Cellular and molecular-genetic mechanisms of symbiosis and associative interaction of microorganisms with plants in rhizosphere

Abstract

The review contains the results of research on symbiotic and associative interaction of microorganisms and plants in rhizosphere. A special attention is given to the process of contact association of microorganisms and plants tissues including the concrete molecular structures and dominant role pertaining to protein-carbohydrate interaction. There are common features and distinctions at formation of arbuscular mycorhiza, rhizobia– legume symbiosis and association of non-leguminous plants with Azospirillu

Glutathione Status in the Roots of Tomato Plants Transgenic by Genes psl and rapA1 in the Presence of Rhizobium leguminosarum

“…In 2 days after inoculation of control and transgenic tomato plants with R. leguminosarum, strain VSy3 (GFP), it was found that the quantity of bacteria in the rhizosphere in terms of dry biomass of the roots was 193.5 ± 38.7 CFU/g × 10 6 for plants transgenic by gene psl and 69.1 ± 13.82 CFU/g × 10 6 for plants transformed with gene rapA1. This figure was 21.6 ± 4.32 CFU/g × 10 6 on the roots of control plants (Fig.…”

“…Presence of rhizobia and penetration of bacteria into plant cells within a framework of symbiosis modify polarization of the plasma membrane, cytoskeleton of root hairs, metabolism of auxins, and accumulation of reactive oxygen species [6]. In plant cells involved in formation of nodules, glutathione and its analog characteristic of the family Fabaceae (homoglutathione) are accumulated.…”
