    , we have used a deep sequencing approach to generate a genome-wide transcriptome of foxtail millet after exposure to simulated drought stress. A large number of differentially expressed genesgenesSubject Category: Miscellaneous

    were characterized; in particular, we examined the roles of small interfering RNAs (siRNAs) and long noncoding RNAs (lncRNAs) in response to a water-deficit condition. These RNAs have remained largely unexplored in previous studies of stress-induced transcriptomes. We found that the reduced levels of 24-nt siRNA flanking genes were associated, for the most part, with proximal up-regulated genes, indicating a potential effect of 24-nt siRNAs on drought-regulated gene expressiongene expressionSubject Category: Miscellaneous

    . Several lncRNAs that responded to the simulated drought stress were also identified, and we found that one of them shared sequence conservationconservationSubject Category: Miscellaneous

    and colinearity with its counterpart in sorghum (Sorghum bicolorsorghum bicolorSubject Category: Organism Names

    ). Our findings provide new insights into drought-induced changes in the foxtail millet transcriptome.
