsequent re-watering in wild-type barley plants in stem elongation phase of growth. Up- and down-regulated genes fall into distinct GO categories and these enriched by stress and revitalization are highlighted. Transcriptomic data were evaluated separately for root and aerial tissues. Keywords: Barley, Drought stress, Genome annotation, Re-watering, Transcriptomics
