First Report of <i>Tomato spotted wilt virus</i> in Tomatillo in Florida

Fig. 2. Detection of Tomato spotted wilt virus (TSWV) infection in tomatillo plants by reverse transcription-polymerase chain reaction (RT-PCR). Total RNA was extracted from leaves of non-symptomatic (NS; lane 1) and symptomatic (S; lanes 2 and 3) tomatillo, amplified by RT-PCR with tospovirus primers (gL3637 and gL4510, lanes 1 and 2; TSWV723 and TSWV722, lane 3), analyzed by native electrophoresis on a 2% agarose gel and stained with ethidium bromide. Lane 4 (M) contains markers with sizes in kilobases (kb) indicated to the right of the gel.
