Mapping Gene Activity of Arabidopsis Root Hairs

We provide an atlas of gene and protein expression in Arabidopsis root hair cells, generated by paired-end RNA-seq and LC/MS-MS analysis from protoplasts that carry the root hair-specific pEXP7-GFP reporter construct. In total, transcripts from 23,234 genes were detected in root hairs; those related to cell wall biosynthesis and translation differed most dramatically in abundance when compared to non-GFP root protoplasts.
