Phytobiomes in the technogenic environment

In the regions of mining and processing solid minerals, there is a tendency to increase man-made waste and increase the territories with accumulated environmental damage. As a result, unique plant communities are destroyed, rare species disappear. Their restoration is supposed to be carried out using the best modern technologies. At the same time, in undisturbed habitats, the relations of co-existence of plants with symbiont organisms were formed coevolutionarily. On the roots of orchids, gymnosperms, legumes and many other plants, specialized structures were formed - endo- and exomycorrhizae, rhizobial bacteroids, which provide the phytopartner with symbiotrophic nutrition. In the technogenic environment, the phenomenon of plant symbiosis with myco- and bacteriosymbionts is destroyed, its recovery is slow due to the lack of symbiont organisms in the root layer. The duration of symbiosis, myco-and bacteriotrophy of plants, is negatively affected by the presence of ecotoxicants, which cause premature aging of mycorrhizae and nodules, the development of a parasitic lifestyle of mycosymbionts. This article emphasizes the need for monitoring the state of symbiotrophic plants in forest plantations on recultivated waste, as well as early detection of signs of deterioration in the relationship between root cohabitants. The focus is on the multidisciplinary study of the ecology and the specifics of symbiosis, especially in rare plants, to accelerate the restoration of the diversity of symbioses.
