Вариабельность вирусов в экосистемах

Viruses variability in ecosystems

Nonspecific aphid-virus vector species were registered. The virus carrier ability for five species has been detected for the first time. The transition of many pathological complexes to parasitic on unusual the plant host and expansion of their spectrum is shown. The tendency to increase nonspecific viruses and vectors involved in the host parasitic relationships were found. Demonstrated that nonspecific vectors induced changes composition parasitic complexes and biological characteristics of viruses. Transfer factors is importance in viruses biodiversity.
