Magnetic fluids improving effect in in vitro regenerates in hypogravity conditions

Abstract

The previous in vitro experiments done with different types of magnetic fluids (MFs) pointed out the favorable effect upon dedifferentiation and redifferentiation. Finally, regeneration of an embryo and of plantlets from a single vegetative plant cell was successfully performed. The two processes are the most spectacular aspects of development involving the formation of different distinct cells and of tissue which increase the potential for variability to new conditions. These advancements generated the idea that the MFs could have a favorable effect on cell morphology and tissue structural organization. This study addressed the question of whether or not Magnetic Fluids could have a protective effect on plants grown under different stress conditions as well as in simulated hypogravity influence. In simulated hypogravity two possible patterns of influence were postulated: reversible and irreversible cell modifications. The presence of the magnetic particles (MPs) in the growth medium improved the cell and the anatomical leaf structure. The favorable effect was the enrichment of the density, due to MPs penetration in cytoplasm, or due to the change in the cell water potential. We presume both.
