Fig. 2From: Identification of high-copy number long terminal repeat retrotransposons and their expansion in Phalaenopsis orchidsSlot Blot showed the percentage of the LTR (a, c) and CDS (b, d) sequences of Orchid-rt1 (a, b) and Gypsy1 (c, d), and the LTR sequences of Gypsy2 (e) and Gypsy3 (f) within the genomic DNA of P. equestris, P. aphrodite, P. violacea, and P. belllina. A 10 ng of plasmid DNA containing the LTR sequences and 1 μg genomic DNA were performed for serial dilution and hybridized with the probes of PeAct9 and these LTR sequences. Arrowheads indicate the similar intensity of hybridized slots between the plasmid DNA and genomic DNABack to article page
