Endophytic microorganisms of potato (Solanum tuberosum L.): biodiversity, functions and biotechnological potential

Endophytic communities represent a fascinating inner world of the plants. Endophytes are found in all plant species studied, though the number of microbial cells and their species diversity can differ a lot. The potato (Solanum tuberosum L.) is economically important staple food crop, and the induction of plant resistance to various infections as well as the search for the effective eco-friendly preparations could provide higher potato yields and are very promising for modern agriculture. In this review, we focus on the biodiversity of the potato endophytes and the aspects of their functional importance and possible application in the biological control of plant pathogens. We have systematized literature data regarding the prevention of the harmful effect of pathogenic fungi, bacteria, viruses, and insects resulting from the vital activity of the endophytic microorganisms within the potato plants.
