From: Genome-wide analysis of root hair-preferential genes in rice
Identification of genes preferentially expressed in rice root hairs. a Seedling at 3 DAG, prior to sample preparation. Scale bar = 5 mm. b Microscopic observation of root hairs. Scale bar = 0.1 μm. c RT-PCR analysis of samples using 2 marker genes: OsBOR1, negative marker showing root-preferential expression; and OsEXPA17, positive control showing root hair-specific expression. Value in parentheses indicates number of PCR cycles. d Heatmap analysis of 409 genes preferentially expressed in root hairs. Yellow, high expression; dark-blue, low expression
