Ilex paraguariensis is a subtropical tree cultivated in south of Brazil, northeast of Argentina, and east of Paraguay. The occurrence of drought episodes during the active phase of the annual growth cycle leads with leaf abscission and yield reduction. RNA-seq, gas chromatography-mass spectrometry, and spectrometry assays were used to elucidate a global understanding of how roots respond to dehydration. A total of 190,474 unigenes and 265,309 transcripts were obtained from 74,911,111 pair-ends reads (2x100bp) from 6 libraries. Among them, 30.6% were associated with a Gene Ontology (GO) term. The comparative analysis of transcriptomes between the control and each stressed sample revealed that 8,046 transcripts were differentially expressed [DETs, FDR
