Transcripts and APase activities in the transgenic hairy roots.

<p>A) Transcripts of <i>PvPAPs</i> in the transgenic hairy roots. B) Internal APase activities; C) Root associated APase activities; Expression levels of <i>PvPAP1</i>, <i>PvPAP3</i>, <i>PvPAP4</i> and <i>PvPAP5</i> were normalized by their expression levels in the transgenic lines transformed with the empty vector, respectively. CK represents transgenic line transformed with the empty vector; OX-PvPAP1,3–5 means transgenic hairy roots with overexpressing <i>PvPAP1</i>, <i>PvPAP3</i>, <i>PvPAP4</i> and <i>PvPAP5</i>, respectively. Each bar is the mean of four biological replicates with standard error. Star symbols represent significant difference between the CK line and OX-PvPAP lines through student’s <i>t</i> test (<i>p</i><0.05).
