Poplar ANT is expressed in the cambium and is induced by cytokinins. Cross-section of a Poplar pAIL1:GUS stem following GUS assay (A) and qPCR analyses of PtANT and PtCYCD3;2 transcripts following treatments of cytokinin (100 nM 2iP) or mock treatments for one or twelve hours (B). Two individuals represented separately in adjacent bars were used for the experiment. Transcript levels were normalized to PttTUA2. Error bars: s.d. in four technical replicates.
