The evidence of increased crossing over rate in tomato hybrids infected with TAV (Tomato aspermy virus), PVX (Potato virus
X), TMV (Tobacco mosaic virus), TMV+PVX indicates the recombinogenic effect of viral infection. Cytological studies of the
early diakinesis in healthy and virus-infected tomato revealed significant changes in chiasma number and position. The most
significant changes were established for bivalents with two interstitial chiasmata and with one terminal and one interstitial.
The data obtained indicate redistribution of the chiasmata position and induction of additional exchanges. The virus-induced
recombination is segment-specific and depends on the host plant genotype, virus infection and the interaction between them. 相似文献
