Abstract. Xerophytic plants are used to combat desertification and restore degraded territories in Southern Russia, for example, one of the most common is Teresken gray (Krascheninnikovia ceratoides (L.) Gueldenst.). The stability of this plant is associated not only with its species specificity, but also with the presence of endophytic mycorrhiza, which includes arbuscular endomycorrhiza fungi (AMF). The formation of AMF in plants contributes to increased resistance to adverse environmental factors, in particular drought. In this regard, the aim of the work was to search for the possible presence of AMF in the root system of K. ceratoides. To achieve this goal, morphological research methods were used, with the help of which mycorrhization and AMF formation were evaluated using the Etching method. The research results revealed elements inherent in both endophytic mycorrhiza and representatives of AMF in K. ceratoides. The intensity of colonization of the root system by endophytic mycorrhiza was 37 %. The number of identified AMF elements was 18 %, and the number in mycorrhizal root fragments was about 3 %. The data obtained indicate that there is most likely a symbiotic relationship between endophytic fungi, including AMF and K. ceratoides, which may contribute to its resistance to adverse environmental factors. This fact may be of interest for further research aimed at selecting groups of endophytic fungi that increase plant resistance to drought
