A variety of molecules of pathogenic origin, such as bacterial flagellin (flg22), are recognized by plants through plasma membrane receptors and induce both local and systemic immune responses. In this case, vesicular transport is key to ensuring a rapid and accurate response. When interacting with pathogens localized on the cell surface, immune receptors undergo endocytosis along the common endosomal pathway. Which vesicular pathway pathogens are used to penetrate tissues and the importance of flot1 in this process remains incompletely understood. This study is devoted to the influence of biotic stress factors on the immune response of wild type Arabidopsis thaliana plants and its knockout mutant Atflot1ko. The processes of endocytosis under the influence of various agents have been studied: 1-naphthaleneacetic acid and methyl-ß-cyclodextrin. Transmission electron microscopy revealed differences in cell responses to stress induced by flg22. It has been shown that biotic stress in knockout mutants activates the secretory pathway (exocytosis), which is necessary to protect cells from the actions of the pathogen on the cell surface, while endocytosis aimed at moving the pathogen into the vacuole is activated in wild-type plants. The obtained data showed that treatment of Atflot1ko mutants with bacterial peptide preserves the activity of the Golgi complex and the ability of this structure to form early endosomes, which are directly involved in the transport of protective proteins to the site of pathogen penetration.
