Figure 1 From:Expression of 5 S rRNA genes linked to 35 S rDNA in plants, their epigenetic modification and regulatory element divergence PCR analysis of 5 S organization.Schemes of separate(A)and linked(B)configuration of 5 S rDNA. Positions of primers are marked with arrowheads. The lines below indicate putative PCR products.(C)Analysis of separate organization using the 5SgF/5SgR primer pair. The arrow indicates position of the band extracted for subsequent cloning. Asterisk – position of a 5 S monomer (120 bp).(D)Analysis of linked organization using the 5SgF/26SPr1 primer pair. PCR products were separated in 1.2% agarose gels and detected by ethidium bromide fluorescence. Back to article page
