Abstract Experiments were carried out to evaluate the reaction of cabbage cultivars to mechanical inoculation with selected isolates of the turnip mosaic virus (TuMV). Simultaneously we aimed for the assessment of TuMV pathogenicity towards cultivars chosen to be transformed in order to obtain the resistance trait. The TuMV-CAR37A and TuMV-CAR39 isolates from horseradish proved to be infective towards ‘Amager’ and ‘Langedijker’ B. oleracea subsp. capitata f. alba. The course of symptom expression was assessed and the results of virus detection in symptomless leaves, using DAS-ELISA, were documented. Both tested cultivars showed a similar level of susceptibility. TuMV-CAR37A and TuMV-CAR39 can be useful in the selection of cabbage lines with resistance to the turnip mosaic virus.

In recent years, the accumulated molecular data of Turnip mosaic virus (TuMV) isolates from various hosts originating from different parts of the world considerably helped to understand the genetic complexity and evolutionary history of the virus. In this work, four complete TuMV genomes (HC9, PK1, MS04, MS15) were characterised from naturally infected cultivated and wild-growing Papaver spp., hosts from which only very scarce data were available previously. Phylogenetic analyses showed the affiliation of Slovak Papaver isolates to the world-B and basal-B groups. The PK1 isolate showed a novel intra-lineage recombination pattern, further confirming the important role of recombination in the shaping of TuMV genetic diversity. Biological assays indicated that the intensity of symptoms in experimentally inoculated oilseed poppy are correlated to TuMV accumulation level in leaves. This is the first report of TuMV in poppy plants in Slovakia.

Internal Necrosis

Experiments over two growing seasons clearly showed that Turnip mosaic virus (TuMV) infection was associated with internal necrosis (sunken necrotic spots 5 to 10 mm in diameter) and Beet western yellows virus (BWYV) infection was associated with collapse of leaf tissue at the margins (tipburn) in heads of stored white cabbage (Brassica oleracea var. capitata). Virtually no tipburn was seen in cv. Polinius, whereas cv. Impala was affected severely. Internal necrotic spots were seen in both cultivars. BWYV appeared to interact with TuMV. Plants infected with both viruses showed a lower incidence of external symptoms and had less internal necrosis than plants infected with TuMV alone. Cauliflower mosaic virus (CaMV) did not induce significant amounts of internal necrosis or tipburn, but did, in most cases, exacerbate symptoms caused by TuMV and BWYV. BWYV-induced tipburn worsened significantly during storage. Post-transplanting inoculation with TuMV induced more internal necrosis than pre-transplant inoculation. There was a significant association between detection of TuMV just prior to harvest and subsequent development of internal necrotic spots. Individually, all three viruses significantly reduced the yield of cv. Polinius, whereas only BWYV and CaMV treatments reduced the yield of cv. Impala.

Cowpea aphid-borne mosaic virus (CABMV) is a potyvirus that causes the most serious virus disease of passion fruit crops in Brazil. It is transmitted by several species of aphids in a non-persistent, non-circulative manner. The reaction of 16 species of Passiflora to infection by mechanical inoculation with four Brazilian isolates of CABMV was evaluated under greenhouse conditions. Only P. suberosa, a wild species, was resistant to infection by all virus isolates, in two independent assays. P. suberosa grafted onto infected P. edulis f. flavicarpa did not develop symptoms; neither was the virus detected by RT-PCR in the upper leaves, suggesting that this species is immune to CABMV.

Two virus cultures, RC4 and YC5, were isolated in Taiwan from calla lily (Zantedeschia spp.) cv. Black magic displaying yellow spot and stripe on leaves. Both isolates were mechanically transmitted to various hybrids of Zantedeschia and induced systemic symptoms similar to those observed on diseased Black magic. In addition to Zantedeschia spp., the two virus isolates also infected several cruciferous species and induced mosaic symptoms. Electron microscopy revealed the presence of flexuous virus particles about 750 nm in length. The two isolates were propagated in and purified from mustard plants and were used as immunogens for production of antisera in rabbits. In enzyme-linked immunosorbent assay and sodium dodecyl sulfate-immunodiffusion tests, both antisera reacted strongly with their homologous antigens and with antigens of two Turnip mosaic virus (TuMV) isolates from radish (TuMV-R) and lisianthus (TuMV-L), but not with 21 other different potyviruses tested. In reciprocal tests, antisera against TuMV-R and TuMV-L also reacted strongly with RC4 and YC5 antigens, indicating that these two calla lily isolates are serologically indistinguishable from other known TuMV strains. Cloning and sequence analyses confirmed that both isolates shared 95 to 99% of deduced amino acid sequence identities in the coat protein genes with those of various known TuMV strains. This investigation represents the first record of the natural infection of TuMV in calla lily.
