Other claims from this paper (17)
- Observation Disease incidence in symptomatic bean fields ranged from 10 to 50%.
- Observation Symptomatic bean plants had green or yellow mosaic, blisters, and leaf distortion.
- Observation Severe stunting accompanied prevalent disease in some bean locations.
- Observation BCMV, CMV, BYMV and ClYVV occurred in the majority of symptomatic bean samples.
- Observation Three symptomatic bean samples tested positive for Peanut stunt virus.
- Association Peanut stunt virus positive bean samples came from fields where stunting was prevalent.
- Intervention effect Sap inoculation with PSV infected samples caused local chlorotic lesions in Chenopodium amaranticolor.
- Intervention effect Sap inoculation with PSV infected samples caused leaf distortion in Nicotiana benthamiana.
- Intervention effect Mechanical inoculation of PSV isolates caused systemic chlorotic lesions and rings in Pinto bean plants.
- Intervention effect Mechanical inoculation of PSV isolates caused local chlorotic lesions and later systemic chlorotic lesions in Chenopodium quinoa.
- Intervention effect Mechanical inoculation of PSV isolates caused local necrotic lesions in Chenopodium murale.
- Observation All three PSV coat protein isolates yielded RT PCR amplicons of the expected 651 bp size.
- Method / resource Sequencing the bean associated amplicons confirmed PSV identification.
- Method / resource Sequences of the bean associated PSV isolates were deposited as MG256178 through MG256180.
- Observation Phylogenetic analysis placed all three Bulgarian PSV isolates in Western subgroup II.
- Observation The authors identify this as the first report of PSV in Bulgaria and the second report of the Western strain in Europe.
- Recommendation The authors propose monitoring natural hosts to clarify PSV epidemiology in Eastern Europe.
