Abstract: Intensive development of systemic biology involves intensification of such branches as proteomics and lipidomics, which are valid for systemic biology of plants. This trend is obvious due to the rapidly growing number of publications on proteomes and lipidomes of plant cells, tissues, and whole organs. Particulars of the plant nuclei, mitochondria, and chloroplasts have been rather well detailed in this regard. However, these data are scarce concerning the tonoplast, Golgi apparatus, endoplasmic reticulum, and other single-membrane organelles of the plant cell. This review surveys the current concepts related to specificity of protein and lipid spectra in the membrane structures of plant cells. The little data describing changes in these parameters in the course of development and under stress pressure are also analyzed.
