In the microbial-plant system "bacteria Sphingomonas sp. K1B - plants pea» investigated intercomponent molecular signaling, regulated ethylene synthesis in plants by the bacterial phytohormones and slowing the root development rate. The channels of signal transmission in biosystem are protected from external influences by receptor control, which transmits a signal to the plant only when the coincidence of secondary structures (conformations) reagents by scheme "lock-key". However, the conformation of signaling molecules and receptors can varied under the influence of the rotating magnetic field. Resonant magnetic exposure can reorient the magnetic spins of the atoms, which entails a change in the conformation molecules and the obstruction signals of the control receptor, which is a lock of clear-channel signal.

In the current study, the plants pea were grown on the hydroponically. The chemical composition of a sterilized nutrient solution are (mg/l): Ca(NO3)2 × 4H2O (100mM) – 0.6; K2HPO4 × 3H2O (600mM) – 0.6; MgSO4 × 7H2O (400mM) – 0.6; CaCl2 × 2H2O (100mM) – 0.6; KCl (400mM) – 0.6; KNO3 (1M) – 0.6; FeC4H4O6 × 2.5H2O (2mM) – 6.0; micronutrients. In control variant №1 plants were grown without external influences. In a variant №2 and №4 in nutrient solution were introduced bacteria Sphingomonas sp. K1B. In an embodiment №3 №4 and pea plants together with vessels were placed (one minute per day) in a rotating magnetic field.

The experiment showed, that a weight of pea roots embodiments №1 and №4 were close, and in embodiments №1 and №3 differ significantly. This proves that a rotating magnetic field leads to a clear-blocking signaling between bacteria and plants in variant №3. Perhaps, in this version of the experiment under a magnetic field was changed the secondary structure of the signaling molecules and the signaling channel is blocked at the stage of receptor control.

Thus, the effect of the rotating magnetic fields on the signal channels in the plant-microbe systems can block dialogue between phytopathogens and plant, which can reduce the level of bacterial diseases.
