“…TSWV has extremely broad host range (more than 1,000 plant species), including vegetables, ornamental plants, and weed plants as well [1,2], and is transmitted by various thrips species in a propagative persistent manner [3,4]. The most effective control against this pathogen seemed to be the production of resistant cultivars.…”

Resurgence of Tomato spotted wilt virus (TSWV) worldwide as well as in Hungary causing heavy economic losses directed the attention to the factors contributing to the outbreak of this serious epidemics. The introgression of Tsw resistance gene into various pepper cultivars seemed to solve TSWV control, but widely used resistant pepper cultivars bearing the same, unique resistance locus evoked the rapid emergence of resistancebreaking (RB) TSWV strains. In Hungary, the sporadic appearance of RB strains in pepper-producing region was first observed in 2010-2011, but in 2012 it was detected frequently. Previously, the non-structural protein (NSs) encoded by small RNA (S RNA) of TSWV was verified as the avirulence factor for Tsw resistance, therefore we analyzed the S RNA of the Hungarian RB and wild type (WT) isolates and compared to previously analyzed TSWV strains with RB properties from different geographical origins. Phylogenetic analysis demonstrated that the different RB strains had the closest relationship with the local WT isolates and there is no conserved mutation present in all the NSs genes of RB isolates from different geographical origins. According to these results, we concluded that the RB isolates evolved separately in geographic point of view, and also according to the RB mechanism.

Iris yellow spot virus (IYSV), an emerging disease of onion crops, was identified by transmission electron microscopy, enzyme linked immunosorbent assay, and reverse transcription polymerase chain reaction in Costa Rica. Onion plants had straw-colored, elongated lesions and tip dieback. Costa Rican IYSV nucleocapsid partial sequences (15 isolates) grouped with isolates from North and Central America and from New Zealand.

“…Seedlings, transplanted in field, were monitored biweekly and the number of plants showing typical virus disease symptoms was recorded as percentage disease incidence of different types of virus diseases for plants treated with the IMP and the existing management methods. Types of virus diseases and disease incidence were identified based on the typical symptoms shown by respective virus diseases according to disease diagnosis manuals and descriptions of previous studies (Whitfield et al, 2005;Chen et al, 2010;Samarakoon et al, 2012). The tomato plants remained as asymptomatic at the time of observation were designated as healthy plants.…”
