Brote Grande, A New Phytoplasma Associated Disease of Chile Peppers in the Desert Southwest

Fig. 4. Phytoplasma polymerase chain reaction products separated on a 1% agarose gel stained with ethidium bromide. Total DNA was extracted from healthy or symptomatic chile plants and tested for the presence of phytoplasma by PCR with the phytoplasma specific primers P1 and P7. Reactions were resolved on a 1% agarose gel that was visualized by ethidium bromide staining. Lane M contains the size standard (1 Kb plus DNA ladder, Invitrogen) with sizes of bands indicated at left. Lanes 1-42 are PCR reactions from extracted DNA from symptomatic chile plants. The arrow denotes the positive PCR band. Lanes (-) contain PCR reactions performed on DNA extracted from healthy chile plants.
