[The virus infection progression in potato plants in conditions of simulated microgravitation].

The influence of simulated microgravitation (clinostating) on the proceeding of mixed virus infection in Zhuravushka variety potato plants, infected with potato viruses X and M (PVX, PVM) was investigated. It was shown, that sensitivity of "virus-plant" system to microgravitation depends both on pathogene species and clinostating mode. Vertical clinostating was found to be more effective than horizontal one. By means of biotest, PCR and ELISA it was detected that potato plants, infected with PVX and PVM are released from PVX under the influence of clinostating during 19-47 days. Assume, that microgravitation is able to induce some protective reactions in plants that influence virus reproduction.
