[The role of peptidyl-prolyl-Cis/trans-isomerase Genes of Arabidopsis thaliana in plant defense during the course of Xanthomonas campestris infection].

Experimental data obtained in this study showed the involvement of A. thaliana immunophilin genes At2g16600, At4g33060, and At5g48570 in plant defense responses to the Xanthomonas campestris invasion. We found not only that the expression levels of these genes changed upon bacterial infection, but also that the plant's resistance to the pathogen was increased if the expression levels of the immunophilin genes were elevated in the host cells.

[Experimental models of transgenic plants promising for the modern technologies].

Transgenic popato plants have been created which express recombinant proteins, analogues of spidroin 1, the protein of the cobweb skeleton thread. Expression of the hybrid spidroin 1 genes possessing some repeated sequences retains both in the model test-tube-growing plants and in the crops. Expression level of the synthetic spidroin 1 genes and the level of accumulation of their products in plants depend on the type of promoter, number of repeats, organ specificity and plant species but not on the duration of plant material storage.
