Expression analysis of <i>PtrANR1</i> and <i>PtrLAR1</i> in <i>P. trichocarpa</i> tissues.

<p>(A) Semi-quantitative RT-PCR analysis of <i>PtrANR1</i> and <i>PtrLAR1</i> expression in various tissues of <i>P. trichocarpa</i>. (B) Quantitative real-time PCR analysis of <i>PtrANR1</i> transcript levels in various tissues of <i>P. trichocarpa.</i> (C) Quantitative real-time PCR analysis of <i>PtrLAR1</i> transcript levels in various tissues of <i>P. trichocarpa</i>. Poplar <i>18S</i> expression was used as a control. Total RNA was isolated from roots (R), stems (S), petioles (P), mature leaves (ML), and young leaves (YL).
