Histological and morphological research of macro-and microsymbiote in stress conditions

Abstract

The purpose of the work was to study
the adaptable features and the stress factors infl uence
analysis on the growth and development of plant symbiotic
system - microorganisms Rhizobium trifolii and Trifolium
pratense. Ultra structure change symbiotic mechanism
under the infl uence of stress factors has been established.
We have found out that in the infected cell of root nodule
there are two organisms - prokaryote and eukaryote which
are under infl uence of senescence as a result of stressinducing
impact. It should be noted that their senescence
does not always proceed synchronously. Our experiments
also have shown that theperibacterial space becomes the
lytic compartment during the period of symbiotic system
senescence. Its activity is under plant cell control
