From: Comprehensive Analysis of NAC Domain Transcription Factor Gene Family in Populus trichocarpa
Expression analysis of selected NAC genes using quantitative real-time RT-PCR (RT-qPCR). The relative mRNA abundance of 25 selected NAC genes was normalized with respect to reference gene UBQ10 in different tissues. The bars are standard deviations (SD) of three technical repeats. SA, shoot apices; L, leaf (4~6 internodes); Phl, phloem; DX, differentiating xylem; OR, old root; RT, root tip; C, cortex.
