Abstract

In banana and plantain (Musa spp.) production areas in Venezuela plants were observed with foliar symptoms of a virus-like disease characterized by chlorotic streaks which often become progressively necrotic. In samples of the cultivars Pineo gigante (AAA) and Mysore (AAB), the banana streak virus (BSV) was detected by immunosorbent electron microscopy. Four virus isolates were identified by immunocapture followed by polymerase chain reaction amplification (IC-PCR) using isolate-specific oligonucleotide primers of two BSV strains. The results of IC-PCR indicated that the isolates occurring in the samples were BSV-OL. This strain is known to be integrated in the host genome (Musa) and there is evidence that BSV infection can arise from these integrated sequences. BSV was detected in the Venezuelan states of Aragua, Barinas, Carabobo, Delta Amacuro, Mérida, Miranda, Sucre, Yaracuy and Zulia.
