Fig. 4. Agarose gel electrophoresis of DNA
products derived from amplification of RNAs
of four isolates of Turnip mosaic virus (TuMV)
with Potyvirus-specific degenerate primer by
reverse transcription-polymerase chain reac-
tion. Purified RNA from virus particles of YC5
and RC4 or total RNAs extracted from infected
tissues were used as templates for amplifi-
cation. Lane M is the molecular markers. Lane
H represents the total RNA purified from
uninfected mustard tissue.
