Comparison of the root tip transcriptome of 2 pearl millet lines with contrasted primary root growth

We analysed global gene expression in the primary root tip of 2 pearl millet (Pennisetum glaucum) inbred lines with high (line 249) and low (line 337) primary root growth using RNAseq. The objective was to identify genes potentially associated with changes in root growth. Two pearl millet lines with contrasted root soil aggregation were grown in hydropony for 15 days. 3 biological replicates were produced per line. RNA was extracted from the primary root tip (2 cm apex). RNA-seq was performed by the Montpellier GenomiX Platform (MGX, https://www.mgx.cnrs.fr/). Sequencing was performed on an Illumina HiSeq 2500.
