초록

Water-deficiency is one of the most serious challenges which restrict crop production. Root is the primary tissues exposed to water limitation in soil. Although a number of transcriptome data under water limitation have been produced in rice, but most of them have analyzed the effect of leaf or shoot. Thus, understanding of relating molecular mechanism is still limited. To get global view of the effect on water deficiency in rice root, we carried out RNA-Seq experiment. To do this, we compared the RNA-Seq transcriptome data of 3 day samples under water deficiency with those of unstressed rice roots with unstressed control. As a result, we identified 1,098 genes upregulated in water stress condition for 3 days. Gene ontology (GO) enrichment analysis revealed that 18 GO terms are overrepresented. Of them, valyl-tRNA aminoacylation, transcription from RNA polymerase II promoter, glycine catabolic process, and L-phenylalanine catabolic process are more significant, indicating that transcription of new transcripts, control of translation fidelity, and reuse of primary and secondary metabolites can be activated during water stress.
