posted on 2011-02-28, 01:25 authored by Juan Du, Eriko Miura, Marcel Robischon, Ciera Martinez, Andrew GrooverRelative expression of PCN and paralog Pt-ATHB.11 in apices, leaves, roots, and stem was determined using Quantitative Real Time PCR (QRT-PCR) of two month old tissue culture grown Populus tremula x alba. PCN and paralog Pt-ATHB.11 are expressed in all tissues assayed, and are highly expressed in shoot apexes and stem tissue with active cambium. Stem tissue samples were confirmed to have a vascular cambium by phloroglucinol staining of secondary xylem. Relative expression (Mean ± SE) was calculated from triplicate QRT-PCR reactions of independent RNA samples prepared from different trees.
