Effect of transgenes on meiotic recombination in higher eucaryotes by the example of tomato

The experimental data are presented about effect of transgenes, maize Ds-element and R480 gene, on some stages of meiosis in F1 tomato plants and the frequency of meiotic recombination (rf) in their progeny. On the basis of own results and the data of literature the authors suggest and give prove the mechanism of transgenes local effect on crossingover between linked genes.
