Interaction between Cowpea Aphid-Borne Mosaic Virus Isolates and Its Effect on Passion Fruit Woodiness Disease on Passiflora edulis Sims and Passiflora ligularis Juss

Figure 1

PCR amplification products of CABMV; 1, 2, 3, and 4 are the first four seedlings testing negative for CABMV. Negative control (−) is a sample from disease-free seedlings. Band size was compared with a 1 kb ladder (L). The positive control (+) formed a band at 650 bp, which is the expected size for CABMV. It was obtained from diseased plant maintained in a screen house. All the seedlings tested showed similar results.
