“…Tombusviruses infect a wide range of annual crops, woody perennials, vines, ornamentals and cacti in the Mediterranean area and in different countries of the American and European continents (Martelli, 1981). Recently isolates have been obtained from apple and pear in the German Democratic Republic (Kegler & Schimanski, 1982), and from lettuce in Czechoslovakia (Novak. Novakova & Lanzova,198 1).…”

SUMMARY Tomato bushy stunt virus (TBSV) of unknown source was isolated from water of the River Thames, near Oxford. The isolate designated TBSV‐T was mechanically transmissible to several tomato (Lycopersicon esculentum) cvs and to other species including Petunia hybrida, pepper (Capsicum annuum). eggplant (Solanum melongena), Nicotiana clevelandii, Chenopodium amaranticolor and C. quinoa in which it caused systemic symptoms. It caused no infection of globe artichoke (Cynara scolymus) or Pelargonium domesticum. The virus was not adsorbed to soil and could be isolated from leachate of soil in which systemically‐infected tomato or C. quinoa plants were grown. Tomato plants became infected when grown in soil watered with virus suspensions. TBSV‐T was infective after 10 min at 80°C but not at 90°C and when diluted to 10‐5 but not to 10‐6. Purified virus preparations contained C. 30 nm isometric particles. In gel‐diffusion serological tests, TBSV‐T reacted with homologous anti‐serum and with antiserum to petunia asteroid mosaic virus but not to pelargonium leaf curl virus. Seed‐borne infection (50–65%) of TBSV was demonstrated in plants grown from seed of symptomlessly‐infected tomato fruit. TBSV was isolated from symptomlessly‐infected tomato fruit imported from Morocco during October‐April 1981. One of the isolates (TBSV‐M) was indistinguishable from TBSV‐T in host range, symptomatology and serological reactions. TBSV was also found in tomato plants growing extraneously in primary settlement beds at sewage works; such plants having been derived from undigested seeds in sewage. Because of its ‘alimentary‐resistance’ in man, it is possible that one ecological route whereby TBSV enters rivers is by man's consumption of TBSV‐infected tomatoes and eventual sewage dispersal into rivers.

“…possible source of infection in orchards is through the use of infected cherry seedlings or root suckers as rootstocks. Seed transmission has been reported for TBSV in apple (Allen, 1969;Kegler & Schimanski, 1982), pepper and tomato (Cherif, 1981;Tomlinson & Faithfull, 1984). PeAMV has been recovered from pollen (Allen & Davidson, 1967;NovBk, 1968; of infected cherry trees but it is not clear whether the virus is present within or on the surface of the pollen grains.…”

“…In our study we found a similarly high infection rate in seeds taken from fruits with symptoms of viral twig necrosis; however, the percentage of germination was very low in seed from damaged fruits and the 33 seedlings obtained were not infected. Kegler & Schimanski (1982) investigated 378 seedlings obtained from PeAMV-infected sweet cherry trees and did not detect any seed transmission.…”

Grafting symptomless scions, derived from petunia asteroid mosaic virus (PeAMV)-infected trees, to healthy rootstocks resulted in only 3.3% infection in the resulting trees. Up to 90% of seeds from infected sweet cherries contained high quantities of PeAMV, but the virus was not transmitted to the seedlings apparently because of low virus content in the embryo and loss of infectivity during seed maturation and storage. Replanting healthy cherry trees cv. Sam, grafted to different rootstocks, into contaminated soils resulted in new infections. Eight of 13 trees on rootstocks derived from Prunus auium (F 12/1 and cv. Sam on its own roots) were infected with PeAMV within a period of four years but only one of 16 trees on Weiroot-rootstocks (selections from Prunus cerasus) became infected. The detection of PeAMV in naturally contaminated soil samples by the bait plant procedure, using Nicotiana cleuelandii, was superior to testing soil eluates by enzyme-linked immunosorbent assay (ELISA) and immuno electron microscopy (IEM). Wild plants may contribute to virus propagation and maintenance of virus contamination of the soil as 25 of 310 samples from 712 herbaceous plants growing in the vicinity of infected trees contained PeAMV; the contaminated samples represented 12 species. The perpetuation of PeAMV by infected scion wood is probably of minor significance, and infection via the soil probably represents the most important means of spread of viral twig necrosis in northern Bavaria.
