The ability to grow plants in space self-perpetuating gardens is an actual for providing an advanced life support system for humans during extended missions. However, space factors affect expression of the genes regulated by the systems, sensing environmental signals. In space a risk of genetic rearrangements is increased, and some changes in bacterial DNA expected. As a consequence, bacteria may exhibit novel characters, e.g., pathogenicity. During the previous our experience we have determined an increase of internal colonization of the rice roots with bacteria in space flight. To understand the data and to predict acquisition of increased aggressiveness towards the plant-host by bacteria, molecular-genetic plant-bacteria interactions affected with physical factors will be simulated. Genes coding for bacterial pectinases provide a suitable model for studies of well-integrated objectives, concerning plant-bacteria interactions.
