Expression of PdWND3A in various tissues and organs. Different tissues and organs were collected between 12:00 PM and 2:00 PM from three WV94 plants. Total RNAs were extracted from root, young leaf, mature leaf, young stem (internodes 1 to 3), mature stem (internodes 6 to 8), petiole of mature leaf, inner bark (bark of mature stem) and cambium layer (scrapped stem under bark of mature stem). The PdWND3A transcript level was measured by qRT-PCR. Shown are mean values of three biological replicates ± S.D.
