EFFECT OF TRANSGENES ON MEIOTIC RECOMBINATION IN HIGHER EUCARYOTES BY THE EXAMPLE OF TOMATO

Z.R. Yunusov¹, A.A. Solov'ev², S.N. Mikhailenko¹, R.A. Komakhin³, A.A. Zhuchenko⁴

The experimental data are presented about effect of transgenes, maize Ds-element and R480 gene, determining to plants the resistance to tomato bronze spot virus, on some stages of meiosis and the frequency of meiotic recombination (rf)among progeny of heterozygous tomato plants. 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.

Key words: tomato, meiotic recombination, meiosis, transgenes.
