2.2. Genomic DNA extraction and PCR
Genomic DNA was isolated from young leaves with DNeasy
Plant Mini Kit (Qiagen, 2006). PCR was performed in a reaction volume
of 10L in BioRad iCycler thermocycler. The components of
the reaction mixture were 20 ng of template DNA, 0.6UofWTB-Taq
polymerase (WestTeam Biotech, Pécs), 0.1mM dNTP mix, 0.75M
of each forward and reverse primer, and 1.25mMMgCl2 in 1× PCR
buffer.
