ABSTRACT

The model system based on the sugar beet calluses infected by mycoplasms (mollicutes) was elaborated, and changes in the callus cells morphology under the effect of these microorganisms were also studied. The calluses of sugar beet 3K51 cultivated on the Gamborg medium were infected by phytopathogenic mollicute Acholaplasma laidlawii var. granulum str.118. Under the effect of mollicute infection one could observe changes in the cell morphology of sugar beet calluses: the plant cells were transformed from round to lengthened, the intensity of polyploids forming was increased, their grouping and their total destruction were observed. Data of electron microscopy confirm the presence of the mollicute in the sugar beet calluses: acholeplasma cells were localized between and within undifferentiated plant cells.

ABSTRACT

Sampling irradiation of spacesuit "Orlan-M" allowed construction of a simulation model of the spacesuit shielding function for critical body organs. The critical organs self-shielding model is a Russian standard anthropomorphic phantom. Radiation protective quality of the spacesuit was assessed by calculating the dose attenuation rates for several critical body organs of an ISS crewmember implementing EVA. These calculations are intended for more accurate assessment of radiation risk to the ISS crews donning "Orlan-M" in near-Earth orbits.
