Name: C100_Z1-2
Instrument: Illumina HiSeq 2000
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: RANDOM
Layout: PAIRED
Construction protocol: Uniformly sized seeds were selected, surface-sterilised, and grown under control (nutrient medium without additional NaCl) and salt-treated (nutrient medium supplemented with 100 mM NaCl) conditions as described in (Shelden et al. 2013). After three days of germination, seminal roots were dissected, collected into 1.5 mL tubes, immediately snap-frozen in liquid nitrogen, and then stored at -80°C. Samples were dissected in the following steps: A 1.5 mm long section marked Zone 1 (meristematic zone) was taken from the root tip. The second section (Zone 2) was dissected from the elongation zone up to the third section, Zone 3 (maturation zone), which was excised at the point of visible root hair elongation up to 3/4 of the entire root. Total RNA was isolated from 50 mg root tissue using the Qiagen RNeasy kit following the manufacturer’s protocol. The RNA was analyzed for quality and concentration using a DeNovix DS-11 spectrophotometer (Wilmington, DE, USA) and an Agilent Technologies 2100 Bioanalyzer. Libraries were amplified through 13 cycles of PCR using Illumina guidelines. The Illumina TruSeq RNA Sample preparation kit v2 (Illumina Inc.) was used according to the manufacturer’s protocol. Poly(A) enrichment was used.
