Expression analysis of selected Populus CCCH genes using quantitative real-time RT-PCR (RT-qPCR). The relative mRNA abundance of 12 Populus CCCH genes was normalized with respect to reference gene UBQ10 in different tissues. The bars represent standard deviations (SD) from three technical repeats. RT, roots; ML, mature leaves (4 ~ 6 internodes from top); YL, young leaves (1 ~ 3 internodes); XL, differentiating xylems.
