A. Levi et al., PRODUCTION OF RELIABLE RANDOMLY AMPLIFIED POLYMORPHIC DNA (RAPD) MARKERS FROM DNA OF WOODY-PLANTS, HortScience, 28(12), 1993, pp. 1188-1190
A procedure for identifying reproducible RAPD markers from woody plant
DNA is presented. The procedure relies on using a PCR buffer that con
tains 1 % Triton-X-100 and 0.1% gelatin [previously described for succ
essful polymerase chain reaction (PCR) amplification of 16S/23S rRNA i
ntergenic spacer regions from eubacteria], and amplification condition
s of 50 cycles: 30 sec at 94C, 70 sec at 48C, and 120 sec at 72C. The
combination of this buffer and these conditions amplified consistent f
ragments in higher amounts, as compared to other standard PCR buffers
and conditions generally used for RAPD analysis. This procedure result
ed in reliable RAPD patterns for all organisms tested. Chemical name u
sed: utyl)phenyl]-omega-hydroxypoly(oxy-1,2-ethanediyl) (Triton-X-100)
