Charakterizace FLOTILLINů and HYPERSENSITIVE INDUCED RESPONSE proteinů u Arabidopsis thaliana - dynamika, interakce a funkce / Characterization of Arabidopsis thaliana FLOTILLINs and HYPERSENSITIVE INDUCED RESPONSE proteins - dynamics, interactions and functions

This work is a collection of three research articles and one review article focused on flotillins (FLOTs) and hypersensitive induced reaction proteins (HIRs) in Arabidopsis thaliana. FLOTs and HIRs are closely related membrane-associated proteins forming two subfamilies both belonging to SPFH domain superfamily. While FLOTs are present in organisms of all evolutionary lineages HIRs are plant specific proteins. The review article sums up the knowledge gained on FLOTs and HIRs from different organisms in terms of cellular localization, interaction with cellular membranes and with other proteins, and physiological functions. The research articles were targeted at three aspects of AtFLOTs and AtHIRs: involvement in response to exogenous stimuli; determination of protein interactors; and subcellular localization and dynamics. The first aspect was approached by transcription measurement of AtFLOTs and phenotypic screen of single loss-of-function mutants of AtFLOTs upon various treatments covering biotic and abiotic stress and phytohormone application. Although we observed changes in transcription none of the treatments provoked a phenotype manifestation in any of AtFLOT mutants. In the second article we focused on interactome of AtFLOT2 and performed co- immunoprecipitation followed by mass spectrometry...
