Selected products of DNA amplification were cloned into a plasmid
vector by using the TOPO TA Cloning Kit Dual Promoter (with pCR
II-TOPO vector) with One Shot TOPO10F’ Chemically Competent
Escherichia coli (Invitrogen). DNA sequencing was conducted commercially
in the Laboratory of DNA Sequencing and Oligonucleotide
Synthesis, Institute of Biochemistry and Biophysics of the Polish
Academy of Sciences (Warsaw, Poland).
