“…When a plant is infected with a given virus strain, the plant may become protected agamst the effects of a subsequent inoculation with another strain of the same virus. This protection is caused by different types of interactions resulting in suppression of symptoms caused by the second (challenger) virus whose replication is often strongly inhibited or completely blocked (McKlNNEY 1929, PRICE 1940, HAMILTON 1980, BOZARTH and FoRD 1988.…”

An unusual type of interference between two strains of bean common mosaic virus, viz. NY15 and NL3, infecting bean plants, was investigatred. Wdhen a primary leaf was inoculated with NY15 as inducer and 1–8 days later, the opposite leaf with NL3 as challenger, the plant did not develop symptoms characteristic of NL3, i.e. systemic necrosis in the top, stem and wilting and withering of the youngest trifoloclate leaves. A7‐h interval between the inoculations with inducer and challenger already sufficed to reduce the number of plants showing NL3 symptoms. Surprisingly, the amount of NL3 in the challenge‐inoculated leaf was always than that in the singly infected control, Furthermore, NY15 could not be detected in the opposite leaf until 8 days post‐inoculation and appered enen later in that leaf when challenge‐inoculated. Histological studies showed that NL3 appered later in the xylem of bothe the petiole and stem between primary leaves and first trifoliolate leaf, as compared with the singly inoculated control. The results suggest that suppression of Nl3 symptoms by Ny15 is not caused by impeding its multiplication, but by delaying the transport of NL3 to the xylem of petiole and stem.

“…It is widely agreed that a plant infected with one virus usually retains its susceptibility to unrelated viruses, but is protected to some degree against different strains of the same virus ( 1,7,13) . Numerous exceptions to this generalization have been noted (1,13).…”

Cross-Protection Studies with Strains o f Concave G u m and Psorosis Virusesphenomena in sweet orange seedlings infected with various California strains of psorosis virus, including concave gum, were first reported by Wallace ( 16, 17), who pointed out that in some instances protection was only partial. The cross-protection or virusstrain-interference reaction has sometimes been useful in diagnosing psorosis in cases where leaves of sweet orange seedlings failed to show definitive symptoms.I n 1960 an indexing test in the quarantine greenhouse used for the University of California Citrus Variety Improvement Program (9, 10, 18) revealed a faint oak-leaf pattern on leaves of King mandarin (Citrus nobilis Loureiro) inoculated with budwood of PI (Plant Introduction, U. S. Department of Agriculture) 209532, a sweet orange [C. sinensis

“…In insects, where no antibodies seem to be formed to materials which are antigenic in vertebrates (Bernheimer et al, 1952), multiplication and maturation may go on for the whole life of the host. The same applies also to plants where no virus antibodies can be demonstrated (Price, 1940). This absence of viral antibodies may permit the continuous multiplication of the virus in plants and in vectors.…”
