title: Root control - Biological replicate 1 -  Technical replicate 2
design: RNA-Seq was done using total RNA from three biological replicates and two technical replicates for control and treated (drought) roots and leaves samples. Only RNA samples with the RIN above or equal to 6.5 and a 25S:18S ratio above or equal to 1 were selected for sequencing. Library preparation and paired-end sequencing were performed at BGI (Beijing Genomics Institute) using the TruSeq RNA Library Prep Kit v2 (Illumina, catalogue number RS-122-2001) according to the manufacturer`s instructions and starting with 1 g of RNA material. Sequencing was performed with the Illumina Sequencing Machine HiSeq4000 (PE100).
