Abstract
History of the discovery, formation, structural and biochemical traits of the protein bodies, derivatives of the granular endoplasmic reticulum (GER) that are known as ER-bodies, are reviewed. The functions of ER-bodies in cell vital activity mainly in Arabidopsis thaliana are reported. The highly specific component of ER-bodies, β-glucosidase enzyme, is described and its protecting role for plants under effect of abiotic and biotic factors is characterized. Based on the analytical review of the literature, it is shown that ER-bodies and the transcription factor NAI2 are unique to species of the family Brassicaceae. The specificity of the system GER – ER-bodies for Brassicaceae and thus the fundamental and applied importance of future research of mechanisms of its functioning in A. thaliana and other Brassicaceae species are emphasized.

Summary
Protein bodies of the endoplasmic reticulum in Arabidopsis thaliana (Brassicaceae): origin, structural and biochemical features, functional significance. Похідні від ГЕР, було описано в коренях трансгенних рослин Arabidopsis thaliana (L.) Heynh., які містили зелений флуоресцентний білок (green fluorescent protein, GFP), (Haseloff et al, 1997; Gunning, 1998; Ridge et al, 1999; Mitsuhashi et al, 2000; Hawes et al, 2001; Hayashi et al, 2001) та названо ЕР-тільцями, (Hayashi et al, 2001), хоча їх ще деякий час називали "таємничими органелами" (Hawes et al, 2001) або "веретеноподібними тільцями" ("fusiform bodies") (Nelson et al, 2004).
